Detection of a multi-lineage mosaic NRAS mutation c.181C>A (p.Gln61Lys) in an individual with a complex congenital nevus syndrome.

Pigment Cell Melanoma Res 2018 Dec 7. Epub 2018 Dec 7.

Institute of Human Genetics, University Hospital Otto-von-Guericke-University, Magdeburg, German.

Mosaic RASopathies constitute a clinically and genetically heterogeneous group of non-inherited congenital (neuro)cutaneous disorders caused by postzygotic mutations in genes encoding components of the RAS-MAPK signaling pathway (Luo & Tsao, 2014). There are striking genotype-phenotype correlations within this group but also clinical features overlapping between distinct disorders. Congenital melanocytic nevi (CMN) are the most common lesions falling into the category of mosaic RASopathies. Read More

Proliferating Neurocristic Hamartoma Arising in a Giant Congenital Nevus: Comparative Genomic Hybridization Findings.

Am J Dermatopathol 2018 Nov 15. Epub 2018 Nov 15.

Deramatology, Hospital Universitario 12 de Octubre, Universidad Complutense, Instituto de Investigación I+12, Madrid, Spain.

Neurocristic cutaneous hamartomas (NCHs) are rarely reported tumors with divergent differentiation derived from persistently active pluripotent cells from the neural crest. They result from aberrant development of the neuromesenchyme, and they can express fibrogenic, melanocytic, and/or neurosustentacular differentiation. Thus, congenital melanocytic nevus also represents a neurocristic dysplasia of the skin in which cells are melanogenic cells arrested in development located in the reticular dermis, and nodular proliferative neurocristic hamartoma may arise within a congenital melanocytic nevus.

Novel KHDRBS1-NTRK3 rearrangement in a congenital pediatric CD34-positive skin tumor: a case report.

Virchows Arch 2018 Sep 6. Epub 2018 Sep 6.

Department of Dermatology, Unit of Pediatric Dermatology - CHRU Tours, Tours, France.

Cutaneous spindle-cell neoplasms in adults as well as children represent a frequent dilemma for pathologists. Along this neoplasm spectrum, the differential diagnosis with CD34-positive proliferations can be challenging, particularly concerning neoplasms of fibrohistiocytic and fibroblastic lineages. In children, cutaneous and superficial soft-tissue neoplasms with CD34-positive spindle cells are associated with benign to intermediate malignancy potential and include lipofibromatosis, plaque-like CD34-positive dermal fibroma, fibroblastic connective tissue nevus, and congenital dermatofibrosarcoma protuberans.

An update on molecular alterations in melanocytic tumors with emphasis on Spitzoid lesions.

Ann Transl Med 2018 Jun;6(12):249

First Department of Pathology, National and Kapodistrian University of Athens, Medical School, Athens, Greece.

Significant progress in the molecular pathology of melanocytic tumors have revealed that benign neoplasms, so-called nevi, are initiated by gain-of-function mutations in one of several primary oncogenes, such as in acquired melanocytic nevi, in congenital nevi or / in blue nevi, with consequent MAPK and PI3K/AKT/mTOR activation. Secondary genetic alterations overcome tumor suppressive mechanisms and allow the progression to intermediate lesions characterized by TERT-p mutation or to invasive melanomas displaying disruption of tumor suppressor genes. Currently, melanoma is molecularly regarded as four different diseases, namely , , and the "triple wild type" subtypes, which are associated with particular clinicopathological features. Read More

Phakomatosis pigmentovascularis (PPV) is an uncommon dermatosis characterised by the presence of both pigmentary and vascular abnormalities. Its pathogenesis is not elucidated, and the prognosis is mainly determined by the presence of extracutaneous manifestations, such as Klippel-Trenaunay syndrome (KTS), that is defined by the triad of a port-wine stain (PWS), anomalous veins and progressive overgrowth of the affected extremity. Herein, we report a case of an adult patient, who presented with a large PWS, nevus of Ota, ocular melanosis, and limb hypertrophy and varicosities. Read More

Inflammatory linear verrucous epidermal nevus associated with erosive monoarthritis.

Pediatr Dermatol 2018 Sep 4;35(5):e291-e293. Epub 2018 Jul 4.

Department of Dermatology, Hospital del Mar, Barcelona, Spain.

