A patient with extensive multisystem overgrowth caused by a somatic gain of function PIK3CA-mutation is described. This case is an example of the clinical diversity of the PIK3CA-Related Overgrowth Spectrum (PROS) as the patient had overlapping features of Congenital Lipomatous Overgrowth Vascular malformations Epidermal nevi and Skeletal abnormalities (CLOVES) syndrome and Megalencephaly-Capillary malformation Polymicrogyria (MCAP) syndrome and underlines the utility of this umbrella term., (© 2018 Wiley Periodicals, Inc.)

Purpose: The incidence of infantile-onset secondary glaucoma associated with periocular cutaneous vascular malformations is high and the outcomes of these glaucomatous eyes have anecdotally been poor. The purpose of this study was to determine the anatomic and visual outcomes of affected eyes., Design: Retrospective case series., Methods: Consecutive patients with early-onset (younger than 36 months of age) glaucoma associated with cutaneous vascular malformations from 1995‒2015 were included., Results: Seventeen eyes of 13 patients with Sturge-Weber syndrome (SW, n = 10), Klippel-Trenaunay-Weber syndrome (KTW, n = 1), cutis marmorata telangiectatica congenita (CMTC, n = 1), and phakomatosis pigmentovascularis (PPV, n = 1) were included. Three SW and 1 KTW patient had bilateral glaucoma. At presentation, mean age was 6.5 ± 9.1 months and mean intraocular pressure was 27.2 ± 6.13 mm Hg. The average number of surgical procedures per eye increased from 1.0 ± 0.5 (range, 0‒2) at less than 5 years' follow-up (9 eyes) to 3.5 ± 2.3 (range, 1‒7) with at least 5 years' follow-up (8 eyes). Visual acuity was better than or equal to 20/70 in 2 of 6 eyes (33%) with less than 5 years' follow-up and in 3 of 7 eyes (43%) with at least 5 years' follow-up. Additionally, a higher number of baseline risk factors correlated with poorer visual outcome., Conclusions: After a mean follow-up of 6.6 years, visual outcome in infantile-onset secondary glaucoma associated with cutaneous periocular vascular malformation is guarded. Increased numbers of baseline risk factors and procedures are associated with poorer vision., (Copyright 2017 Asia-Pacific Academy of Ophthalmology.)

A 39-week-old male newborn presented at birth with atrophic erythematous and purpuric skin lesions, in a typical right-sided segmental distribution. Lesions were persistent and unaffected by rewarming in the postpartum period. Postnatal echocardiogram showed a predominance of the right cavities and an upper atrial septal defect. Cerebral and abdominal ultrasound were normal along with ophthalmological examination. On follow-up, lower limbs asymmetry was noted. The right lower limb was shorter in length and had a smaller diameter. At 6 months, the right lower limb was 1.5 cm shorter than the left, most likely related to nutritive vessels malformations. The discrepancy was even more pronounced at the age of 9 months. This leg-length asymmetry can lead to severe functional limitations in the future., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Background: CLOVES (congenital lipomatous overgrowth, vascular malformations, epidermal nevi, and skeletal anomalies) syndrome is associated with regional bony and/or soft tissue overgrowth, capillary malformation, and an increased risk for Wilms tumor., Objective: To evaluate the frequency of Wilms tumor in patients with 2 similar conditions: diffuse capillary malformation with overgrowth (DCMO) and macrocephaly-capillary malformation (M-CM)., Methods: Culling our Vascular Anomalies Center database, we retrospectively reviewed patients in whom DCMO and M-CM had been diagnosed and who were evaluated between 1998 and 2016 for possible development of Wilms tumor. Patients younger than 8 years of age at their last visit and not seen in more than 2 years were contacted for follow-up., Results: The study comprised 89 patients: 67 with DCMO, 17 with M-CM, and 5 with an indeterminate diagnosis. No case of Wilms tumor was found in these groups., Limitations: Some patients were younger than 8 years of age at last follow-up visit and the sample size was small., Conclusion: Patients with DCMO do not appear to be at increased risk for Wilms tumor. Screening is probably unnecessary in DCMO unless there is associated hemihypertrophy. Although there were no cases in our cohort, there are 2 reports of M-CM associated with Wilms tumor in the literature., (Copyright © 2017 American Academy of Dermatology, Inc.

