Prompt and accurate diagnosis of infantile hemangiomas is essential to prevent potential complications. This can be difficult due to high rates of misdiagnosis and poor access to pediatric dermatologists. In this study, we trained an artificial intelligence algorithm to diagnose infantile hemangiomas based on clinical images. Our algorithm achieved a 91.7% overall accuracy in the diagnosis of facial infantile hemangiomas.

The COVID-19 pandemic prompted a rapid expansion in the use of telemedicine. This study aimed to assess the experiences of hemangioma specialists utilizing telemedicine during the COVID-19 pandemic to evaluate and manage infantile hemangiomas (IH), including perceived effectiveness of different modalities and barriers to care delivery.Multicenter cross-sectional study asking providers to describe their experiences using telemedicine for initial evaluation of IH from March to September 2020.The study included 281 patients from 15 medical centers internationally. Median time from referral to evaluation was 17 days. Median physician confidence in performing evaluations via telemedicine was 95.0 (IQR 90.0-100.0). Most evaluations were performed via video communication with photographs or audio communication with photographs; when not initially available, photographs were requested in 51.4%. Providers preferred follow-up modalities that included photographs.Physicians with extensive expertise in managing IH are confident in their abilities to assess and manage IH via telemedicine including initiating treatment in patients without risk factors for beta-blocker therapy. There was a preference for hybrid modalities that included photographs. The data suggest that telemedicine can be effective for managing IH and may decrease wait times and improve specialist reach to underserved areas.

Inhibitors of mammalian target of rapamycin function to downregulate cell growth and proliferation and have off-label use in pediatrics for vascular malformations. Hypertriglyceridemia is a known side effect of mammalian target of rapamycin (mTOR) inhibitors. Further studies to better understand the incidence and treatment of hypertriglyceridemia in infants and neonates are warranted.

We present three African American infants with segmental, ulcerated infantile hemangiomas and concomitant, persistent hypertension. When treated with beta-blocker therapy, the hemangiomas decreased in size and the ulcerations resolved, but there was no impact on the elevated blood pressure in one of our patients. We failed to identify any associations between infantile hemangioma and hypertension in the literature.

Bathing suit ichthyosis (BSI) is a subtype of autosomal recessive congenital ichthyosis (ARCI) characterized by the development of large platelike scales mainly limited to the trunk. It is caused by temperature sensitive variants in transglutaminase 1, encoded by the gene TGM1. We describe a rare case of intrafamilial variation in phenotypic expressivity in two Burmese siblings with BSI that demonstrates the heterogeneity of the disorder within the same family and even in the same individual across time. We also present a concise review of the genotypic spectrum of BSI from 54 cases reported in the literature as evidence that both environmental and additional genetic factors can significantly alter the clinical phenotype.

Background Pediatric Drug reaction with eosinophilia and systemic symptoms (DRESS) is an uncommon disease that can be difficult to diagnose. This case series and literature review highlights the clinical features of pediatric DRESS and underscores the differential diagnoses, culprit medications, and need for clinical follow-up to detect associated autoimmune sequelae. Objective To describe the clinical and laboratory features of pediatric DRESS, identify associated culprit medications, and discuss the natural history of disease. Methods Ten cases of pediatric DRESS were identified in the electronic medical record by searching the inpatient dermatology consultation list at Indiana University between 2013 and 2018. Clinical and laboratory data were collected including demographics, differential diagnoses, culprit medications, resolution of disease, and autoimmune sequelae. Results Pediatric patients with DRESS presented at a mean age of 11.5 years and demonstrated a mean time from drug initiation to onset of symptoms of 4 weeks. The most common inciting drugs included antibiotics (62.5%) followed by antiepileptics (37.5%). Rash and transaminitis resolved by 3 weeks, and 20% of patients, all female, developed autoimmune sequelae including Hashimoto's thyroiditis and an undifferentiated connective tissue disorder and occurred at an average of 14.5 weeks after diagnosis. Limitations This was a small retrospective study of an uncommon clinical diagnosis at a single institution. Conclusions Pediatric DRESS was most commonly caused by antibiotics which are being increasingly recognized in the literature as the predominant culprit medications. The development of autoimmune sequelae is a notable consequence that can present weeks after illness and may preferentially affect female patients.

Background The proliferative phase of infantile hemangiomas (IHs) is usually complete by 9 months of life. Late growth beyond age 3 years is rarely reported. Objective To describe the demographic and clinic characteristics of a cohort of patients with late growth of IH, defined as growth in a patient >3 years of age. Methods A multicenter, retrospective cohort study. Results In total, 59 patients, 85% of which were female, met the inclusion criteria. The mean first episode of late growth was 4.3 (range 3-8.5) years. Head and neck location (55/59; 93%) and presence of deep hemangioma (52/59; 88%) were common characteristics. P osterior fossa malformations, h emangiomas, a rterial anomalies, c ardiac defects, e ye abnormalities (PHACE) syndrome was noted in 20 of 38 (53%) children with segmental facial IH. Systemic therapy (corticosteroid or β-blocker) was given during infancy in 58 of 59 (98%) and 24 of 59 (41%) received systemic therapy (β-blockers) for late IH growth. Limitations The retrospective nature and ascertainment by investigator recall are limitations of the study. Conclusion Late IH growth can occur in children after 3 years of age. Risk factors include head and neck location, segmental morphology, and involvement of deep dermal/subcutaneous tissues.

The COVID‐19 pandemic has caused significant shifts in patient care including a steep decline in ambulatory visits and a marked increase in the use of telemedicine. Infantile hemangiomas (IH) can require urgent evaluation and risk stratification to determine which infants need treatment and which can be managed with continued observation. For those requiring treatment, prompt initiation decreases morbidity and improves long‐term outcomes. The Hemangioma Investigator Group has created consensus recommendations for management of IH via telemedicine. FDA/EMA‐approved monitoring guidelines, clinical practice guidelines, and relevant, up‐to‐date publications regarding initiation and monitoring of beta‐blocker therapy were used to inform the recommendations. Clinical decision‐making guidelines about when telehealth is an appropriate alternative to in‐office visits, including medication initiation, dosage changes, and ongoing evaluation, are included. The importance of communication with caregivers in the context of telemedicine is discussed, and online resources for both hemangioma education and propranolol therapy are provided.