Inflammatory linear verrucous epidermal nevus and linear psoriasis are different entities with clinical and histopathologic similarities. Isolated reports of inflammatory linear verrucous epidermal nevus with concomitant psoriasis or a positive family history of psoriasis have been described, and the possibility that inflammatory linear verrucous epidermal nevus may be a mosaic form of cutaneous psoriasis has been postulated. We report a 17-year-old boy with a congenital, linear, erythematous, keratotic plaque on the dorsum of the fifth finger of the left hand with ipsilateral nail dystrophy. Read More

Molluscum contagiosum arising in a melanocytic congenital nevus.

Pediatr Dermatol 2018 Sep 4;35(5):e310-e311. Epub 2018 Jul 4.

Section of Dermatology, Department of Medical Science and Public Health, University of Cagliari, Cagliari, Italy.

Molluscum contagiosum within a congenital melanocytic nevus has rarely been reported. We report a 6-year-old child with molluscum contagiosum infection arising within an intermediate melanocytic congenital nevus of the thigh, associated with itching and occasional bleeding. Dermoscopy lead to the correct diagnosis, but histologic confirmation with shave biopsy was performed to reassure the parents and allow mechanical removal of the lesions using curettage. Read More

Congenital nevus comedonicus complicated by a hidradenitis suppurativa-like lesion: Report of a childhood case.

Pediatr Dermatol 2018 Sep 27;35(5):e298-e299. Epub 2018 Jun 27.

Division of Dermatology, Department of Experimental, Diagnostic and Specialty Medicine, Sant'Orsola-Malpighi Hospital, University of Bologna, Bologna, Italy.

Nevus comedonicus is a rare, benign hamartoma of the pilosebaceous unit that may be isolated or part of the nevus comedonicus syndrome. Although rare in children, complication by hidradenitis suppurativa-like lesions has been described. We present a report of a 9-year-old girl in whom surgical excision was curative, with a review of the relevant literature. Read More

Neurocutaneous melanosis presenting with hydrocephalus and malignant transformation: case-based update.

Childs Nerv Syst 2018 Aug 12;34(8):1471-1477. Epub 2018 Jun 12.

University Hospital of Wales, Cardiff, UK.

Introduction: Neurocutaneous melanosis (NCM) is a sporadic condition characterised by congenital melanocytic nevi and melanocytic thickening of the leptomeninges. It is believed to result from congenital dysplasia of melanin-producing cells within the skin and leptomeninges. The management of cutaneous manifestations remains controversial; for neurological manifestations, outcome remains poor even with the use of radiotherapy and chemotherapy. Read More

Giant congenital melanocytic nevus in a Cameroonian child: a case report.

J Med Case Rep 2018 Jun 23;12(1):175. Epub 2018 Jun 23.

Department of Internal Medicine and Sub-specialties, Faculty of Medicine and Biomedical Sciences, University of Yaoundé I, Yaoundé, Cameroon.

Background: Giant congenital melanocytic nevus is a very rare condition characterized by a large skin lesion and an increased risk of complications like neurocutaneous melanosis and malignant transformation. Reports of giant congenital melanocytic nevus are scarce in the sub-Saharan African literature and here we present a case of this disease in a Cameroonian adolescent.

Case Presentation: A 12-year-old Cameroonian girl from the "Baka" ethnic group, with no relevant family and medical histories presented with a progressively extensive brownish-black nodular hypertrophic skin lesion of approximately 45 cm, which she had had since she was 2-days old. Read More

Proportionate growth of congenital nevi: Blow a balloon to explain.

Pediatr Dermatol 2018 Sep 22;35(5):690-692. Epub 2018 Jun 22.

Department of Dermatology, Venereology, and Leprosy, Sri B.M. Patil Medical College, Hospital& Research Center, BLDE University, Vijayapur, Karnataka, India.

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.

Klippel-Trenaunay and Parkes-Weber syndromes: two case reports.

J Vasc Bras 2017 Oct-Dec;16(4):320-324

Universidade de São Paulo - USP, School of Medicine, Unit of Interventional Radiology, São Paulo, SP, Brazil.

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

Pulmonary thromboembolic events in patients with congenital lipomatous overgrowth, vascular malformations, epidermal nevi, and spinal/skeletal abnormalities and Klippel-Trénaunay syndrome.

J Vasc Surg Venous Lymphat Disord 2018 07;6(4):511-516

Division of Vascular and Interventional Radiology, Vascular Anomalies Center, Boston Children's Hospital and Harvard Medical School, Boston, Mass. Electronic address:

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

Targeted therapy in patients with PIK3CA-related overgrowth syndrome.

Nature 2018 06 13;558(7711):540-546. Epub 2018 Jun 13.

INSERM U1151, Institut Necker Enfants Malades, Paris, France.

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.