We present a unique case of 3 vascular malformations-Sturge-Weber syndrome (SWS), facial infantile hemangioma (IH), and cutis marmorata telangiectatica congenita (CMTC)-with dermatologic manifestations presenting in the same patient. This case highlights the possibility of occurrence of multiple vascular malformations in the same patient; the potential role of epigenetic factors; and the importance of a multidisciplinary approach to diagnose, treat, and manage this complicated interplay of vascular abnormalities to achieve the best outcome.

Megalencephaly-Capillary Malformation Polymicrogyria (M-CAP) is a rare genetic disorder characterized by a spectrum of anomalies including macrocephaly and neurovascular malformations. Although developmental delays have been identified, research is devoid of neuropsychological data. This case report presents the neuropsychological profile of a 7-year-old, identified with M-CAP. Neuropsychological evaluation was completed subsequent to medical diagnosis. Reports from both parents and teachers included cognitive regression; specifically in the recall of learned material, reading, and information sequencing. Direct testing revealed a WISC-IV GAI at <1 st percentile, a diverse range of scores across the battery, and a splinter skill strength of average to above on visual memory tests. Performance included below grade level reading and writing, reduced adaptive functioning, and reported executive dysfunction. Her strong visual memory skills were recommended as a medium to enhance learning. Neurocognitive deficits revealed diverse, multisystem and multifocal impairments. The neuropsychological evaluation also showed significant decline from the previous evaluation and prompted a neurologic consult and corrective surgical procedure.

Parenteral prostacyclin is the most-effective therapy for patients with pulmonary arterial hypertension. Administration is complex, and administration errors are potentially life threatening. Hospital policies to minimize the risk to patients are necessary, but their effectiveness has not been well studied. We quantified the adverse event incident rate per at-risk patient day in a tertiary care hospital with an established parenteral prostacyclin policy. Patients on parenteral prostacyclin including new initiations from January 2003 to January 2013 were identified, encompassing 386 discrete admissions. Reports of adverse events were obtained from the inpatient risk feedback-reporting process and detailed chart review. Policy-divergent events were analyzed both categorically and by the degree of severity. Overall, 153 total policy-divergent events were identified. Data analysis indicated an incident rate of 45.9 per 1,000 patient days. In total, 21 of 153 potential errors reached the patient, translating to an incident rate of 6.3 per 1,000 patient days. Incident rate for "serious symptomatic" or "catastrophic" policy-divergent events was 3.3 per 1,000 patient days. Even with specific prostacyclin training and administration policy, there remains a small risk of adverse events in hospitalized pulmonary hypertension patients receiving parenteral prostacyclin.

Hereditary hemorrhagic telangiectasia (HHT) is a dominantly inherited genetic vascular disorder with an estimated prevalence of 1 in 6,000, characterized by recurrent epistaxis, cutaneous telangiectasia, and arteriovenous malformations (AVMs) that affect many organs including the lungs, gastrointestinal tract, liver, and brain. Its diagnosis is based on the Curaçao criteria, and is considered definite if at least 3 of the 4 following criteria are fulfilled: (1) spontaneous and recurrent epistaxis, (2) telangiectasia, (3) a family history, and (4) pulmonary, liver, cerebral, spinal, or gastrointestinal AVMs. The focus of this review is on delineating how HHT affects the lung., (© 2017 S.

Glomus tumors are rare hamartomas that originate from the glomus body. These tumors can be divided into solitary and multiple, the latter also known as glomangioma. We report the case of two patients with a rare variety of glomangioma called congenital plaque-like glomangioma. It presents as numerous red to bluish compressible papules, that increase in size in proportion with the weight and height growth of the child. Diagnostic confirmation is with histopathology and the treatment is surgical.

