    Be vigilant for skin manifestations of inherited cancer syndromes.
    Practitioner 2017 01;261(1800):23-7
    More than 200 hereditary cancer susceptibility syndromes have been described, and it is thought that they account for 5-10% of all cancers. Many have dermatological manifestations (usually lesions, occasionally rashes) which frequently precede other systemic pathology. Dermatological signs are usually non-specific and often trivial in appearance, making their significance easy to overlook and a clinical diagnosis challenging. Read More

    Improvement of Genetic Testing for Cutaneous Melanoma in Countries With Low to Moderate Incidence: The Rule of 2 vs the Rule of 3.
    JAMA Dermatol 2017 Nov;153(11):1122-1129
    Service de Dermatologie Centre Hospitalier, Lyon Sud, France.
    Importance: Genetic testing for melanoma-prone mutation in France, a country with low to moderate incidence of melanoma, is proposed in cases with 2 invasive cutaneous melanomas and/or related cancers in the same patient, or in first- or second-degree relatives (rule of 2). In preclinical studies, these rules led to disclosure of mutation(s) in more than 10% of these families, the threshold widely accepted to justify genetic testing for cancers.

    Objective: To reconsider these criteria in a general population testing of patients. Read More

    [Recognition and follow-up of the atypical naevus: benign marker or precursor of melanoma?]
    Ned Tijdschr Geneeskd 2016 ;160(0):D216
    LUMC, afd. Dermatologie, Leiden.
    Dysplastic (atypical) naevi have long been subject to discussion with regard to their nature; even their existence has been doubted. Recently, the atypical naevus has been formally identified by molecular genetic characteristics as an intermediate lesion between banal naevi and melanoma. However, the atypical naevus, as long as it is stable and asymptomatic, is regarded as a benign lesion that does not warrant excision. Read More

    Genomic Characterization of Dysplastic Nevi Unveils Implications for Diagnosis of Melanoma.
    J Invest Dermatol 2017 Apr 24;137(4):905-909. Epub 2016 Nov 24.
    Department of Dermatology, Icahn School of Medicine at Mount Sinai, New York, New York, USA; Department of Pathology, Icahn School of Medicine at Mount Sinai, New York, New York, USA. Electronic address:
    A well-defined risk factor and precursor for cutaneous melanoma is the dysplastic nevus. These benign tumors represent clonal hyperproliferation of melanocytes that are in a senescent-like state, but with occasional malignant transformation events. To portray the mutational repertoire of dysplastic nevi in patients with the dysplastic nevus syndrome and to determine the discriminatory profiles of melanocytic nevi (including dysplastic nevi) from melanoma, we sequenced exomes of melanocytic nevi including dysplastic nevi (n = 19), followed by a targeted gene panel (785 genes) characterization of melanocytic nevi (n = 46) and primary melanomas (n = 42).

    J Am Acad Dermatol 2017 Feb 9;76(2):244-249. Epub 2016 Nov 9.
    Department of Dermatology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania. Electronic address:
    Background: Dysplastic nevi with severe atypia (severely dysplastic nevi [SDN]) are frequently re-excised because of the concern that these lesions may in fact represent early melanoma. Data on long-term follow-up of these patients are limited.

    Objective: We sought to determine the rate of subsequent melanoma development in patients with SDN who underwent re-excision versus those who did not and to determine factors associated with decision to re-excise. Read More

    Reexcision Perineural Invasion and Epithelial Sheath Neuroma Possibly on a Spectrum of Postinjury Reactive Hyperplasia Mediated by IL-6.
    Am J Dermatopathol 2017 Jan;39(1):49-52
    *Department of Pathology and Laboratory Medicine, Weill Cornell Medicine, New York, NY; †Ohio State University Comprehensive Cancer Center, Columbus, OH; and ‡NYC Dermatology and Cosmetic Center, New York, NY.
    Epithelial sheath neuroma is a rarely recognized but established entity in the medical literature. First described in 2000 by Requena et al, there have only been 7 published cases to date, mostly in female patients and presenting as symptomatic solitary lesions on the back without a known history of trauma. In 2006, Beer et al described and reviewed a dozen cases in which epithelial sheath neuroma-like features were seen in the advent of a surgical procedure, which was termed "re-excision perineural invasion" and attributed to possible eccrine duct implantation during surgery.

    Department of Dermatology and Venereology, University Hospital Centre (CHUV) and University of Lausanne (UNIL), Lausanne, Switzerland. Electronic address:
    Differentiation of proliferative nodules in giant congenital nevi from melanoma arising within such nevi is an important diagnostic challenge. DNA methylation is a well-established epigenetic modification already observed in the earliest stages of carcinogenesis, which increases during melanoma progression. The ten-eleven translocation enzymes catalyze the oxidation of 5-methylcytosine to 5-hydroxymethylcytosine (5-hmC), which has recently been reported as an epigenetic hallmark associated with tumor aggressiveness and poor prognosis in a wide variety of cancers.