Background/objectives Epidermolysis bullosa is a group of diseases caused by mutations in skin structural proteins. Availability of genetic sequencing makes identification of causative mutations easier, and genotype-phenotype description and correlation are important. We describe six patients with a keratin 5 mutation resulting in a glutamic acid to lysine substitution at position 477 (p.Glu477Lys) who have a distinctive, severe and sometimes fatal phenotype. We also perform in silico modeling to show protein structural changes resulting in instability. Methods In this case series, we collected clinical data from six patients with this mutation identified from their national or local epidermolysis bullosa databases. We performed in silico modeling of the keratin 5-keratin 14 coil 2B complex using CCBuilder and rendered with Pymol (Schrodinger, LLC, New York, NY). Results Features include aplasia cutis congenita, generalized blistering, palmoplantar keratoderma, onychodystrophy, airway and developmental abnormalities, and a distinctive reticulated skin pattern. Our in silico model of the keratin 5 p.Glu477Lys mutation predicts conformational change and modification of the surface charge of the keratin heterodimer, severely impairing filament stability. Conclusions Early recognition of the features of this genotype will improve care. In silico analysis of mutated keratin structures provides useful insights into structural instability.

Importance Recognizing segmental infantile hemangioma (IH) patterns is important for risk stratification and provides clues to pathogenesis. Previously, segmental hemangiomas were mapped to 4 facial regions, 3 corresponding to known facial metameres. Objectives To refine existing maps of facial segmental IHs, examine so-called indeterminate hemangiomas as they relate to known segmental patterns, and define a novel pattern of segmental scalp hemangiomas. Design, setting, and participants This retrospective cohort study was conducted at 4 pediatric dermatology centers (University of California, San Francisco; Indiana University; Medical College of Wisconsin; and Northwestern University/Ann & Robert H. Lurie Children's Hospital of Chicago) using photographic archives of patients younger than 12 years with segmental and indeterminate hemangiomas on the face and scalp. Clinical images were used to map hemangioma distribution onto standardized facial templates. Heat map densiometry identified recurrent patterns that were compared with previously published patterns of facial segmental hemangiomas. Patterns of indeterminate hemangiomas were compared with those of segmental hemangiomas. Data collection took place in 2017, and analysis took place from 2017 to 2019. Main outcomes and measures Distribution and patterning of segmental and indeterminate IHs of the face and scalp. Results A total of 549 IHs were mapped. The borders of the frontotemporal (S1) and frontonasal (S4) segments agreed with previous segmental maps; however, the maxillary (S2) and mandibular (S3) segment borders differed with respect to the preauricular skin. In contrast with previous reports, preauricular skin segregated with the mandibular (S3) rather than the maxillary (S2) segment. Indeterminate hemangiomas occurred within and respected the same borders as segmental hemangiomas. Hemangiomas on the lateral scalp commonly occurred in a C shape extending from the posterior auricular region. Conclusions and relevance This cohort study provides an updated map of facial segmental IHs with redefined maxillary (S2) and mandibular (S3) segment borders. It provides evidence that indeterminate hemangiomas are partial segmental hemangiomas respecting anatomic boundaries of their larger segmental counterparts. A newly recognized C-shaped pattern of segmental scalp hemangioma is reported.

Background Initial propranolol recommendations for infantile hemangioma published in 2013 were intended as provisional best practices to be updated as evidence-based data emerged. Methods A retrospective multicenter study was performed to evaluate utility of prolonged monitoring after first propranolol dose and escalation(s). Inclusion criteria included diagnosis of hemangioma requiring propranolol of greater than or equal to 0.3 mg/kg per dose, younger than 2 years, and heart rate monitoring for greater than or equal to 1 hour. Data collected included demographics, dose, vital signs, and adverse events. Results A total of 783 subjects met inclusion criteria; median age at initiation was 112 days. None of the 1148 episodes of prolonged monitoring warranted immediate intervention or drug discontinuation. No symptomatic bradycardia or hypotension occurred during monitoring. Mean heart rate change from baseline to 1 hour was –8.19/min (±15.54/min) and baseline to 2 hours was –9.24/min (±15.84/min). Three preterm subjects had dose adjustments because of prescriber concerns about asymptomatic vital sign changes. No significant difference existed in pretreatment heart rate or in heart rate change between individuals with later adverse events during treatment and those without. Conclusion Prolonged monitoring for initiation and escalation of oral propranolol rarely changed management and did not predict future adverse events. Few serious adverse events occurred during therapy; none were cardiovascular.

Background/Objectives Infantile hemangiomas (IHs) are commonly encountered in primary care and most often remain asymptomatic, resolving without sequelae. Certain characteristics are associated with a greater risk of complications, associated anomalies, and disfigurement. The heterogeneous presentation poses a clinical challenge for physicians in determining the need for treatment and subspecialty referral. This study aims to evaluate the utility of the previously published Hemangioma Severity Scale (HSS) to predict the need for treatment. Methods This retrospective study included 106 patients with IHs seen in the Indiana University Dermatology Clinic in 2011. Data from electronic medical records and clinical photographs taken at patients' initial visits were used to score the hemangiomas using the HSS. Treatments used over 9 to 14 months of follow-up were recorded. Results Four HSS score subgroups were identified. Higher HSS scores correlated with the need for treatment; 98% of patients with HSS scores of 10 or greater received local or systemic therapy. Higher HSS scores also correlated with greater frequency of complications and risks of associated structural anomalies and permanent disfigurement. Scores did not correlate with sex, age at initial presentation, history of bleeding or pain, or IH size. Conclusions The HSS may be a useful tool for primary care physicians in identifying high-risk IHs that may benefit from therapy. This easy-to-use scale can improve clinical outcomes by identifying which patients need intervention to minimize complications. IHs with total HSS scores of 6 or greater should be referred for subspecialty evaluation.