Cutis marmorata telangiectatica congenita (CMTC) is a sporadic congenital vascular anomaly usually presents at birth as a localized or generalized reticulated, erythema and telangiectasia. The pathogenesis of CMTC is unknown. Additional anomalies have been frequently reported in association with CMTC. This article describes the characteristics of the clinical presentations in a series of 7 children with CMTC in HRH Princess Maha Chakri Sirindhorn Medical Center, Srinakharinwirot University, Thailand. Both genders were almost equally affected (3 male/4 female). The lower limbs were involved in 7 patients (100%), the trunk in 3 patients (42.9%), and the upper limbs in 1 patient (14.3%). There were 2 patients (28.6%) who presented with the involvement of both trunk and limbs. The mean of the body surface area involved was 17% (2-50). Asymmetry of affected limbs were found in 2 patients (28.6%). On follow-up, improvement of reticulated lesions was noted in all patients. The prognosis of uncomplicated cases is good. No specific treatment is needed. The skin lesions usually disappear gradually.

Vascular stains are a common reason for consultation in pediatric dermatology clinics. Although vascular stains include all vascular malformations, the term is most often used to refer to capillary malformations, but capillary malformations include a wide range of vascular stains with different clinical features, prognoses, and associated findings. The discovery of several mutations in various capillary malformations and associated syndromes has reinforced these differences, but clinical recognition of these different types of capillary vascular stains is sometimes difficult, and the multitude of classifications and confusing nomenclature often hamper the correct diagnosis and management. From our own experience and a review of the most relevant literature on this topic, we propose categorizing patients with capillary vascular stains into seven major clinical patterns: nevus simplex, port-wine stain, reticulated capillary malformation, geographic capillary malformation, capillary malformation-arteriovenous malformation (CM-AVM), cutis marmorata telangiectatica congenita, and telangiectasia. We also discuss the differential diagnosis of vascular stains as well as other conditions that can closely resemble capillary malformations and thus may potentially be misdiagnosed., (© 2016 Wiley Periodicals, Inc.)

The authors present the case of a child with megalencephaly-capillary malformation syndrome who developed a rapidly progressive holocord syringomyelia that was treated surgically. A 3-year-old boy with megalencephaly-capillary malformation-polymicrogyria (MCAP) syndrome presented with several months of right leg weakness, worsening scoliosis, and increased seizures. An MRI study of the brain demonstrated a Chiari I malformation and massively dilated syringomyelia extending from C-2 to the conus medullaris. The patient underwent an urgent suboccipital craniectomy with C1-3 laminectomies to relieve the CSF outflow obstruction with significant clinical improvement. Surgery was complicated by bleeding from intracranial vascular malformations. This report describes a very rapidly developing, massive holocord syringomyelia related to CSF obstruction due to an unusual congenital brain malformation and associated vascular overgrowth at the site. Serial, premorbid MRI studies demonstrated the very rapid progression from no Chiari malformation, to progressively greater cerebellar tonsillar herniation, to holocord syrinx. This complication has never been reported in MCAP syndrome and should be considered in any affected MCAP patient with a progressive neurological decline, even if previous spine imaging findings were normal. Surgical complications due to hemorrhage also need to be considered in this vascular brain malformation.

The megalencephaly capillary malformation syndrome (MCAP, OMIM 602501) is known to be associated with mosaic mutations in PIK3CA occurring during embryogenesis. Standard sequencing technologies are relatively poor at indentifying sequence changes that only affect a small percentage of cells, and the mutations are frequently not identified in lymphocyte DNA, with biopsies of the affected tissues often being required to detect mosaic mutations. Such invasive procedures are not always acceptable to parents. We describe the case of a patient in whom we were able to confirm a causative PIK3CA mutation, first found thorugh next-generation sequencing, in several tissue types including a secondary tooth. As part of this work, we were also able to begin validating dental tissue for potential use in genetic testing, as we achieved excellent DNA yields with minimal effort, even from deciduous teeth shed some years earlier.

