Syphilis is an infection caused by Treponema pallidum. It is most commonly acquired through sexual transmission, although it can also be transmitted vertically across the placenta, resulting in congenital syphilis. Even with improved public health measures, testing, and treatment capabilities, primary, secondary, and congenital syphilis have all surged since 2012. Given this marked increase in both incidence and prevalence, here we present a comprehensive review of the clinical presentation, treatment, and management of congenital syphilis, with particular consideration given to the mucocutaneous manifestations of the disease in neonates., (© 2022 Wiley Periodicals LLC.)

Background/objective: Herpes simplex virus (HSV) infection acquired in utero may present with non-vesicular dermatologic findings in affected newborns, which may pose a diagnostic dilemma. We aimed to describe and assess the range of non-vesiculobullous skin lesions that neonates with intrauterine HSV infection may manifest at birth., Methods: We collected a multicenter case series and conducted a literature review of neonates with intrauterine HSV infection presenting with non-vesiculobullous cutaneous lesions., Results: Twenty-two cases were reviewed, including six managed clinically by members of our team and 16 identified in the literature. Four (18%) were associated with twin pregnancies, and thirteen (59%) cases occurred in premature infants. Only four (18%) mothers had a documented history of HSV infection. Twelve (55%) cases resulted in poor outcomes, including long-term neurologic sequelae or death. Cutaneous manifestations included erosions, ulcerations, crusted papules or plaques, calcinosis cutis, excoriations, macules (erythematous, hypopigmented, or hyperpigmented), cutaneous atrophy, contractures, and bruising. About one-third of neonates developed new-onset vesicular lesions within a week of birth; in each of these cases, accurate diagnosis and therapy were delayed until appearance of vesicles., Conclusions: The range of dermatologic findings associated with intrauterine HSV is extremely broad, and the various morphologies present at birth likely reflect different stages of the ongoing evolution of an HSV infection that began in utero. Clinicians should have a low threshold for HSV testing in premature neonates born with atypical cutaneous lesions, since early detection and treatment of HSV may reduce morbidity and mortality from systemic complications., (© 2021 The Authors.

Background/objectives: Pulsed dye laser (PDL) is the gold standard for treating port-wine birthmarks (PWBs), but no consensus exists regarding anesthetic techniques when performing PDL for PWB. Given potential adverse neurocognitive effects from general anesthesia (GA) exposure in early childhood, we sought to establish current attitudes and practice patterns regarding anesthesia when treating PWB with PDL., Methods: An electronic REDCap survey was distributed to members of the Pediatric Dermatology Research Alliance (PeDRA) and the Society for Pediatric Dermatology (SPD) via email. Aggregate, anonymized results were reported., Results: Among 47 respondents, the majority (83%) identified as board-certified pediatric dermatologists. When treating children <4 years old, 70% endorsed some use of topical anesthesia. Although 87% reported concerns about long-term side effects on development and school performance affecting their pursuit of GA, 61% reported use of GA for PDL in children <4 years old. All 4 (100%) respondents whose PDL was located in the operating room (OR) setting reported use of GA, compared to 6 of 17 (35%) respondents whose PDL machine was not located in the OR. Providers were more likely to use GA in patients between 1 and 4 years old (70%) compared to those <1 year old (2%)., Conclusions: Diverse practice patterns reiterate the need for a standardized anesthetic approach for PDL in young children and continued research on other factors (ie, location/accessibility of PDL, lesion size) impacting anesthesia choices. Given potential neurodevelopmental risks associated with GA, specific guidance to effectively minimize its use in favor of topical anesthetics should be provided., (© 2020 Wiley Periodicals LLC.)