Background Twins have a higher-than-expected risk of infantile hemangiomas (IHs), but the exact reasons for this association are not clear. Comparing concordant and discordant twin pairs might help elucidate these factors and yield more information about IH risk factors. Methods A prospective cohort study of twin pairs from 12 pediatric dermatology centers in the United States, Canada, Argentina, and Spain was conducted. Information regarding maternal pregnancy history, family history of vascular birthmarks, zygosity (if known), and pregnancy-related information was collected. Information regarding twins (N = 202 sets) included birthweight, gestational age (GA), presence or absence of IHs, numbers and subtypes of IHs, presence of other birthmarks, and other medical morbidities. Results Two hundred two sets of twins were enrolled. Concordance for IH was present in 37% of twin pairs. Concordance for IH was inversely related to gestational age (GA), present in 42% of GA of 32 weeks or less, 36% of GA of 33 to 36 weeks, and 32% of GA of 37 weeks or more. Twins of GA of 34 weeks or less were more than two and a half times as likely to be concordant as those of GA of 35 weeks or more (odds ratio (OR) = 2.66, 95% confidence interval (CI) = 1.42–4.99; p < 0.01). In discordant twins, lower birthweight conferred a high risk of IH; of the 64 sets of twins with 10% or greater difference in weight, the smaller twin had IH in 62.5% (n = 40) of cases, versus 37.5% (n = 24) of cases in which the higher–birthweight twin was affected. Zygosity was reported in 188 twin sets (93%). Of these, 78% were dizygotic and 22% monozygotic. There was no statistically significant difference in rates of concordance between monozygotic twins (43%, 18/42) and dizygotic twins (36%, 52/146) (p = 0.50). In multivariate analysis comparing monozygotic and dizygotic twins, adjusting for effects of birthweight and sex, the likelihood of concordance for monozygotic was not appreciably higher than that for dizygotic twins (OR = 1.14, 95% CI = 0.52–2.49). Female sex also influenced concordance, confirming the effects of female sex on IH risk. The female-to-male ratio was 1.7:1 in the entire cohort and 1.9:1 in those with IH. Of the 61 concordant twin sets with known sex of both twins, 41% were female/female, 43% were female/male, and 16% were male/male. Conclusions These findings suggest that the origin of IHs is multifactorial and that predisposing factors such as birthweight, sex, and GA may interact with one another such that a threshold is reached for clinical expression.

Background/Objectives Infantile hemangiomas are common vascular tumors. Identifying sites of predilection may provide insight into pathogenesis. Previous studies have suggested a predilection for the boundary of facial metameres. The objective was to observe patterns of localized hemangiomas on the face and scalp, determine sites of predilection, and place these patterns in a developmental context. Methods Results A retrospective review of photographic archives at 10 Hemangioma Investigator Group pediatric dermatology centers identified localized infantile hemangiomas of the face and scalp. Heat map software was used to identify areas of predilection. Dot maps were used to assess frequency, and densities of infantile hemangiomas were compared between facial units using t-testing. The scalp was divided into quintiles to assess relative frequencies. Four thousand one hundred fifty-three focal face and scalp infantile hemangiomas were mapped, of which 2962 (71%) were mapped to a frontal facial template. On the face, 73.8% (2186/2962) of hemangiomas occurred along the midline axis or perpendicularly across the ocular axis in a cross-shaped area of predilection intersecting at the glabella. Scalp hemangiomas show a predilection for the midline, with 149/295 (50.5%) noted on the top of the scalp at the midline (P < 0.001). Localized hemangiomas do not demonstrate a preferential laterality. Conclusion The distribution of localized infantile hemangiomas of the face and scalp is not random. There is preferential involvement of the midline face and scalp and the ocular axis. The regions corresponding to the boundaries between the embryonic facial segments, including the maxillary and mandibular metameres, are not accentuated in the distribution of infantile hemangiomas.

Desmoplakin mutations are associated with a wide variety of phenotypes affecting the skin, nails, hair, and heart. A 21-month-old boy was born with multiple erosions resembling epidermolysis bullosa, complete alopecia, nail dystrophy, palmoplantar keratoderma, and areas of follicular hyperkeratosis. He was found to have two heterozygous mutations in the desmoplakin gene: c.478 C>T in exon 4 (p.Arg160X) and c.3630T>A in exon 23 (Tyr1210X). This case expands the clinical spectrum associated with desmoplakin mutations and highlights a mutation in exon 23 that has not been previously reported in the literature.

The cause of PHACE syndrome is unknown. In a study of 218 patients, we examined potential prenatal risk factors for PHACE syndrome. Rates of pre-eclampsia and placenta previa in affected individuals were significantly greater than in the general population. No significant risk factor differences were detected between male and female subjects.

Infantile hemangiomas (IHs) are common neoplasms composed of proliferating endothelial-like cells. Despite the relative frequency of IH and the potential severity of complications, there are currently no uniform guidelines for treatment. Although propranolol has rapidly been adopted, there is significant uncertainty and divergence of opinion regarding safety monitoring, dose escalation, and its use in PHACE syndrome (PHACE = posterior fossa, hemangioma, arterial lesions, cardiac abnormalities, eye abnormalities; a cutaneous neurovascular syndrome characterized by large, segmental hemangiomas of the head and neck along with congenital anomalies of the brain, heart, eyes and/or chest wall). A consensus conference was held on December 9, 2011. The multidisciplinary team reviewed existing data on the pharmacologic properties of propranolol and all published reports pertaining to the use of propranolol in pediatric patients. Workgroups were assigned specific topics to propose protocols on the following subjects: contraindications, special populations, pretreatment evaluation, dose escalation, and monitoring. Consensus protocols were recorded during the meeting and refined after the meeting. When appropriate, protocol clarifications and revision were made and agreed upon by the group via teleconference. Because of the absence of high-quality clinical research data, evidence-based recommendations are not possible at present. However, the team agreed on a number of recommendations that arose from a review of existing evidence, including when to treat complicated IH; contraindications and pretreatment evaluation protocols; propranolol use in PHACE syndrome; formulation, target dose, and frequency of propranolol; initiation of propranolol in infants; cardiovascular monitoring; ongoing monitoring; and prevention of hypoglycemia. Where there was considerable controversy, the more conservative approach was selected. We acknowledge that the recommendations are conservative in nature and anticipate that they will be revised as more data are made available. Pediatrics 2013;131:128-140

PHACE syndrome is a rare neurocutaneous disorder, with a complex pathogenesis. It presents with a large facial hemangioma associated with anomalies of the posterior fossa of the brain, arterial anomalies, cardiac anomalies, coarctation of the aorta, and eye anomalies. Ocular abnormalities are rare. We report the first published case of an infant with PHACE syndrome and Peters anomaly.