Unlabelled: Vascular anomalies and related conditions cause overgrowth of tissues. The purpose of this study was to determine the efficacy and safety of liposuction techniques for pediatric overgrowth diseases. Patients treated between 2007 and 2015 who had follow-up were reviewed. Seventeen patients were included; the median age was 12.7 years. The causes of overgrowth included infiltrating lipomatosis (n = 7), capillary malformation (n = 6), hemihypertrophy (n = 1), infantile hemangioma (n = 1), lipedema (n = 1), and macrocephaly-capillary malformation (n = 1). Forty-seven percent had enlargement of an extremity, 41 percent had facial hypertrophy, and 12 percent had expansion of the trunk. All subjects had a reduction in the size of the overgrown area and improved quality of life. Suction-assisted tissue removal is an effective technique for reducing the volume of the subcutaneous compartment for patients with pediatric overgrowth diseases., Clinical Question/level of Evidence: Therapeutic, IV.

Phacomatosis pigmentovascularis (PPV) is a rare genodermatosis characterized by the co-existence of an extensive vascular and a pigmentary nevus with or without extracutaneous manifestations. We report two such rare cases. The first is a 3-year-old boy exhibiting a rare association of cutis marmorata telangiectatica congenita with aberrant dermal melanocytosis along with hypospadias and melanosis oculi (traditionally classified as PPV type Vb or phacomatosis cesiomarmorata - Happle's classification). The other patient is a 5-year-old boy with Sturge-Weber syndrome, Klippel-Trenaunay syndrome, aplasia of iliac, femoral, and popliteal veins and congenital heart disease, associated with aberrant dermal melanocytosis and melanosis oculi (also classified as PPV type IIb or phacomatosis cesioflammea). These sporadic cases display a unique constellation of additional, previously unreported systemic associations, which will further expand the clinical spectrum of phacomatosis pigmentovascularis.

Cutis Marmorata Telangiectatica Congenita (CMTC) is a congenital localized or generalized vascular anomaly, usually sporadic in occurrence. It can be associated with other cutaneous or systemic manifestations. About 300 cases have been reported. The molecular etiology remains largely unknown. The main purpose of this study is to delineate the molecular basis for a syndromic CMTC phenotype in a consanguineous Saudi family. Clinical phenotyping including detailed neurological imaging, followed by autozygosity mapping and trio whole exome sequencing (WES) are also studied. We have identified a homozygous truncating mutation in ARL6IP6 as the likely cause of a syndromic form of CMTC associated with major dysmorphism, developmental delay, transient ischemic attacks and cerebral vascular malformations. This gene was previously implicated by genome wide association study (GWAS) as a susceptibility locus to ischemic stroke in young adults. We identify ARL6IP6 as a novel candidate gene for a syndromic form of CMTC. This suggests that ischemic stroke or transient ischemic attacks (TIA) may represent, at least in some cases, the mild end of a phenotypic spectrum that has at its severe end autosomal recessive CMTC. This finding contributes to a growing appreciation of the continuum of Mendelian and common complex diseases.

Phacomatosis pigmentovascularis is a rare genodermatosis characterized by the combination of an extensive pigmentary nevus with a widespread vascular nevus. The coexistence of aberrant dermal melanocytosis and cutis marmorata telangiectatica congenita has been termed phacomatosis pigmentovascularis type V or phacomatosis cesiomarmorata. Phacomatosis pigmentovascularis type V was first described in a 3-month-old boy in 2000. Since then, there have been a further seven cases published in the literature.

Phacomatosis pigmentovascularis is a rare, congenital condition characterized by a combination of cutaneous melanocytic lesions and vascular malformation. We discuss an entirely unique case of Phacomatosis pigmentovascularis with nevus of Ota, extensive Mongolian spot, nevus flammeus, nevus anemicus and cutis marmorata telangiectatica congenita, which may represent a heretofore undescribed variant of phacomatosis pigmentovascularis.