Background: Infantile hemangiomas (IH) are the most common benign tumor of infancy. Although oral propranolol is currently first-line therapy, optimal dosing for treatment of IH remains debated. We sought to identify hemangioma characteristics associated with poor response to standard dosing (2 mg/kg/d) and to assess the therapeutic benefit of higher dosing., Methods: Retrospective chart review was conducted of 559 patients with IH seen at Johns Hopkins between 2008 and 2018, of whom 245 (44%) were treated with propranolol. Baseline characteristics were compared between patients who received increased propranolol dosing (≥2.5 mg/kg/d) and those who remained on standard dose (2 mg/kg/d). Changes in the Hemangioma Activity Score (HAS) during the increased dosage period were scored by two trained, blinded pediatric dermatologists., Results: Of 245 patients, 204 (83%) received standard 2 mg/kg/d propranolol dosing while 41 (17%) received a higher dose of ≥2.5 mg/kg/d. The most common location of IH in both groups was the face. In the increased dosage group, 85.4% of IH were of mixed or deep morphology with a mean greatest diameter of 4.6 cm. IH requiring increased dosing received longer courses of propranolol (mean of 389 vs. 282 days, P < .001) and underwent higher rates of excision by plastic surgery (26.8% vs. 5.9%, P < .001). Mean change in HAS over the period with dosage ≥2.5 mg/kg/d was minimal (-0.70; P < .001)., Conclusions: Most recalcitrant IH were located on the face, larger in diameter, and of mixed or deep morphology. Patients had little improvement in HAS score with increased propranolol dosing implemented late in the treatment course with over one-fourth ultimately receiving surgical excision., (© 2020 Wiley Periodicals LLC.)

Mycosis fungoides (MF) is the most common primary cutaneous lymphoma in pediatric patients. Given the indolent nature of MF, symptoms often present in childhood but may not be diagnosed as MF until adulthood. Delayed diagnosis is associated with poor long-term prognosis. Thus, increased clinician recognition and accurate diagnosis of early-stage MF in pediatric patients is critically important. In this review, we summarize the clinical features of the most common pediatric MF subtypes and highlight important differences between pediatric and adult MF. Moreover, we reviewed all pediatric MF case series published between 2008 and 2018 to analyze treatment modalities and identify emerging therapies. As treatment of pediatric MF is complex, selection of therapy varies significantly depending upon the specific clinical characteristics, disease severity, and patients' preferences., (© 2019 Wiley Periodicals, Inc.)

Staphylococcal scalded skin syndrome causes widespread skin denudation primarily in infants < 1 year old. Selection of empiric therapy is complicated by rising rates of antibiotic resistance in community-acquired staphylococcal infections. Consistent with a previous study, this retrospective review found that SSSS-associated isolates were more likely to be clindamycin-resistant and less likely to be methicillin-resistant compared to overall staphylococcal infections. We favor cephalosporins and penicillinase-resistant penicillins (eg, oxacillin) for empiric management of SSSS, with consideration of adding MRSA coverage in communities with high MRSA prevalence or failure to improve following several days of treatment., (© 2019 Wiley Periodicals, Inc.)

Objectives: To identify clinical factors associated with complications of periocular infantile hemangioma (IH) and monitor improvement in complication rates post-treatment., Methods: Retrospective cohort study. Eighty-nine patients diagnosed with periocular IH at a pediatric dermatology clinic of a tertiary care center between 2001 and 2013 were included with parental approval. Parents were interviewed by telephone between July and September of 2015, then again in January 2018 to inquire about ophthalmologic follow-up. Electronic medical records were reviewed from January 2001 through January 2018., Results: Sixty percent of patients demonstrated ocular sequelae, including astigmatism (33%), visual axis obstruction (29%), nasolacrimal duct obstruction (7%), ptosis (4%), amblyopia (3%), and strabismus (1%). Compared with superficial IH, deep and mixed IH had higher odds, 3.4 (P = 0.025) and 3.8 (P = 0.034), respectively, of developing ocular sequelae. All patients with astigmatism prior to involution of IH received systemic therapy, with a significant post-treatment decrease in the proportion of patients with astigmatism (40% to 18%, P = 0.027). Three-quarters of patients experienced complete IH involution by time of enrollment in kindergarten. Fifty-one (57.3%) patients received formal ophthalmologic evaluation confirmed through chart review or phone interview, with average follow-up duration of 51.2 months (range: 1.9, 99.3)., Conclusion: Deep and mixed IH were more likely to demonstrate ocular complications than superficial IH. Rate of astigmatism decreased with systemic therapy. Our study suggests that patients with periocular IH have a lower rate of amblyopia now compared with the prepropranolol era and emphasizes the importance of early treatment of periocular IH to prevent permanent visual sequelae., (© 2019 Wiley Periodicals, Inc.)

