    Transcatheter embolization of persistent embryonic veins in venous malformation syndromes.
    J Vasc Surg Venous Lymphat Disord 2017 Sep;5(5):749-755
    Division of Hematology and Oncology, Department of Pediatrics, Rutgers Robert Wood Johnson Medical School, New Brunswick, NJ; Cancer Institute of New Jersey at the Bristol-Myers Squibb Children's Hospital, Robert Wood Johnson University Hospital, New Brunswick, NJ.
    Persistent embryonic veins represent a major source of venous hypertension and morbidity in venous malformation syndromes, such as Klippel-Trénaunay syndrome and congenital lipomatous overgrowth, vascular malformations, epidermal nevus, and skeletal deformities syndrome. Surgical stripping and phlebectomy are the most commonly reported alternatives to compression therapy for refractory cases. These techniques, although effective in those patients who meet the necessary anatomic criteria, can be associated with bleeding, wound-related complications, and recurrence. Read More

    Department of Dermatology and Skin Diseases Research Center, University of Alabama at Birmingham, Birmingham, Alabama.
    Basal cell carcinoma (BCC) of the skin is driven by aberrant hedgehog signaling. Thus blocking this signaling pathway by small molecules such as vismodegib inhibits tumor growth. Primary cilium in the epidermal cells plays an integral role in the processing of hedgehog signaling-related proteins. Read More

    Phacomatosis Pigmentokeratotica: A Mosaic RASopathy with Malignant Potential.
    Pediatr Dermatol 2017 May;34(3):352-355
    Department of Dermatology and Dermatologic Surgery, Medical University of South Carolina, Charleston, South Carolina.
    Phacomatosis pigmentokeratotica (PPK) is a rare epidermal nevus syndrome characterized by the co-occurrence of a nevus sebaceous arranged along the lines of Blaschko with a speckled lentiginous nevus (SLN). We report a novel KRAS mutation in a patient with a large nevus sebaceous and an SLN who subsequently developed a vaginal botryoid rhabdomyosarcoma, an association not previously reported in the literature. This case expands our knowledge of the genetic basis for phacomatosis, in which mutations in HRAS have been previously described, although this report provides evidence that activating mutations in KRAS or HRAS may cause PPK.

    Several terms are widely used to define cutaneous lesions affecting the epidermis in association with extracutaneous lesions. Recently, based on the wide spectrum of cutaneous epidermal lesions, the various underlying molecular mechanisms and patterns of associated features have led to improved definitions of these disorders. Nevus sebaceous syndrome has been placed under the umbrella term of epidermal nevus syndrome, in which the nevus sebaceous, a congenital hamartomatous lesion of the epidermis, is associated with anomalies involving the brain, eyes, and bones.

    Neurocutaneous disorders are a heterogeneous group of conditions (mainly) affecting the skin [with pigmentary/vascular abnormalities and/or cutaneous tumours] and the central and peripheral nervous system [with congenital abnormalities and/or tumours]. In a number of such disorders, the skin abnormalities can assume a mosaic patterning (usually arranged in archetypical patterns). Alternating segments of affected and unaffected skin or segmentally arranged patterns of abnormal skin often mirror similar phenomena occurring in extra-cutaneous organs/tissues [eg, eye, bone, heart/vessels, lung, kidney and gut].

    Departments of Dermatology and Community and Family Medicine, University of California San Francisco, Santa Rosa, CA, USA. Electronic address:
    The term epidermal nevus syndrome (ENS) has been used to describe the association of epidermal hamartomas and extracutaneous abnormalities. Although many continue to use the term "ENS," it is now understood that this is not one disease, but rather a heterogeneous group with distinct genetic profiles defined by a common cutaneous phenotype: the presence of epidermal and adnexal hamartomas that are associated with other organ system involvement. One commonality is that epidermal nevi often follow the lines of Blaschko and it appears the more widespread the cutaneous manifestations, the greater the risk for extracutaneous manifestations.