Megalencephaly-capillary malformation (MCAP) syndrome is an overgrowth syndrome that is diagnosed by clinical criteria. Recently, somatic and germline variants in genes that are involved in the PI3K-AKT pathway (AKT3, PIK3R2 and PIK3CA) have been described to be associated with MCAP and/or other related megalencephaly syndromes. We performed trio-exome sequencing in a 6-year-old boy and his healthy parents. Clinical features were macrocephaly, cutis marmorata, angiomata, asymmetric overgrowth, developmental delay, discrete midline facial nevus flammeus, toe syndactyly and postaxial polydactyly--thus, clearly an MCAP phenotype. Exome sequencing revealed a pathogenic de novo germline variant in the PTPN11 gene (c.1529A>G; p.(Gln510Arg)), which has so far been associated with Noonan, as well as LEOPARD syndrome. Whole-exome sequencing (>100 × coverage) did not reveal any alteration in the known megalencephaly genes. However, ultra-deep sequencing results from saliva (>1000 × coverage) revealed a 22% mosaic variant in PIK3CA (c.2740G>A; p.(Gly914Arg)). To our knowledge, this report is the first description of a PTPN11 germline variant in an MCAP patient. Data from experimental studies show a complex interaction of SHP2 (gene product of PTPN11) and the PI3K-AKT pathway. We hypothesize that certain PTPN11 germline variants might drive toward additional second-hit alterations.

We report the case of a boy with cutis marmorata telangiectatica congenita, strokelike episodes, and a pinpoint stenosis of the left internal carotid artery. To our knowledge, this is the first report of a stenosis of an intracranial artery in a patient with cutis marmorata telangiectatica congenita., (© The Author(s) 2014.)

Hereditary benign telangiectasia (HBT) is a very uncommon, genetically inherited, benign skin disorder, identified by widespread cutaneous telangiectasias. Herein, we present two sporadic cases of HBT that were admitted to the dermatology clinic for multiple punctate telangiectasias surrounded by anemic halos, favoring sun-exposed areas. These cases had no mucosal or visceral involvement and exhibited no family history of the disorder. The phenotypes of HBT are clinically and genetically heterogeneous. More clinical experience and genetic analyses are needed to understand the basis for the genetic heterogeneity and to determine genotype-phenotype correlations. We aimed to emphasize the hereditary and clinical heterogeneity of HBT by presenting two cases of HBT with punctate telangiectasias surrounded by anemic halos, with a sporadic occurrence.

Cutis Marmorata Telangiectatica Congenita (CMTC) is a rare, sporadic condition usually present at birth characterized by localized or generalized persistent cutis marmorata, telangiectasia and phlebectasia. We report a preterm female newborn, the third child of non-related caucasian parents, with CMTC at birth who showed typical cutaneous features and monolateral congenital glaucoma. The pathogenesis of this disorder is unknown and the cause is probably multifactorial. Teratogens and autosomal dominant mode of inheritance with incomplete penetrance have been considered as etiological factors. Prognosis, in uncomplicated cases, is good.

Many practitioners assume every vascular lesion is a hemangioma; then tell parents not to worry, because hemangiomas "go away" after they grow. In fact, over the past three decades, advances in the stratification of vascular lesions, identification of clinical associations and syndromic vascular anomalies, and the discovery of germline and somatic mutations accompanying certain vascular anomalies have broadened our understanding. Concomitantly, the evaluation and management of vascular anomalies have become more sophisticated, and a laissez-faire approach is often inadequate. This paper focuses on hemangiomas of infancy and is divided into two sections, Evaluation and Management, both sections including updated references to clinical and basic research and reviews supporting the discussion., (Copyright © 2014 Elsevier Inc.

