ABSTRACT
BACKGROUND: Sturge-Weber syndrome (SWS) is a rare congenital neurocutaneous disorder characterized by the simultaneous presence of both cutaneous and extracutaneous capillary malformations. SWS usually presents as a facial port-wine birthmark, with a varying presence of leptomeningeal capillary malformations and ocular vascular abnormalities. The latter may lead to significant neurological and ocular morbidity such as epilepsy and glaucoma. SWS is most often caused by a somatic mutation involving the G protein subunit alpha Q or G protein subunit alpha 11 gene causing various alterations in downstream signaling pathways. We specifically conducted a comprehensive review focusing on the current knowledge of clinical practices, the latest pathophysiological insights, and the potential novel therapeutic avenues they provide. DATA SOURCES: A narrative, non-systematic review of the literature was conducted, combining expert opinion with a balanced review of the available literature. A search of PubMed, Google Scholar and Embase was conducted, using keywords "Sturge-Weber Syndrome" OR "SWS", "Capillary malformations", "G protein subunit alpha 11" OR "G protein subunit alpha Q". RESULTS: One of the hallmark features of SWS is the presence of a port-wine birthmark at birth, and forehead involvement is most indicative for SWS. The most common ocular manifestations of SWS are glaucoma and choroidal hemangioma. Glaucoma presents in either in infancy (0-3 years of age) or later in life. Neurological complications are common in SWS, occurring in about 70%-80% of patients, with seizures being the most common one. SWS significantly impacts the quality of life for patients and their families, and requires a multidisciplinary approach for diagnosis and treatment. Currently, no disease-modifying therapies exist, and treatment is mostly focused on symptoms or complications as they arise. CONCLUSIONS: SWS remains a complex and heterogeneous disorder. Further research is needed to optimize diagnostic and therapeutic strategies, and to translate insights from molecular pathogenesis to clinical practice.

A 6-year-old boy with multiple capillary malformations of the port-wine birthmark (PWB) type on the right leg since birth presented with a varicose vein and segmental overgrowth of the affected leg. Genetic testing on affected skin confirmed the presence of a somatic novel pathogenic HRAS 30 bp in-frame duplication/insertion in the switch II domain. This case illustrates the phenotypic overlap of different genotypes and shows that somatic HRAS pathogenic variants, especially in-frame duplications/insertions, must be added to the list of the underlying causes in capillary malformations.

Acral lesions are well-known physical findings in various infectious disorders. Although they are often overlooked, they can be the key to the diagnosis of the underlying disease. Considering this, we present an overview of various infectious causes of acral lesions in childhood. In addition, we discuss their characteristic presentation, evolution, and appropriate treatment. To our knowledge, this is the first review covering viral, bacterial and mycotic causes.

In this study, the care for children with a severe chronic skin disease in our national expert center of pediatric dermatology was evaluated. Patients and their parents were questioned by using existing questionnaires: 50 pediatric patients completed the modified "my positive health" questionnaire of Huber and 51 parents completed Pelentsov parental needs scale. Nineteen involved professionals answered a questionnaire with open boxes. Parents of children with a variety of chronic skin diseases and young adult patients were interviewed to find out what an optimal approach would look like according to them. Children with a severe chronic and/or congenital skin disorder score high on the "my positive health" questionnaire, indicating they are able to adapt and self-manage. Their highest median score was measured for the dimension "quality of life." Their parents expect improvement of "working with health care professionals," more specifically they want them to adopt a more holistic approach throughout the patient's life. Structured interviews showed they expect that a multidisciplinary team of care providers determine together with the patient and its family-in advance-which care is needed, at what time and by whom. The interviewed professionals indicated adoption of a holistic multidisciplinary approach as the single largest improvement to achieve better care.Conclusion: Although these children with a severe chronic and/or congenital skin disease were able to adapt and self-manage, they need a more personalized integrative multidisciplinary and systematic transmural approach covering all aspects of life during their lifetime. What is Known: ⢠Severe skin disorders affect the child and its family in several ways. In our expert center, we try to optimize the care for these children through a multidisciplinary approach. What is New: ⢠To our knowledge, no English publication describes the requirements for good care for pediatric patients with severe chronic skin disorders and how to optimize this care. We evaluated the health status of children with severe chronic skin disorders and the strengths and weaknesses of past and current care by questioning these children, their parents, adult patients, and involved professionals.

Mastocytosis refers to a heterogeneous group of clinical disorders characterized by an abnormal accumulation of mast cells (MCs) in various tissues. The skin is the organ most frequently involved, but all organs may be affected. The clinical signs and symptoms are produced by the functional effects of mast cell-derived mediators and the anatomical distribution of the mast cells. The 2008 WHO-classification defines 7 categories of mastocytosis. Skin disease, with or without systemic involvement, is by far the most common form of childhood mastocytosis. Measurement of serum tryptase is important in the diagnostic algorithm of pediatric mastocytosis. In children with tryptase <20 ng/mL, the diagnosis of cutaneous mastocytosis (CM) may be decided upon without bone marrow examination (BME), unless other signs of SM are present. If the baseline tryptase level exceeds 100 ng/mL, a BME should be considered regardless of age. If the serum tryptase is 20-100 ng/mL in children without other signs of SM, the provisional diagnosis "mastocytosis in the skin" (MIS) can be established and monitored until puberty. If MIS remains present after puberty, a BME should be performed. In adult-onset mastocytosis a complete staging and application of the systemic mastocytosis criteria should always be performed. Treatment is mainly directed at alleviation of symptoms. As c-kit mutations prove to be very important in the pathogenesis of mastocytosis, targeted therapies using kit inhibitors may evolve as important future therapeutic options.