Background Practitioners who work with children with posterior fossa, facial hemangiomas, arterial anomalies, cardiovascular anomalies, and abnormalities of the eye (PHACE) syndrome need information about neurodevelopmental outcomes to provide appropriate anticipatory guidance and education for parents. This study aimed to determine the neurodevelopmental outcomes in children with PHACE syndrome and identify which children may be at greatest risk for delays. Methods Children with a diagnosis of PHACE syndrome (ages 4–18 yrs) were recruited from the PHACE Syndrome International Clinical Registry and Genetic Repository. Participants (n = 25) underwent a neurodevelopmental evaluation at a children's hospital tertiary care referral center between 2009 and 2013. Children completed standardized neurocognitive tests assessing multiple domains. Parents completed standardized questionnaires assessing behavioral and emotional functioning. Results Results were analyzed according to cohort and individual subject. Mean scores for the cohort did not differ significantly from test norms in most domains. The only subtest that the cohort scored lower on than test norms was Word Structure, a language task. Forty-four percent of the sample scored within the normal range in all domains, 28% had one score in the at-risk range (1–2 standard deviations [SDs] below the mean), 12% had two or more scores in the at-risk range, and 16% had at least one score in the impaired range (>2 SDs below the mean). Conclusion Although most children in this cohort of patients with PHACE syndrome did not have significant neurodevelopmental deficits, a subset of patients had delays in multiple areas. Practitioners who work with these children should routinely ask about neurocognitive and developmental skills. Children with more severe phenotypes should be referred for appropriate evaluations and intervention services.

Patients with atopic dermatitis (AD) are predisposed to infection with Staphylococcus aureus, which worsens their skin disease; it has been postulated that the lack of antimicrobial peptides due to aberrant allergic inflammation in skin with AD could mediate this enhanced bacterial susceptibility. We sought to characterize the amounts of S. aureus and biological products found in infected AD lesions and whether treatment with topical corticosteroids and oral cephalexin as the only antimicrobial improved outcomes. Fifty-nine children with clinically and S. aureus-positive impetiginized lesions of AD were enrolled in this study. A lesion was graded clinically using the Eczema Area and Severity Index, and wash fluid was obtained from the lesion for quantitative bacterial culture and antibiotic sensitivities and measurement of bacterial products and cytokines. Subjects were re-evaluated 2 weeks after treatment. Improvement in the clinical and inflammatory characteristics of impetiginized lesions were noted, even in the 15% of lesions infected with Methicillin-resistant S. aureus (MRSA). In a subgroup of subjects whose lesions did not contain S. aureus 2 weeks after initiating treatment, beta-defensin levels were higher at both visits than in normal skin. Treatment of uncomplicated impetiginized pediatric AD with topical corticosteroids and cephalexin results in significant clinical improvement, even in subjects infected with MRSA. We propose that the inhibition of abnormal inflammation by the treatment regimen, resulting in the high levels of defensins, is involved in the improvement of AD and that systemic antibiotics do not appear to be necessary in secondary impetiginized AD.

Multiple cutaneous infantile hemangiomas have been associated with hepatic hemangiomas. Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. The aim of this study was to determine the frequency with which hepatic hemangiomas occur in infants with five or more cutaneous infantile hemangiomas compared to those with one to four cutaneous infantile hemangiomas and to characterize the clinical features of these hepatic hemangiomas. A multicenter prospective study of children with cutaneous infantile hemangiomas was conducted at pediatric dermatology clinics at Hemangioma Investigator Groups sites in the United States, Canada, and Spain between October 2005 and December 2008. Data were collected, and abdominal ultrasonography was performed on infants younger than 6 months old with five or more cutaneous infantile hemangiomas and those with one to four cutaneous infantile hemangiomas. Twenty-four (16%) of the 151 infants with five or more cutaneous infantile hemangiomas had hepatic hemangiomas identified on abdominal ultrasound, versus none of the infants with fewer than five (p = 0.003). Two of the 24 infants with hepatic hemangiomas received treatment specifically for their hepatic hemangiomas. Infants with five or more cutaneous infantile hemangiomas have a statistically significantly greater frequency of hepatic hemangiomas than those with fewer than 5. These findings support the recommendation of five or more cutaneous infantile hemangiomas as a threshold for screening infants younger than 6 months old for hepatic hemangiomas but also demonstrate that the large majority of these infants with hepatic hemangiomas do not require treatment.

Objective To prospectively evaluate a cohort of patients with infantile hemangioma in the midline lumbosacral region for spinal anomalies to determine the positive predictive value of infantile hemangioma for occult spinal anomalies and to make evidence-based recommendations for screening. Study design A multicenter prospective cohort study was performed at 9 Hemangioma Investigator Group sites. Results Intraspinal abnormalities were detected in 21 of 41 study participants with a lumbosacral infantile hemangioma who underwent a magnetic resonance imaging evaluation. The relative risk for all patients with lumbosacral infantile hemangiomas for spinal anomalies was 640 (95% confidence interval [CI], 404-954), and the positive predictive value of infantile hemangioma for spinal dysraphism was 51.2%. Ulceration of the hemangioma was associated with a higher risk of having spinal anomalies. The presence of additional cutaneous anomalies also was associated with a higher likelihood of finding spinal anomalies; however, 35% of the infants with isolated lumbosacral infantile hemangiomas had spinal anomalies, with a relative risk of 438 (95% CI, 188-846). The sensitivity for ultrasound scanning to detect spinal anomalies in this high-risk group was poor at 50% (95% CI, 18.7%-81.3%), with a specificity rate of 77.8% (95% CI, 40%-97.2%). Conclusions Infants and children with midline lumbosacral infantile hemangiomas are at increased risk for spinal anomalies. Screening magnetic resonance imaging is recommended for children with these lesions. (J Pediatr 2010; 157:789-94).