Most infantile hemangiomas have a spontaneous and uneventful involution and, hence, may be treated expectantly. Others, however, will present some complication along their evolution that may require prompt therapeutic interventions. Ulceration is the most common complication, and amblyopia is frequently associated with periocular tumors. Airways hemangiomas may be life-threatening, and disfigurement can heavily impact the patient's quality of life., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Background: Cutis marmorata telangiectatica congenita (CMTC) is a vascular malformation, diagnosed based on cutaneous manifestations. It is associated with limb length discrepancy (LLD) and asymmetry, but the exact extent of this and its relationship to the site of the cutaneous manifestations have not been delineated., Objectives: To review the orthopaedic problems associated with CMTC, concentrating on the assessment and management of the LLD., Methods: This study is a retrospective analysis of orthopaedic, dermatological and vascular data that were collected prospectively at our tertiary referral centre. We identified 80 patients with an initial diagnosis of CMTC; 57/69 patients with a confirmed diagnosis had lower-limb involvement., Results: An LLD was identified in 51% of cases. The discrepancy was significant (defined as ≥ 2 cm) in nine patients and was confirmed using standing leg-length radiographs. Of these patients, three had epiphysiodesis to correct the discrepancy, and surgery is planned in five others., Conclusions: Limb length discrepancy and asymmetry are common in CMTC; however, this is below the significant threshold in most cases. It is therefore recommended that any discrepancy be initially monitored clinically. This should be followed by standing leg-length radiographs at the age of 10 years (girls) or 12 years (boys), or if the LLD is ≥ 2 cm. If this is confirmed radiologically, orthopaedic referral is advised to consider surgical intervention such as epiphysiodesis., (© 2013 British Association of Dermatologists.)

To our knowledge, there are nine previous reports of patients with congenital scrotal agenesis (CSA), seven of which were bilateral, and unilateral in two, also named as hemiscrotal agenesis (HSA). Here, we report a male infant with the previously undescribed co-occurrence of HSA with cutis marmorata telangiectatica congenita (CMTC), and hydronephrosis due to vesicoureteral reflux, all of them on the left side. CMTC is a segmental vascular malformation usually attributed to mosaicism of a postzygotic mutation, whereas the mechanisms in the CSA involve a failure on the labioscrotal fold (LSF) development due to a localized 5α-reductase deficiency and/or androgen insensitivity. Since the skin with HSA was affected also by CMTC and by the fact that it exhibited lack of response to the topical testosterone treatment, all this suggests to us an androgen insensitivity mosaicism in our patient restricted to the left LSF, because skin with intact androgen receptors normally shows some type of response. Since CSA and/or HSA have been also seen in patients with PHACES, popitleal pterygium syndrome, or as part of a recently proposed familial entity with CSA (or agenesis of labia majora as its female counterpart), developmental delay, visual impairment, and moderate hearing loss, further reports could confirm this manifest genetic heterogeneity, highly evocative of somatic mosaicism in our patient., (© 2013 Wiley Periodicals, Inc.)

Background: Rapidly involuting congenital hemangiomas (RICHs) are rare vascular tumors that have a proliferative phase in utero, present fully grown at birth, and have a fast involution phase after birth. Even rarer cases have completed involution in utero and present at birth as an atrophic plaque with redundant skin., Case Report: We present one case of a RICH that underwent involution in utero and revise the diagnostic and management implications.

Cutis marmorata telangiectatica congenita is a well-characterized cutaneous vascular disorder with variable and rare ocular involvement. It has been reported in association with glaucoma, bilateral congenital retinal detachments, bilateral tractional retinal detachments secondary to proliferative vitreoretinopathy, and retinoblastoma. This case demonstrates novel findings of bilateral peripheral retinal vascular abnormalities and retinal nonperfusion on fluorescein angiography without retinal detachment that have not previously been described in cutis marmorata telangiectatica congenita. Laser photocoagulation was applied to areas of retinal nonperfusion with stability in the retinal pathology at follow-up examination 3 months later., (Copyright 2013, SLACK Incorporated.)

Neonatal lupus is a rare disease caused by the transplacental transfer of maternal autoantibodies to the foetus, characterized by transient clinical manifestations such as cutaneous, haematological, and hepatobiliary events or permanent such as congenital heart block. The typical cutaneous manifestations include erythematous, scaly, annular or arched lesions on the face, with slight central atrophy and photosensitivy, clinically and histologically similar to subacute cutaneous lupus. However, in some cases, the lesions may resemble those in cutis marmorata telangiectatica congenita, although this phenomenon is rare and only eight such cases have been reported to date. We report a case of cutaneous neonatal lupus with atypical lesions on the limbs, which had a reddish-purple marbled appearance, resembling the lesions in cutis marmorata telangiectatica congenita.