The most common causes of chronic nocturnal itching in children are atopic dermatitis and psoriasis, with lichen simplex chronicus and prurigo nodularis contributing to lesser degrees. Despite the prevalence of nocturnal itching, its pathophysiology remains poorly understood. The most troubling consequence of itching at night is poor quality of sleep. Poor sleep quality in children with nocturnal itching has been linked to adverse neurocognitive, behavioral, and physiologic outcomes, including poor performance in school, attention deficit hyperactivity disorder, short stature, hypertension, obesity, and impaired immune function. There is no consensus on the best management of nocturnal itching in children. We conducted a review of the literature evaluating the efficacy of various treatment options for children with chronic nocturnal pruritus. Our review found three recently conducted randomized controlled trials and one case report demonstrating the efficacy of topical corticosteroids, oral melatonin, and clonidine in reducing nocturnal itching or improving sleep quality in children with nocturnal pruritus. Future research is needed to elucidate the pathophysiology of nocturnal itching to best develop targeted, effective treatment strategies., (© 2018 Wiley Periodicals, Inc.)

Background/objectives: Pityriasis lichenoides is an uncommon papulosquamous disorder of unknown etiology. The objective of this study was to review the clinical features and treatment responses of individuals with pityriasis lichenoides seen at a tertiary referral center., Methods: Seventy-five patients diagnosed with pityriasis lichenoides between 1997 and 2013 were reviewed, and 46 had long-term follow-up via telephone interviews., Results: Fifty (67%) patients were diagnosed with pityriasis lichenoides chronica, 22 (29%) with pityriasis lichenoides et varioliformis acuta, and 3 (4%) with mixed pityriasis lichenoides chronica and pityriasis lichenoides et varioliformis acuta features. Mean ± standard deviation age at onset was 12 ± 13 years (median 8 years). Disease duration was significantly shorter for patients with pityriasis lichenoides et varioliformis acuta (35 ± 35 months) than for those with pityriasis lichenoides chronica (at least 78 ± 48 months). At long-term follow-up, 23 of 28 (82%) patients with pityriasis lichenoides chronica and 3 of 16 (19%) with pityriasis lichenoides et varioliformis acuta had active disease. None progressed to lymphomatoid papulosis or cutaneous T-cell lymphoma. Ten of 23 active pityriasis lichenoides chronica cases had residual pigmentary change independent of race and lasted at least 35 ± 20 months. The most effective treatments were phototherapy (47% response rate), heliotherapy (33%), topical corticosteroids (27%), and antibiotics (25%)., Conclusion: Pityriasis lichenoides is a predominantly pediatric disorder. The time course of pityriasis lichenoides chronica is significantly longer than that of pityriasis lichenoides et varioliformis acuta. Pityriasis lichenoides chronica may persist with pigmentary alterations in the absence of other signs of active inflammation. Treatment response is often limited, particularly for patients with pityriasis lichenoides chronica., (© 2018 Wiley Periodicals, Inc.)

Background: This study examines the clinical characteristics and demographics of teenage boys with horizontal striae distensae of the lower back in an outpatient setting., Methods: Retrospective medical chart reviews and telephone survey studies were completed on an outpatient cohort of 12 boys 11 to 17 years of age with a clinical diagnosis of transverse striae distensae of the lower back at a single-center, university-based, pediatric dermatology practice. We evaluated the clinical features of the striae, participant demographic characteristics, and past medical history. A review of the literature concerning risk factors was conducted using PubMed and Google Scholar., Results: Of the 14 patients we contacted, 12 agreed to participate. The average age of onset for the striae was 14.3 years. All boys were above the 50th percentile in height at the time of onset. Eight (66.7%) reported a significant growth spurt before the appearance of the stretch marks. Most were asymptomatic. None of the boys had a history of unmonitored exogenous steroid use or prior infection with Bartonella henselae or Borrelia burgdorferi. Only one (8.3%) had a chronic medical condition. Eleven (91.7%) had at least one first-degree relative with striae distensae., Conclusion: Our results indicate that horizontal striae distensae of the lower back in adolescent boys is associated with a rapid growth spurt, tall stature, and family history of striae distensae. There is no association between this type of striae distensae and any chronic medical condition, bacterial infection, or exogenous steroid use. Thus a careful review of systems and counseling without further medical testing is reasonable management., (© 2017 Wiley Periodicals, Inc.)

