Any form of congenital nevus in a child is a cause of parental anxiety. Parents are often worried about the future course of the lesion. Some of these lesions grow in extent with the child's growth and involve other body areas; others grow proportionate to the involved body part, giving an impression of apparent growth of the lesion.

Parkes-Weber syndrome is a congenital vascular disease that comprises capillary, venous, lymphatic, and arteriovenous malformations. Although Parkes-Weber syndrome is a clinically distinct entity with serious complications, it is still frequently misdiagnosed as Klippel-Trenaunay syndrome, which consists of a triad of malformations involving the capillary, venous, and lymphatic vessels, without arteriovenous fistulas. Both syndromes are generally diagnosed with Doppler ultrasound and confirmed by magnetic resonance angiography. Read More

Objective: Patients with Klippel-Trénaunay syndrome (KTS) and congenital lipomatous overgrowth, vascular malformations, epidermal nevi, and spinal/skeletal abnormalities (CLOVES) syndrome have central phlebectasia and enlarged persistent embryonic veins that are often incompetent and prone to thromboembolism. The purpose of the study was to determine the presence of phlebectasia and the incidence of symptomatic pulmonary embolism (PE).
Methods: A retrospective review was conducted of patients referred to the Vascular Anomalies Center at our institution during a 21-year period who were diagnosed with KTS and CLOVES syndrome. Read More

CLOVES syndrome (congenital lipomatous overgrowth, vascular malformations, epidermal naevi, scoliosis/skeletal and spinal syndrome) is a genetic disorder that results from somatic, mosaic gain-of-function mutations of the PIK3CA gene, and belongs to the spectrum of PIK3CA-related overgrowth syndromes (PROS). This rare condition has no specific treatment and a poor survival rate. Here, we describe a postnatal mouse model of PROS/CLOVES that partially recapitulates the human disease, and demonstrate the efficacy of BYL719, an inhibitor of PIK3CA, in preventing and improving organ dysfunction.

Congenital lipomatous overgrowth with vascular malformations, epidermal nevi, and skeletal anomalies (CLOVES) syndrome belongs to the spectrum of overgrowth syndromes caused by postzygotic mosaic activating mutations in PIK3CA. CLOVES syndrome is rare. The diagnosis of CLOVES syndrome relies on clinical presentation and imaging studies, and can be proven by molecular genetics. Read More

Most giant congenital melanocytic nevi (GCMN) exhibit an activating mutation in NRAS. Constitutive activation of the RAS-ERK signaling pathway induces proliferation in nevus cells and plays a pivotal role in melanoma development.

Nevus comedonicus is a rare epidermal abnormality of the pilosebaceous unit, which is congenital in most patients but may also appear early in childhood. It may be localized or have an extensive involvement, the latter showing a unilateral predominance with only a few cases presenting bilaterally. Extensive nevus comedonicus can be associated with musculoskeletal defects, eye and neurological involvement, which constitutes nevus comedonicus syndrome. Read More

The acquired melanocytic nevus is the most common lesion encountered by pediatric pathologists and dermatopathologists in their daily practice. In most cases, there are few difficulties in histopathologic diagnosis. However, it is the acquired melanocytic lesion known as the Spitz nevus, with its intrinsic atypical features which becomes the challenge since it exists along a histopathologic and biologic continuum from the atypical Spitz tumor to spitzoid melanoma.

Postzygotic mutations of the PIK3CA [phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha] gene constitutively activate the PI3K/AKT/mTOR pathway in PIK3CA-related overgrowth spectrum (PROS) patients, causing congenital mosaic tissue overgrowth that even multiple surgeries cannot solve. mTOR inhibitors are empirically tested and given for compassionate use in these patients. PROS patients could be ideal candidates for enrolment in trials with PI3K/AKT pathway inhibitors, considering the "clean" cellular setting in which a unique driver, a PIK3CA mutation, is present.

Background: We present to the attention of the medical, dermatological and oncosurgical community data that serves to indicate the indispensability of optimisation of the algorithm and recommendations for diagnosis and surgical treatment of cutaneous melanoma. These recommendations could be referred to different subgroups of patients in different clinical stages as well as to patients with different initial characterisation (histological morphology) of the primary tumours. One step surgery is not a myth, even more, it could prove to be one of the best solutions for some patient collectives with advanced stages of melanoma. Read More

Blue rubber bleb nevus syndrome (BRBNS) is a rare congenital vascular disease associated with important morbidity and non-insignificant risk of mortality in cases of severe gastrointestinal or neurological involvement. Early diagnosis in the neonatal period can be difficult as very often skin lesions appear progressively during childhood having no correlation with gastrointestinal lesion development. The appearance of one large venous malformation (VM) in the neonatal period has suggested a characteristic finding of this syndrome. Read More

Small pigmented lesions in children can represent a significant diagnostic challenge. If the diagnostic features and therapeutic approach are relatively well established in large and giant nevi, there is still much controversy regarding small and intermediate-sized congenital pigmented lesions that can lead to significant diagnostic challenges, both clinically and dermoscopically, and consequently to difficulty in defining the optimal approach in such cases. Although dermoscopy can be useful in the diagnosis of pigmented lesions, the diversity of clinical and dermoscopic features of pigmented nevi in children usually hinder the differentiation between them and melanoma.

Vascular anomalies are a morphologically and biologically diverse group of vascular channel abnormalities that are often congenital but may evolve or change over time in the developing child. Classification is based on a combination of physical and biological properties and clinical behavior that differentiate primarily between tumors and malformations and includes a few provisionally unclassified lesions. Anomalies of the gastrointestinal (GI) tract may present clinically with GI bleeding, abdominal pain, high-output cardiac failure, and malabsorption. Read More

Congenital Hemidysplasia with Ichthyosiform nevus and Limb Defects (CHILD syndrome) is a rare X-linked dominant genodermatosis caused by mutations in the NAD(P) dependent steroid dehydrogenase-like protein gene. Its defect leads to accumulation of toxic metabolic intermediates upstream from the pathway block and to the deficiency of bulk cholesterol, probably leading to altered keratinocyte membrane function, resulting in the phenotype seen in CHILD syndrome. Symptomatic treatment using emollients and retinoids to reduce scaling has long been used until recently, whereby new therapeutic means based on the pathogenesis-targeted therapy have been developed.