Vascular birthmarks can be difficult to diagnose in the perinatal period due to varied growth characteristics and similar initial appearances. Location and type of birthmark can provide signals that extracutaneous involvement may be a concern. This article provides a baseline framework that can help diagnose, define associations and guide workup and treatment in these neonates., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Purpose of Review: To summarize clinically relevant findings in the genetic cause and gene expression of vascular anomalies., Recent Findings: Infantile hemangioma demonstrates familial clustering and is associated with atopic disease. Variable gene expression is seen in infantile hemangioma during proliferation and involution. Capillary malformation may be sporadic or inherited in an autosomal dominant pattern. Capillary malformation-arteriovenous malformation is caused by mutation in RASA1. Some inherited forms of lymphedema are due to mutation in VEGFR3. Venous malformation may be sporadic, paradominant, or autosomal dominant inheritance. Autosomal dominantly inherited forms of venous malformation are due to mutations in TIE2/TEK. Additionally, TIE2 somatic mutations have been identified in about half of sporadic venous malformations., Summary: Multiple genes have been identified causing inherited forms of vascular anomalies including capillary malformations, venous malformations and lymphedema. Variable gene expression of infantile hemangioma during proliferation and involution may offer new therapeutic targets for treatment.

Unlabelled: Macrocephaly-cutis marmorata telangiectatica congenita is a multiple congenital anomaly syndrome first described in 1997 in children with macrocephaly, cutis marmorata telangiectatica congenita, and several other abnormalities. Since 2007, this syndrome has been renamed macrocephaly-capillary malformation., Case Report: The pregnancy was marked by polyhydramnios associated with fetal macrosomia and macrocephaly. Clinical examination of the newborn confirmed overgrowth, macrocephaly, and found skin abnormalities with diffuse marbled skin, filtrum and upper lip vascular anomaly, and several superficial capillary malformations on the chest and abdomen, partial bilateral syndactyly between the 2nd and 3rd toes, and right hemi-hypertrophy of the body. Brain magnetic resonance imaging showed moderate right hemimegalencephaly. Radiological examination of the skeleton showed asymmetry of the limbs. At 8 months, the medical follow-up confirmed the diagnosis and its neurosurgical treatment of hydrocephalus secondary to an Arnold Chiari malformation., Discussion: The patient reported herein presented macrocephaly-capillary malformation syndrome characterized by macrocephaly and more than two of the main reported findings comprising cutis marmorata, superficial vascular anomaly, syndactyly, and body asymmetry. We describe the major components of this multiple malformative syndrome that is rarely reported in the pediatric literature, especially in newborns. This syndrome should be detected early because medical multidisciplinary follow-up is necessary to prevent different complications (neurological, orthopedic, or oncologic)., (Copyright © 2012 Elsevier Masson SAS.

Purpose: This is a report of 2 cases of cutis aplasia and cutis marmorata telangiectasia with associated retinal detachment., Methods: Retrospective case report., Results: Illustration of ophthalmic associations of the rare congenital dermatologic presentations and description of successful treatment with laser photocoagulation., Conclusions: Awareness of the association between retinal detachment and cutis aplasia and cutis marmorata should be acted upon as laser photocoagulation has been shown in this case report to successfully treat the associated retinal detachment.

1.Compare and contrast infantile hemangiomas with other vascular anomalies that may be confused clinically.2.Describe the vascular anomalies classification system according to the International Society for the Study of Vascular Anomalies (ISSVA), highlighting the differences between vascular tumors, such as infantile hemangiomas, and vascular malformations.3.Briefly review associated signs or syndromes found in the context of certain vascular anomalies.Infantile hemangiomas are the most common benign vascular tumor in infancy but may mimic many other types of vascular anomalies. In many cases, the appearance, time of onset, growth pattern, and consistency of infantile hemangiomas make the diagnosis straightforward (see "Pathogenesis of Infantile Hemangiomas" on p. 321). However, many other vascular lesions can appear quite similar to infantile hemangiomas, especially early in life, and at times this makes the correct diagnosis challenging., (Copyright 2012, SLACK Incorporated.)