Propranolol has recently been reported to be useful in the treatment of infantile hemangiomas. However, there are still many questions regarding the dosage, duration, and method of delivery.In this retrospective, observational case series, all patients had complete eye examinations and were found to have vision-threatening hemangiomas. All patients had a baseline electrocardiogram. Outpatient, oral propranolol therapy was initiated between 3 weeks and 12 months of age. The dosage was slowly increased to 2 mg/kg daily over the course of 1-2 weeks. Response to therapy was deemed "excellent" (50% reduction in size), "good" (decreased size but50%), "fair" (no further growth), or "poor" (continued growth or intolerable adverse effects).A total of 17 patients were treated with oral therapy. Of these, 10 had excellent results, 6 had a good response, 1 fair, and none poor. Mild adverse effects were noted in 6 of the 17 patients and included the following: increased gastric reflux lasting 1 week, intermittent fatigue during the first 2 weeks, gastrointestinal upset, and slight "shakiness" with a missed dose. No symptoms were severe enough to discontinue treatment. All families were satisfied with the treatment.Outpatient propranolol treatment reduced the size or stopped the growth of all hemangiomas treated, with excellent response in more than half of all patients treated and only minor side effects. Although this is a small initial series, we are encouraged with the efficacy of this treatment modality in comparison with other currently available treatment options.

OBJECTIVES. Infantile hemangiomas often are inapparent at birth and have a period of rapid growth during early infancy followed by gradual involution. More precise information on growth could help predict short-term outcomes and make decisions about when referral or intervention, if needed, should be initiated. The objective of this study was to describe growth characteristics of infantile hemangioma and compare growth with infantile hemangioma referral patterns.METHODS. A prospective cohort study involving 7 tertiary care pediatric dermatology practices was conducted. Growth data were available for a subset of 526 infantile hemangiomas in 433 patients from a cohort study of 1096 children. Inclusion criteria were age younger than 18 months at time of enrollment and presence of at least 1 infantile hemangioma. Growth stage and rate were compared with clinical characteristics and timing of referrals.RESULTS. Eighty percent of hemangioma size was reached during the early proliferative stage at a mean age of 3 months. Differences in growth between hemangioma subtypes included that deep hemangiomas tend to grow later and longer than superficial hemangiomas and that segmental hemangiomas tended to exhibit more continued growth after 3 months of age. The mean age of first visit was 5 months. Factors that predicted need for follow-up included ongoing proliferation, larger size, deep component, and segmental and indeterminate morphologic subtypes.CONCLUSIONS. Most infantile hemangioma growth occurs before 5 months, yet 5 months was also the mean age at first visit to a specialist. Recognition of growth characteristics and factors that predict the need for follow-up could help aid in clinical decision-making. The first few weeks to months of life are a critical time in hemangioma growth. Infants with hemangiomas need close observation during this period, and those who need specialty care should be referred and seen as early as possible within this critical growth period.

Objectives We sought to measure the type, content, and quality of World Wide Web sites retrieved when conducting an Internet search for infantile hemangiomas. Methods Fifty World Wide Web sites from a Google search for "hemangioma" were examined. Relevant sites were characterized, and content was evaluated by 8 pediatric dermatologists. Results The most accurate subjects were the description of risk factors and natural history, whereas the least accurate areas were photographic representation of the disease and presentation of treatment options. Four sites were considered accurate, and the majority of raters would recommend these sites to parents. Limitations Internet sites and search results change. Conclusions An Internet search for information about infantile hemangiomas yields few sites that accurately depict the full disease spectrum from innocuous to severe. Online educational resources containing a broader overview of the real disease spectrum of infantile hemangiomas are needed. Such sites should include large numbers of photographs, evidence-based content, and resources for parental support.

Objectives To characterize demographic, prenatal, and perinatal features of patients with infantile hemangiomas and to determine the importance of these factors in predicting rates of complication and treatment. Study design We conducted a prospective study at 7 U.S. pediatric dermatology clinics. A consecutive sample of 1058 children, aged 12 years and younger, with infantile hemangiomas was enrolled between September 2002 and October 2003. A standardized questionnaire was used to collect demographic, prenatal, perinatal, and hemangioma-specific data. National Vital Statistic System Data (NVSS) was used to compare demographic variables and relevant rates of prenatal events. Results In comparison with the 2002 United States National Vital Statistics System birth data, we found that infants with hemangiomas were more likely to be female, white non-Hispanic, premature ( P P P Conclusions Infants with hemangiomas are more likely to be female, white non-Hispanic, premature, and products of multiple gestations. Prenatal associations include older maternal age, placenta previa, and pre-eclampsia. No demographic, prenatal, and perinatal factors predicted higher rates of complications or need for treatment.

BACKGROUND AND OBJECTIVES: Propranolol is first-line therapy for problematic infantile hemangiomas (IHs). Rebound growth after propranolol discontinuation is noted in 19% to 25% of patients. Predictive factors for rebound are not completely understood and may alter the management approach. The goal of the study was to describe a cohort of patients with IHs treated with propranolol and to identify predictors for rebound growth. METHODS: A multicenter retrospective cohort study was conducted in patients with IHs treated with propranolol. Patient demographic characteristics, IH characteristics, and specifics of propranolol therapy were obtained. Episodes of rebound growth were recorded. Patients’ responses to propranolol were evaluated through a visual analog scale. RESULTS: A total of 997 patients were enrolled. The incidence of rebound growth was 231 of 912 patients (25.3%). Mean age at initial rebound was 17.1 months. The odds of rebound among those who discontinued therapy at CONCLUSIONS: Rebound growth occurred in 25% of patients, requiring modification of systemic therapy in 15%. Predictive factors for rebound growth included age of discontinuation, deep IH component, and female gender. Patients with these predictive factors may require a prolonged course of therapy.

