    Knowledge of the molecular underpinnings of many epidermal nevi and epidermal nevus syndrome has expanded rapidly in recent years. In this review and update on epidermal nevus syndrome, we will cover recent genetic discoveries involving epidermal nevi, including nevus sebaceus, keratinocytic epidermal nevus, nevus comedonicus, congenital hemidysplasia with ichthyosiform nevus and limb defects syndrome, phakomatosis pigmentokeratotica, Becker's nevus, porokeratotic adnexal ostial nevus, inflammatory linear verrucous epidermal nevi, and cutaneous-skeletal hypophosphatemia syndrome. We will discuss how newly defined mutations relate to the biology reflected in the cutaneous patterns seen in these mosaic disorders and how new molecular data has informed our understanding of these diseases and shaped management decisions.

    Epidermal nevus syndromes.
    Handb Clin Neurol 2015 ;132:291-316
    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.

    Nevus sebaceus: a clinicopathological study of 168 cases and review of the literature.
    Int J Dermatol 2016 Feb 17;55(2):193-200. Epub 2015 Sep 17.
    Department of Dermatology, Razi Hospital, Tehran University of Medical Sciences, Tehran, Iran.
    Background: Nevus sebaceus is a hamartoma composed of abnormal epidermal and dermal components with clinical and histopathological features that change with aging. Prophylactic excision of the lesion was advised historically considering its potential for giving rise to malignant tumors. However, whether early prophylactic excision should be performed has been questioned recently as most of the tumors have been found to be benign in origin. Read More

    Secondary neoplasms arising from nevus sebaceus: A retrospective study of 450 cases in Taiwan.
    J Dermatol 2016 Feb 12;43(2):175-80. Epub 2015 Sep 12.
    Department of Dermatology, National Taiwan University Hospital and College of Medicine, Taipei, Taiwan.
    Nevus sebaceus is frequently associated with the development of secondary neoplasms.

    A Histological Snapshot of Hypothetical Multistep Progression From Nevus Sebaceus to Invasive Syringocystadenocarcinoma Papilliferum.
    Am J Dermatopathol 2016 Jan;38(1):56-62
    Departments of *Pathology, and †Dermatology, University of Alabama at Birmingham, Birmingham, AL.
    Syringocystadenocarcinoma papilliferum (SCACP) is an extremely rare adnexal neoplasm, believed to arise in a preexisting nevus sebaceus of Jadassohn (NSJ) through a multistep progression process. This hypothetical process involves an NSJ giving rise to syringocystadenoma papilliferum, which then presumably undergoes malignant transformation in rare circumstances to give rise to SCACP in situ, which finally progresses to an invasive SCACP. Of the 30 SCACP cases reported so far, none have documented the process from a birthmark to the final invasive lesion, with histological evidence of each step, in a single tumor. Read More

    Ceruminous adenoma (ceruminoma) arising in a nevus sebaceus of Jadassohn within the external auditory canal of a 3 year-old boy - A case report.

    Photoletter to the editor: A neurocutaneous rarity: phacomatosis pigmentokeratotica.
    J Dermatol Case Rep 2014 Jun 30;8(2):58-9. Epub 2014 Jun 30.
    Department of Dermatology, Freiburg University Medical Center, Freiburg, Germany.
    Phacomatosis pigmentokeratotica is characterized by the coexistence of nevus sebaceus, papular nevus spilus and associated neurologic abnormalities. We report a case of phacomatosis pigmentokeratotica in a 28-year-old male who presented with palmar-plantar dysesthesia and ipsilateral brain hemiatrophy. As a characteristic neuroimaging finding of the disorder, we found multiple hypointense lesions involving the ipsilateral hemisphere. Read More

    Update on pediatric dermatologic surgery from tots to teens.
    Curr Opin Pediatr 2014 Aug;26(4):452-9
    Department of Dermatology and Pediatrics, Oregon Health and Science University, Portland, Oregon, USA.
    Purpose Of Review: Children and their parents typically present to pediatricians to discuss treatment options for melanocytic nevi, nevus sebaceus, port-wine stains, and hemangiomas. Each of these conditions may be medically managed, but in some situations surgical intervention may be preferable.

    Recent Findings: Although recent studies have improved our understanding of melanoma risk among patients with congenital nevi, prospective trials are needed to more accurately assess whether surgical excision mitigates this risk. Read More
