It is estimated that 5% to 10% of the underlying mutations are hereditary and responsible for familial (or hereditary) melanoma. These patients are prone to the early development and higher risk of multiple melanomas. In recent years, an increasing number of genes have been identified thanks to genetic testing, allowing the subsequent surveillance of individuals at risk, yet it is still difficult to predict the presence of these mutations on a clinical basis. In this scenario, specific phenotypic and dermoscopic features could help clinicians in their identification. The aim of this work has been to correlate mutations to prevalent dermoscopic patterns, paving the way for reference models useful in clinical practice. In our cohort, out of 115 patients referred to genetic counseling for melanoma, 25 tested positive (21.7%) for critical mutations: CDKN2A (n = 12), MITF (n = 3), BAP1 (n = 1), MC1R (n = 3), PTEN (n = 1), TYR (n = 2), OCA2 (n = 1), and SLC45A2 (n = 2). The phenotype profiles obtained through the digital acquisition, analysis, and description of both benign and malignant pigmented lesions showed a predominance of the type II skin phenotype, with an elevated mean total nevus number (182 moles, range 75\u2013390). As for dermoscopic features, specific mutation-related patterns were described in terms of pigmentation, areas of regression, and vascular structures. Although further studies with larger cohorts are needed, our work represents the beginning of a new approach to the study and diagnosis of familial melanoma, underlining the importance of clinical and dermoscopic patterns, which may constitute a reference model for each gene, enabling comparison.<\/jats:p>","DOI":"10.3390\/cancers15153772","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T01:09:01Z","timestamp":1690333741000},"page":"3772","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Phenotypic and Dermoscopic Patterns of Familial Melanocytic Lesions: A Pilot Study in A Third-Level Center"],"prefix":"10.3390","volume":"15","author":[{"given":"Gabriele","family":"Roccuzzo","sequence":"first","affiliation":[{"name":"Department of Medical Sciences, Section of Dermatology, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Giordano","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Section of Dermatology, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Granato","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Section of Dermatology, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Cavallo","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Section of Dermatology, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Mastorino","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Section of Dermatology, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gianluca","family":"Avallone","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Section of Dermatology, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4373-1212","authenticated-orcid":false,"given":"Barbara","family":"Pasini","sequence":"additional","affiliation":[{"name":"Medical Genetics Unit, AOU \u2018Citt\u00e0 Della Salute e Della Scienza\u2019-\u2018Molinette\u2019 Hospital, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pietro","family":"Quaglino","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Section of Dermatology, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0098-1406","authenticated-orcid":false,"given":"Simone","family":"Ribero","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Section of Dermatology, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"291","DOI":"10.1615\/CritRevEukaryotGeneExpr.2020028454","article-title":"Malignant Melanoma: Skin Cancer-Diagnosis, Prevention, and Treatment","volume":"30","author":"Ahmed","year":"2020","journal-title":"Crit.
