Background Upper facial port-wine stain (PWS) is a feature of Sturge-Weber syndrome (SWS). Recent studies suggest that the distribution of the PWS corresponds to genetic mosaicism rather than to trigeminal nerve impairment. Objectives We sought to refine the cutaneous distribution of upper facial PWS at risk for SWS. Methods This was a prospective multicenter study of consecutive cases of upper facial PWS larger than 1 cm² located in the ophthalmic division of trigeminal nerve distribution in infants aged less than 1 year, seen in 8 French pediatric dermatology departments between 2006 and 2012. Clinical data, magnetic resonance imaging, and photographs were systematically collected and studied. PWS were classified into 6 distinct patterns. Results In all, 66 patients were included. Eleven presented with SWS (magnetic resonance imaging signs and seizure). Four additional infants had suspected SWS without neurologic manifestations. Hemifacial (odds ratio 7.7, P = .003) and median (odds ratio 17.08, P = .008) PWS patterns were found to be at high risk for SWS. A nonmedian linear pattern was not associated with SWS. Limitations Small number of patients translated to limited power of the study. Conclusions Specific PWS distribution patterns are associated with an increased risk of SWS. These PWS patterns conform to areas of somatic mosaicism. Terminology stipulating ophthalmic division of trigeminal nerve territory involvement in SWS should be abandoned.

International audience; BACKGROUND:Hair collar sign (HCS) and hair tuft of the scalp (HTS) are cutaneous signs of an underlying neuroectodermal defect, but most available data are based on case reports.OBJECTIVE:We sought to define the clinical spectrum of HCS and HTS, clarify the risk for underlying neurovascular anomalies, and provide imaging recommendations.METHODS:A 10-year multicenter retrospective and prospective analysis of clinical, radiologic, and histopathologic features of HCS and HTS in pediatric patients was performed.RESULTS:Of the 78 patients included in the study, 56 underwent cranial and brain imaging. Twenty-three of the 56 patients (41%) had abnormal findings, including the following: (1) cranial/bone defect (30.4%), with direct communication with the central nervous system in 28.6%; (2) venous malformations (25%); or (3) central nervous system abnormalities (12.5%). Meningeal heterotopia in 34.6% (9/26) was the most common neuroectodermal association. Sinus pericranii, paraganglioma, and combined nevus were also identified.LIMITATIONS:The partial retrospective design and predominant recruitment from the dermatology department are limitations of this study.CONCLUSIONS:Infants with HCS or HTS are at high risk for underlying neurovascular anomalies. Magnetic resonance imaging scans should be performed in order to refer the infant to the appropriate specialist for management.Copyright © 2016 American Academy of Dermatology, Inc.

Background: Inherited ichthyoses belong to a large, clinically and etiologically heterogeneous group of mendelian disorders of cornification; typically involving the entire integument. Over the recent years, much progress has been made defining their molecular causes. However, there is no internationally accepted classification and terminology. Objective: We sought to establish a consensus for the nomenclature and classification of inherited ichthyoses. Methods: The classification project started at the First World Conference on Ichthyosis in 2007. A large international network of expert clinicians, skin pathologists, and geneticists entertained an interactive dialogue over 2 years, eventually leading to the First Ichthyosis Consensus Conference held in Soreze, France, on January 23 and 24, 2009, where subcommittees on different issues proposed terminology that was debated until consensus was reached. Results: It was agreed that currently the nosology should remain clinically based. "Syndromic" versus "nonsyndromic" forms provide a useful major subdivision. Several clinical terms and controversial disease names have been redefined: eg, the group caused by keratin mutations is referred to by the umbrella term, "keratinopathic ichthyosis"-under which are included epidermolytic ichthyosis, superficial epidermolytic ichthyosis, and ichthyosis Curth-Macklin. "Autosomal recessive congenital ichthyosis" is proposed as an umbrella term for the harlequin ichthyosis, lamellar ichthyosis, and the congenital ichthyosiform erythroderma group. Limitations: As more becomes known about these diseases in the future, modifications will be needed. Conclusion: We have achieved an international consensus for the classification of inherited ichthyosis that should be useful for all clinicians and can serve as reference point for future research.

Background Vitiligo often starts in childhood. It is traditionally divided into segmental vitiligo and nonsegmental vitiligo. There are limited data regarding the clinical characteristics of both forms and no comparative study has been performed. Objective To compare the clinical features of nonsegmental and segmental vitiligo in children. Patients and Methods We performed a prospective observational study. Consecutive children with vitiligo seen between October 2005 and December 2007 in the 11 French Departments of Pediatric Dermatology were included. A standardized evaluation was completed after total body clinical examination. A second examination was performed 1 year after inclusion. The clinical characteristics of segmental vitiligo and nonsegmental vitiligo were compared. Results A total of 114 children with vitiligo were included. Compared with segmental vitiligo, nonsegmental vitiligo was associated with a higher number of lesions (more than 5 patches in 65.17% vs 20% of patients, P P ± .01). A higher incidence of the Koebner phenomenon (47.19% vs 24%, P = .03), and more frequent progression of the disease (23.29% vs 5.56%, P = .043) were found in nonsegmental vitiligo. Hyperpigmented rims surrounding patches of vitiligo were only seen in nonsegmental vitiligo (8.99% vs 0% ( P = .007). Sixty-four children (56%) had laboratory investigations performed; thyroid abnormalities were found only in nonsegmental vitiligo (11.23% vs 0%, P = .0001). Limitations Not all patients underwent laboratory investigations. Conclusions Segmental and nonsegmental types of vitiligo have distinguishing clinical characteristics.

Background Ulcerated infantile hemangiomas (IH) are a therapeutic challenge. Propranolol, a nonselective beta-blocker, was recently introduced as a novel treatment for IH. Objective To evaluate our experience of propranolol in the management of ulcerated IH. Methods A national, multicenter, retrospective, observational study was conducted. Data were collected from the medical charts of patients treated from 2008 to 2009 and supplemented by information obtained from parents during targeted telephone interviews. Results Thirty-three infants with propranolol-treated ulcerated IH were included. The average time to complete ulceration healing was 4.3 weeks in 30 of 33 patients and was significantly faster for head-and-neck locations ( P = .0354). The mean time to complete pain control was 14.5 days. Parents rated treatment as very effective for 27 of 31 patients and very well tolerated for 29 of 31 cases. Limitations This was a retrospective uncontrolled study. Conclusion Propranolol appears to be an effective and well-tolerated treatment for ulcerated IH.