Background: Infantile hemangiomas (IH) on the extremities have not been systematically studied. Objective: We sought to describe the clinical characteristics and distribution patterns of IH affecting acral surfaces and to explore the relationship among these patterns, limb development, and IH pathogenesis. Methods: This was a retrospective multicenter cohort study. Photographic archives from 4 tertiary pediatric dermatology referral centers were searched for patients with IH larger than 1 cm and involving 1 or more digit. Hemangioma location, distribution, and morphologic subtype were recorded. Medical records were reviewed for demographic and clinical data. Results: In all, 73 patients were identified. The most common IH pattern resembled that of a "biker glove" (73%), followed by localized IH on the distal digits (14%), segmental IH extending over the distal digits (8%), and intermediate patterns (5%). Overall, 63% of acral IH were segmental, 26% indeterminate, and 11% localized. Five patients had associated structural anomalies. Complications were noted in 33% of cases. Limitations: Limitations were retrospective study design; selection bias based on recall and photography; documentation and follow-up were not standardized across institutions; and treatment information may not reflect current approaches. Conclusion: Acral IH display specific patterns and are associated with a relatively high risk of ulceration.

Background Noninvoluting congenital hemangioma (NICH) is a distinct vascular tumor of infancy. Objective We describe the clinical characteristics, histopathology, imaging, and natural history of NICH and compare our findings with previous reports. Methods We conducted a retrospective review of charts and photographic databases from 2 vascular anomaly centers over a 15-year period. Results Thirty cases of NICH were identified. All patients had fully formed vascular lesions at birth that demonstrated a nonprogressive course. The trunk and lower extremities were preferred sites and there was a female predominance. Thirteen of 30 patients reported pain. Focal necrosis and scarring was seen in a minority. Doppler studies, when performed, confirmed high vascular flow. Microscopic evaluation of 4 excised lesions showed lobular areas of endothelial cell proliferation directly adjacent to ectatic malformed vessels. Immunohistochemical studies demonstrated absence of glucose transporter-1 protein expression in every case. Wilms tumor–1 positivity was observed in lobular areas. The larger vessels did not stain with Wilms tumor–1, but some displayed D2-40 positivity. Limitations Patients were referred to university-based pediatric vascular anomaly centers, with potential bias toward more severe or extensive cases. Conclusions This retrospective study highlights the unique clinical and histopathologic features of NICH.

Pyoderma gangrenosum (PG) is a painful, ulcerating neutrophilic dermatosis commonly associated with a variety of underlying systemic conditions. We report a child with neurofibromatosis-1 (NF-1) and an aseptic splenic abscess who developed multifocal PG in areas of iatrogenic skin trauma. There is no clinical evidence or theoretical basis to suggest a causal relationship between NF-1 and PG. Systemic corticosteroid and cyclosporine therapy led to complete resolution of the lesions.

Objectives To develop instruments that measure the severity of infantile hemangiomas (Hemangioma Severity Scale [HSS]) and the complications of infantile hemangiomas for longitudinal use (Hemangioma Dynamic Complication Scale [HDCS]). Design Instrument development and reliability study. Setting Academic research. Participants The HSS and the HDCS were developed through the collaborative effort of members of the Hemangioma Investigator Group Research Core, an expert multi-institutional research group. After development of the scales, 13 pediatric dermatologists used the HSS to score 20 different hemangiomas. In addition, 12 pediatric dermatologists used the HDCS to score hemangioma-related complications for 24 clinical scenarios. Interrater and intrarater reliability was measured for both scales. Main Outcome Measures Interrater and intrarater reliability. Results For the HSS, interrater reliability and intrarater reliability exceeded 99%. Similarly, the HDCS had a high rate of interrater agreement; for individual items, agreement among raters was 67% to 100%, with most clinical scenarios demonstrating greater than 90% agreement. Intrarater reliability was excellent for all individual items of the HDCS. Conclusion The HSS and the HDCS are reliable scales that can be used to measure the severity of infantile hemangiomas, including the severity of complications for longitudinal use.

There is evidence that early treatment of connective tissue in adolescence improves clinical outcomes; thus, recognition of the cutaneous manifestation of CTD is critical. This review summarizes the clinical features that are unique to children and adolescents in cutaneous (CLE) and systemic lupus erythematosus (SLE), juvenile dermatomyositis (JDM), juvenile systemic scleroderma (JSS), juvenile localized scleroderma (JLS), and juvenile inflammatory arthritis (JIA).

Objective To describe the clinical presentation and risk of PHACE syndrome in infants with large facial hemangiomas and concomitant airway hemangiomas. Design The study involved a case series of infants with cutaneous hemangiomas and airway hemangiomas extracted from a prospective multicenter cohort study. Data regarding clinical features, diagnosis, treatment, and clinical course were obtained from medical charts and physician intake forms. All patients were evaluated for PHACE syndrome using a standardized protocol. Setting Six academic pediatric dermatology clinics. Patients The study included 17 patients younger than 1 year who were diagnosed as having large (>22 cm 2 ) facial hemangiomas and airway hemangiomas. Results Thirteen patients (76%) had hemangiomas in the bilateral mandibular distribution. Other observed facial patterns included limited involvement of the lip and chin, unilateral reticular frontotemporal and preauricular hemangiomas, and large unilateral hemifacial hemangiomas. Fourteen patients (82%) had symptomatic airway involvement. All symptomatic patients had subglottic airway hemangiomas. The airway hemangioma was circumferential in 10 patients (58%) and more focal in distribution in 7 patients (42%). All patients were treated with oral prednisolone. Eleven patients required additional multimodal therapy. Eight patients (47%) met the criteria for PHACE syndrome. Conclusions Airway hemangiomas represent a potentially fatal complication of infantile hemangiomas. Our data highlight cutaneous presentations in patients with subglottic hemangiomas and large (>22 cm 2 ) cutaneous hemangiomas. PHACE syndrome was detected in 8 such patients (47%) in our series.