Background/objectives: Bullous impetigo (BI) is a common dermatologic condition, particularly in children, yet confusion regarding its diagnosis and treatment persists. This study measured pediatricians' ability to diagnose and appropriately treat BI and explored factors that might influence pediatricians' accuracy in managing BI., Methods: We administered an expert-validated survey to 64 pediatrics house staff and faculty at three Johns Hopkins Medicine facilities. The survey requested demographic information, diagnoses for five "unknown" cases, and preferred treatments for localized and widespread BI., Results: Overall, BI was diagnosed correctly 31.9% of the time. There was little difference between house staff and faculty performance, although faculty 50 years of age and older demonstrated better diagnostic acumen. Regarding treatment of localized BI, 92% of faculty members and 84.6% of house staff listed mupirocin as first- or second-line treatment. The second most common medication listed for localized BI was bacitracin. Regarding treatment of widespread BI, faculty listed cephalexin or clindamycin as first- or second-line treatment 56.0% of the time and house staff listed one of these two medications 51.3% of the time. Results for faculty 50 years of age and older were comparable., Conclusions: Improved pediatrician proficiency in the diagnosis and treatment of BI is needed for safe, cost-effective management. Physician age and experience appear to have a limited effect on the accuracy of BI diagnosis and management. Future educational efforts must be directed at trainees and their instructors., (© 2016 Wiley Periodicals, Inc.)

Background/objectives: Nasal infantile hemangiomas (IHs) pose serious medical complications and psychosocial stress if tumor involution is incomplete or prolonged. The objective was to determine which IH characteristics are associated with complications and are predictive of outcome, assessed as the presence of IHs or residual skin changes upon kindergarten entry, to better manage these lesions and counsel families., Methods: A retrospective chart review of all patients seen in the Division of Pediatric Dermatology at Johns Hopkins Medicine between 2001 and 2014 for nasal IHs (N = 89) was performed. A follow-up telephone interview with parents was conducted in June and July 2014., Results: Complications were observed in 39% of patients. Segmental and indeterminate IHs were more likely to have complications than focal IHs (p = 0.01). Mixed IHs were more likely to ulcerate than deep or superficial IHs (p = 0.01). Eighty percent of patients had treatment and 19% had surgery. Although IHs regressed by kindergarten entry in 70% of patients, 78% of these patients had residual skin changes. Mixed and superficial IHs left more residua than deep IHs (p = 0.04). A statistical comparison of treatments with respect to outcome at kindergarten entry could not be made because subgroups were too small and heterogeneous., Conclusion: Nasal IHs had higher rates of complications and treatment than previous reports of IHs at all body sites. Lesions of segmental and indeterminate type and mixed depth should be identified as high risk and treated accordingly. Parents may be counseled that most nasal IHs involute by kindergarten but leave residua and that early referral for treatment may be important for the best outcome., (© 2016 Wiley Periodicals, Inc.)

Background: The purpose is to investigate the demographics and course of common warts in children in an outpatient setting., Methods: A retrospective medical chart review and telephone survey study were completed on an outpatient cohort of children (0-17 yrs) with a clinical diagnosis of warts at a single-center, university-based pediatric dermatology practice. The main outcome measures included management, time to resolution, and associated factors of warts in children., Results: Of the 254 patients we contacted, 214 agreed to participate in the survey. The most commonly involved sites were the hands and the head and neck area. Most children received some form of therapy, but it is unclear that any form of treatment altered the course. However, children with a medical history of childhood infections or more than one anatomic site had significantly greater risk of having a longer time to resolution., Conclusion: Warts resolved in 65% of children by 2 years and in 80% within 4 years, regardless of treatment. With the exception of a history of childhood infections and having more than one anatomic site, time to resolution was not altered by wart or patient characteristics. Thus counseling without aggressive destructive treatment is a reasonable approach to managing warts in most children. Our findings will provide guidance in the process of shared decision making with parents and children., (© 2015 Wiley Periodicals, Inc.)

Despite the high prevalence of molluscum contagiosum (MC) in children, epidemiologic data on this common self-limited viral infection is limited. In this report we review our experience with the demographic characteristics, clinical characteristics, management, and time to resolution of MC in 170 children. A retrospective medical chart review and telephone survey were conducted on children younger than 16 years of age evaluated for MC in the Division of Pediatric Dermatology at the Johns Hopkins Children's Center, Baltimore, Maryland, from January 1, 2008, to December 31, 2011. Of 170 children with MC, 51.8% were female and 77.1% were Caucasian. The median age at diagnosis was 5 years and 46.5% had a history of atopic dermatitis (AD). Children with AD had significantly more MC lesions than those without (p < 0.05); 72.9% of children did not receive any treatment. MC lesions completely cleared within 12 months in 45.6% of treated and 48.4% of untreated children and within 18 months in 69.5% of treated and 72.6% of untreated children. Treatment (if any), sex, race, diagnosing physician, number of lesions at diagnosis, number of anatomic locations, or history of AD did not predict time to resolution of MC lesions. MC lesions completely resolved in approximately 50% of children within 12 months and in 70% within 18 months. Treatment did not shorten the time to resolution., (© 2015 Wiley Periodicals, Inc.)

We report seven patients with facial lichen striatus along the lines of Blaschko who presented to our pediatric dermatology unit between 2003 and 2009. The mean age of diagnosis was 4.6 years (range 2.5-9 years). Three of the cases were associated with atopic dermatitis, and one case presented with vitiligo. In the six patients for whom we have follow-up, all lesions resolved without pigmentary changes in an average of 11 months. This case series describes the distribution, presentation, and natural history of lichen striatus along facial lines of Blaschko. From our experience, clinical diagnosis and monitoring without biopsy is a reasonable approach to the management of uncomplicated lichen striatus, particularly when the face is involved., (© 2012 Wiley Periodicals, Inc.)

Bullous systemic lupus erythematosus is a subepidermal blistering disease that occurs only rarely in a subset of patients with systemic lupus erythematosus and even less commonly in pediatric patients. Autoimmunity in bullous systemic lupus erythematosus is characterized by the presence of circulating anti-type VII collagen antibodies. We report here a case of a child whose initial systemic lupus erythematosus presentation was a diffuse bullous eruption.

Three healthy children with an anogenital skin eruption, all of whom had undergone extensive medical evaluation and treatment, had undetected intestinal Crohn's disease. Biopsy of the skin showed noncaseating granulomas consistent with cutaneous Crohn's disease. Inflammatory bowel disease should be in the differential diagnosis of persistent nontender, erythematous papules, nodules, and plaques in the anogenital region.

Rationale: Care coordination has shown inconsistent results as a mechanism to reduce hospital readmission and postdischarge emergency department (ED) visit rates., Objective: To assess the impact of a supplemental care bundle targeting high-risk elderly inpatients implemented by hospital-based staff compared to usual care on a composite outcome of hospital readmission and/or ED visitation at 30 and 60 days following discharge., Patients/methods: Randomized controlled pilot study in 41 medical inpatients predisposed to unplanned readmission or postdischarge ED visitation, conducted at Baylor University Medical Center. The intervention group care bundle consisted of medication counseling/reconciliation by a clinical pharmacist (CP), condition specific education/enhanced discharge planning by a care coordinator (CC), and phone follow-up., Results: Groups had similar baseline characteristics. Intervention group readmission/ED visit rates were reduced at 30 days compared to the control group (10.0% versus 38.1%, P = 0.04), but not at 60 days (30.0% versus 42.9%, P = 0.52). For those patients who had a readmission/postdischarge ED visit, the time interval to this event was longer in the intervention group compared to usual care (36.2 versus 15.7 days, P = 0.05). Study power was insufficient to reliably compare the effects of the intervention on lengths of index hospital stay between groups., Conclusions: A targeted care bundle delivered to high-risk elderly inpatients decreased unplanned acute health care utilization up to 30 days following discharge. Dissipation of this effect by 60 days postdischarge defines reasonable expectations for analogous hospital-based educational interventions. Further research is needed regarding the impacts of similar care bundles in larger populations across a variety of inpatient settings., ((c) 2009 Society of Hospital Medicine.)