Multiple cutaneous infantile hemangiomas have been associated with hepatic hemangiomas. Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. The aim of this study was to determine the frequency with which hepatic hemangiomas occur in infants with five or more cutaneous infantile hemangiomas compared to those with one to four cutaneous infantile hemangiomas and to characterize the clinical features of these hepatic hemangiomas. A multicenter prospective study of children with cutaneous infantile hemangiomas was conducted at pediatric dermatology clinics at Hemangioma Investigator Groups sites in the United States, Canada, and Spain between October 2005 and December 2008. Data were collected, and abdominal ultrasonography was performed on infants younger than 6 months old with five or more cutaneous infantile hemangiomas and those with one to four cutaneous infantile hemangiomas. Twenty-four (16%) of the 151 infants with five or more cutaneous infantile hemangiomas had hepatic hemangiomas identified on abdominal ultrasound, versus none of the infants with fewer than five (p = 0.003). Two of the 24 infants with hepatic hemangiomas received treatment specifically for their hepatic hemangiomas. Infants with five or more cutaneous infantile hemangiomas have a statistically significantly greater frequency of hepatic hemangiomas than those with fewer than 5. These findings support the recommendation of five or more cutaneous infantile hemangiomas as a threshold for screening infants younger than 6 months old for hepatic hemangiomas but also demonstrate that the large majority of these infants with hepatic hemangiomas do not require treatment.

Summary Background Facial port-wine stains (PWSs) are usually isolated findings; however, when associated with cerebral and ocular vascular malformations they form part of the classical triad of Sturge–Weber syndrome (SWS). Objectives To evaluate the associations between the phenotype of facial PWS and the diagnosis of SWS in a cohort with a high rate of SWS. Methods Records were reviewed of all 192 children with a facial PWS seen in 2011–13. Adverse outcome measures were clinical (seizures, abnormal neurodevelopment, glaucoma) and radiological [abnormal magnetic resonance imaging (MRI)], modelled by multivariate logistic regression. Results The best predictor of adverse outcomes was a PWS involving any part of the forehead, delineated at its inferior border by a line joining the outer canthus of the eye to the top of the ear, and including the upper eyelid. This involves all three divisions of the trigeminal nerve, but corresponds well to the embryonic vascular development of the face. Bilateral distribution was not an independently significant phenotypic feature. Abnormal MRI was a better predictor of all clinical adverse outcome measures than PWS distribution; however, for practical reasons guidelines based on clinical phenotype are proposed. Conclusions Facial PWS distribution appears to follow the embryonic vasculature of the face, rather than the trigeminal nerve. We propose that children with a PWS on any part of the ‘forehead’ should have an urgent ophthalmology review and a brain MRI. A prospective study has been established to test the validity of these guidelines. What’s already known about this topic? Facial port-wine stains (PWSs) are common, but are rarely associated with Sturge–Weber syndrome (SWS). Early diagnosis of SWS is important to reduce ophthalmological and neural complications. Bilateral and ophthalmic division trigeminal nerve PWSs are thought to confer higher risk of SWS. What does this study add? The strongest predictor of SWS was found using a new classification of PWS based on the vascular embryological distribution and not the neural innervation of the face. We propose new guidelines for investigation of children with facial PWS based on this new classification of phenotype.

BACKGROUND AND PURPOSE: Cerebral and cervical arterial abnormalities are the most common non-cutaneous anomaly in PHACE syndrome, but the location and type of arterial lesions that occur have not been systematically assessed in a large cohort. Our aim was to characterize the phenotypic spectrum of arteriopathy, assess the frequency with which different arteries are involved, and evaluate spatial relationships between arteriopathy, brain structural lesions, and hemangiomas in PHACE syndrome. MATERIALS AND METHODS: Intracranial MRA and/or CTA images from 70 children and accompanying brain MR images in 59 patients with arteriopathy and PHACE syndrome were reviewed to identify the type and location of arterial lesions and brain abnormalities. Five categories of arteriopathy were identified and used for classification: dysgenesis, narrowing, nonvisualization, primitive embryonic carotid-vertebrobasilar connections, and anomalous arterial course or origin. Univariate logistic regression analyses were performed to test for associations between arteriopathy location, hemangiomas, and brain abnormalities. RESULTS: By study design, all patients had arterial abnormalities, and 57% had >1 form of arteriopathy. Dysgenesis was the most common abnormality (56%), followed by anomalous course and/or origin (47%), narrowing (39%), and nonvisualization (20%). Primitive embryonic carotid-vertebrobasilar connections were present in 20% of children. Hemangiomas were ipsilateral to arteriopathy in all but 1 case. The frontotemporal and/or mandibular facial segments were involved in 97% of cases, but no other specific associations between arteriopathy location and hemangioma sites were detected. All cases with posterior fossa anomalies had either ICA anomalies or persistent embryonic carotid-basilar connections. CONCLUSIONS: The arteriopathy of PHACE syndrome commonly involves the ICA and its embryonic branches, ipsilateral to the cutaneous hemangioma, with dysgenesis and abnormal arterial course the most commonly noted abnormalities. Brain abnormalities are also typically ipsilateral.