Objectives: Antiretroviral toxic neuropathy (ATN) is associated with dideoxynucleoside reverse transcriptase inhibitor use in patients infected with HIV, possibly as a result of mitochondrial toxicity. Acetyl-l-carnitine (ALC) has been linked to symptomatic improvement in ATN. We present an open-label single-arm pilot study to evaluate changes in intra-epidermal nerve fibre (IENF) density and mitochondrial DNA (mtDNA) copies/cell among subjects treated with 3000 mg ALC daily., Methods: Punch skin biopsies were examined at baseline and after 24 weeks of therapy. Participants reported neuropathic symptoms using the Gracely Pain Intensity Score. Neurological examinations were completed., Results: Twenty-one subjects completed the study. ALC was generally well tolerated. The IENF density did not change in cases completing 24 weeks of ALC therapy, with median (90% confidence interval) IENF changes of -1.70 (-3.50, infinity) (P=0.98) and 2.15 (-0.10, infinity) (P=0.11) for the distal leg and proximal thigh, respectively. Fat mtDNA copies/cell did not change with therapy. Improvements in neuropathic pain (P<0.01), paresthesias (P=0.01), and symptoms of numbness (P<0.01) were noted. Similarly, improvement was noted on the Gracely Pain Intensity Score., Conclusions: ALC therapy coincided with improvements in subjective measures of pain in this open-label single-arm study. However, changes were not observed in objective measures of IENF density or mtDNA levels, providing little objective support for use of ALC in this setting.

Background: Current disease-modifying drugs (DMDs) have positively affected the treatment of relapsing-remitting multiple sclerosis (RRMS); however, the requirement for long-term injections imposes a burden on patients and may lead to reduced adherence in some cases. Furthermore, not all patients respond adequately to current DMDs, suggesting that certain patients require different therapeutic approaches. Therefore, alternative MS treatments with less invasive routes of administration and new modes of action are needed to expand the current treatment repertoire, increase patient satisfaction and adherence, and thereby improve efficacy., Discussion: This review discusses the current unmet need for an orally administered treatment for RRMS, including potential benefits of this route of administration, and implications for improved treatment outcomes. Oral drugs that are currently in Phase II/III clinical development are discussed.

Port-wine stains are congenital vascular malformations affecting 0.3% to 0.5% of infants. Dermatitis occurring exclusively or most severely within port-wine stains has been described in the literature. Traditionally, topical corticosteroid therapy has been used for the treatment of dermatitis, while pulseddye laser treatment is considered a safe and effective means of lightening the appearance of congenital port-wine stains. To describe the development of port-wine stain-associated dermatitis as well as a rational treatment approach to these patients, we studied three children with facial, limb, or truncal port-wine stains who developed dermatitis within the congenital vascular malformation either prior to or during treatment with pulseddye laser. Laser therapy of dermatitis-affected areas was subsequently deferred pending resolution of the dermatitis with topical corticosteroid or topical calcineurin inhibitor treatment. While pulseddye laser therapy is an effective means of lightening port-wine stains and achieving lasting resolution of any associated dermatitis, this therapy to dermatitis-affected areas should be postponed until the inflammation resolves to minimize the risk of laser-associated adverse effects.

Congenital midline nasal masses are rare anomalies, of which dermoid cysts are the most common type. Nasal dermoids have been classically described in the literature as pale, flesh-colored, pearly, or erythematous nodules or masses. The presentation of a nasal dermoid as an ill-defined, yellowish plaques has not been emphasized previously. We describe three infants who presented with congenital, ill-defined, yellowish plaques of the midline nasal dorsum. We attribute the yellowish color to the relative prominence of sebaceous glands within the cyst, given the nasal location. Recognition of this unusual presentation of a nasal dermoid is important in order that appropriate imaging and intervention be undertaken.

Pyogenic granuloma, also known as lobular capillary hemangioma, is a common, benign, acquired, vascular neoplasm of the skin and mucous membranes characterized by an erythematous, dome-shaped papule that bleeds easily. This is a retrospective study of 128 children with pyogenic granuloma treated at the Johns Hopkins pediatric dermatology clinic between 1991 and 2001. This study was undertaken to analyze the clinical characteristics, natural history, treatment options, recurrence risk, and outcome of this entity in children. The majority of the patients had uncomplicated pyogenic granuloma and were treated with a single shave excision and electrocautery, with no recurrences and good cosmetic results.

A retrospective analysis of 25 infants and young children with anogenital warts was performed by chart review and telephone interview. Fifteen of 17 patients treated with podofilox 0.5% gel and 6 of 8 patients treated with imiquimod 5% cream improved or cleared with therapy. Only one patient stopped treatment because of irritation. Our experience suggests that these agents can be used safely and effectively in young children. Controlled prospective studies should be undertaken to further evaluate the use of podofilox and imiquimod in the treatment of symptomatic anogenital warts in children.

Establishment of diagnostic criteria for atopic dermatitis has been a subject of controversy and frequent reevaluation. The diagnostic criteria of Hanifin and Rajka are those most frequently cited. In order to fit the diagnosis, a patient must demonstrate three major criteria plus four or more minor criteria. Although individually the minor criteria are not diagnostic, their presence suggests the possibility of atopic dermatitis. Recently we evaluated several children who developed prominent periumbilical papules as a major component of their atopic dermatitis. This finding, while not present in all children with atopic dermatitis, can provide a specific clue to diagnosis and should be considered as a new minor criterion for atopic dermatitis in children.

Generalized chronic cutaneous lupus including lupus panniculitis in childhood is rare and usually occurs in the setting of genetic complement deficiencies. The association with antiphospholipid syndrome is even more rare. We report a 13-year-old girl with extensive lupus panniculitis since the age of 8 months and no evidence of complement deficiency. She recently developed antiphospholipid syndrome characterized by anticardiolipin antibodies and digital necrosis.

The classic description of erythema marginatum is of a few asymptomatic erythematous patches or plaques with a characteristic central clearing which may coalesce and develop a polycyclic configuration. We report a boy with a urticarial eruption without the classic lesions of erythema marginatum in whom the diagnosis of rheumatic fever was subsequently made. Histology of the urticarial lesions revealed a mixed, superficial, perivascular infiltrate with prominent eosinophils. Rheumatic fever should be considered in children with fever and urticaria-like eruptions even in the absence of the classically described erythema marginatum.

Lichen striatus is a common childhood eruption, but only rare reports link cutaneous manifestations and onychodystrophy. We report a case of lichen striatus and onychodystrophy in a 12-year-old girl, only the eighth such patient in the dermatologic literature. Nail changes may precede the rash of lichen striatus and should be considered in the differential diagnosis of isolated nail dystrophy in children.

This study was conducted to determine the behavioral responses and self-concepts of young children with self-limited but transiently disfiguring capillary hemangiomas involving the head and neck. Nineteen children with hemangiomas, age 3 to 5 years, and their parents were compared with an age-matched control group without lesions. Responses to a parental checklist, informal interview, and self-concept test showed few differences between young children with hemangiomas and those without this neoplasm.

An 8-year-old girl had Crohn's disease of the vulva 16 months before the onset of intestinal symptoms. At the time of diagnosis she had no evidence of systemic disease. Cutaneous and intestinal lesions responded rapidly to corticosteroids and metronidazole. Crohn's disease must be considered in the differential diagnosis of nontender, red, edematous plaques of the genital area.

Although xanthogranulomas are frequently encountered by pediatricians and dermatologists, data on the course of this tumor are restricted to several series with limited follow-up. We report on our experience with 64 patients whom we were able to identify from the surgical files. Our data support the currently held view that xanthogranulomas are generally benign, self-limited lesions. They may persist or continue to erupt for years, however, particularly in individuals who develop the first lesion after age 20 years.