OBJECTIVES: A subgroup of patients with infantile hemangiomas have associated structural anomalies of the brain, cerebral vasculature, eyes, sternum, and/or aorta in the neurocutaneous disorder known as PHACE syndrome. The diagnosis has been broadly inclusive by using a case definition of a facial hemangioma plus ≥1 extracutaneous features, leading to numerous reports of potential associated disease features, many of uncertain significance. This consensus statement was thus developed to establish diagnostic criteria for PHACE syndrome. METHODS: A multidisciplinary group of specialists with expertise in PHACE syndrome drafted initial diagnostic criteria on the basis of review of published, peer-reviewed medical literature and clinical experience. The group then convened in both executive and general sessions during the PHACE Syndrome Research Conference held in November 2008 for discussion and used a consensus method. All conflicting recommendations were subsequently reconciled via electronic communication and teleconferencing. RESULTS: These criteria were stratified into 2 categories: (1) PHACE syndrome or (2) possible PHACE syndrome. Major and minor criteria were determined for the following organ systems: cerebrovascular, structural brain, cardiovascular, ocular, and ventral/midline. Definite PHACE requires the presence of a characteristic segmental hemangioma or hemangioma >5 cm on the face or scalp plus 1 major criterion or 2 minor criteria. Possible PHACE requires the presence of a hemangioma >5 cm on the face or scalp plus 1 minor criterion. The group recognized that it may be possible to have PHACE syndrome with a hemangioma affecting the neck, chest, or arm only or no cutaneous hemangioma at all. In such cases, fulfillment of additional required criteria would also lead to a possible PHACE diagnosis. CONCLUSIONS: These criteria represent current knowledge and are expected to enhance future assessments of PHACE syndrome. It is understood that modifications are to be expected over time to incorporate new research findings.

OBJECTIVES. Infantile hemangiomas are the most common tumor of infancy. Risk factors for complications and need for treatment have not been studied previously in a large prospective study. This study aims to identify clinical characteristics associated with complications and the need for therapeutic intervention. PATIENTS AND METHODS. We conducted a prospective cohort study at 7 US pediatric dermatology clinics with a consecutive sample of 1058 children, aged ≤12 years, with infantile hemangiomas enrolled between September 2002 and October 2003. A standardized questionnaire was used to collect data on each patient and each hemangioma, including clinical characteristics, complications, and treatment. RESULTS. Twenty-four percent of patients experienced complications related to their hemangioma(s), and 38% of our patients received some form of treatment during the study period. Hemangiomas that had complications and required treatment were larger and more likely to be located on the face. Segmental hemangiomas were 11 times more likely to experience complications and 8 times more likely to receive treatment than localized hemangiomas, even when controlled for size. CONCLUSIONS. Large size, facial location, and/or segmental morphology are the most important predictors of poor short-term outcomes as measured by complication and treatment rates.

PHACE (OMIM no. 606519) is a neurocutaneous syndrome that refers to the association of large, plaque-like, "segmental" hemangiomas of the face, with one or more of the following anomalies: posterior fossa brain malformations, arterial cerebrovascular anomalies, cardiovascular anomalies, eye anomalies, and ventral developmental defects, specifically sternal defects and/or supraumbilical raphe. The etiology and pathogenesis of PHACE is unknown, and potential risk factors for the syndrome have not been systematically studied. The purpose of this study was thus to determine (1) the incidence of PHACE and associated anomalies among a large cohort of hemangioma patients, (2) whether certain demographic, prenatal or perinatal risk factors predispose infants to this syndrome, and (3) whether the cutaneous distribution of the hemangioma can be correlated to the types of anomalies present. We undertook a prospective, cohort study of 1,096 children with hemangiomas, 25 of whom met criteria for PHACE. These 25 patients represented 20% of infants with segmental facial hemangiomas. Compared to previous reports, our PHACE patients had a higher incidence of cerebrovascular and cardiovascular anomalies. Two developed acute arterial ischemic stroke during infancy, while two with cardiovascular anomalies showed documented evidence of normalization, suggesting that both progressive and regressive vascular phenomena may occur in this syndrome. Correlation to the anatomic location of the hemangioma appears to be helpful in determining which structural abnormalities might be present. A comparison of demographic and perinatal data between our PHACE cases and the hemangioma cohort overall showed no major differences, except a trend for PHACE infants to be of slighter higher gestational age and born to slightly older mothers. Eighty-eight percent were female, a finding which has been noted in multiple other reports. Further research is needed to determine possible etiologies, optimal evaluation, and outcomes.

OBJECTIVES. Large facial infantile hemangiomas have higher rates of complications than small localized hemangiomas, more often require treatment, and can be associated with neurological, ophthalmologic, and cardiac anomalies (PHACE syndrome). The anatomic patterns of these hemangiomas are often referred to as “segmental” despite a lack of precise anatomic definitions. Our study aims to define “segmental” hemangiomas based on clinically observed patterns. Our secondary goal is to relate the observed patterns to currently accepted developmental patterns to gain insight into hemangioma pathogenesis and craniofacial development. METHODS. Photographic data were extracted from a large cohort of patients with infantile hemangiomas. We mapped 294 hemangiomas and recorded common morphologic patterns. Anatomic descriptions of the most common patterns were described and compared with accepted concepts of craniofacial development. RESULTS. Four primary segments were identified (Seg1–Seg4). Seg2 and Seg3 correspond with the previously recognized maxillary and mandibular prominences. Seg1 and Seg4 differ from standard human embryology texts. The frontotemporal segment, Seg1, encompasses the lateral forehead, anterior temporal scalp, and lateral frontal scalp. The segment Seg4, encompassing the medial frontal scalp, nasal bridge, nasal tip, ala, and philtrum, is substantially narrower on the forehead than the previously described frontonasal prominence. CONCLUSIONS. The patterns provide new clues regarding facial development. The observed patterns resemble previously described facial developmental units on the lower face but are distinctly different on the upper face. The patterns suggest that neural crest derivatives may play a role in the development of facial hemangiomas. Finally, these patterns (Seg1–Seg4) help standardize the nomenclature of facial segmental hemangiomas to analyze more effectively hemangioma risks and behavior.

We report on a new patient with clinical findings consistent with acro-dermato-ungual-lacrimal-tooth (ADULT) syndrome. The child had sparse hair, extensive freckling, lacrimal duct stenosis, oligodontia, dystrophic nails, reduced sweating, and bilateral athelia. Examination of his hands showed ulnar ray hypoplasia with bilateral fifth finger brachydactyly and camptodactyly. He also had surgical repair of an imperforate anus. Mutation analysis of TP63 showed a single nucleotide substitution, c.G518A, predicting a novel missense mutation, p.V114M in exon 4. This is the third mutation to be reported in TP63 in ADULT syndrome.
