This review provides a comprehensive overview of the dermatological signs associated with these syndromes, aiming to facilitate their recognition in clinical practice. Hereditary Breast and Ovarian Cancer syndrome is notably linked to an increased risk of melanoma. BAP1 tumor predisposition syndrome is characterized by BAP1-inactivated melanocytic tumors. Muir–Torre syndrome, a variant of Lynch syndrome, presents with distinctive cutaneous neoplasms such as sebaceous carcinomas, sebaceous adenomas, and keratoacanthomas. PTEN hamartoma tumor syndrome commonly features hamartomatous growths, trichilemmomas, acral keratoses, oral papillomas, and genital lentiginosis. Gorlin syndrome is marked by basal cell carcinomasand palmoplantar pits, while Peutz–Jeghers syndrome is identified by mucocutaneous pigmentation. In familial adenomatous polyposis, the cutaneous findings include epidermoid cysts, fibromas, desmoid tumors, and lipomas. Additionally, we examined monogenic disorders associated with cancer risk and skin involvement, such as xeroderma pigmentosum, neurofibromatosis type 1, familial atypical multiple-mole melanoma syndrome, and Fanconi anemia. The early recognition of these dermatologic features is essential for a timely diagnosis and the implementation of appropriate surveillance strategies in individuals with hereditary cancer syndromes.  \nKeywords: hereditary cancer; skin; early diagnosis; dermatological manifestations; genodermatosis  \n1. Introduction  \nHereditary cancer predisposition syndromes account for approximately 10% of all cancer etiologies [1] . These syndromes are variable and present with distinctive tumorsand/or clinical features that help us to suspect and determine the diagnosis [2] . In some cases, cutaneous manifestations could be the first sign that we observe, for example, mucocutaneous pigmentations seen in Peutz–Jeghers syndrome [3]; palmar pits in Gorlin syndrome [4]; nonmalignant neoplasms, presenting as sebaceous adenomas or epitheliomas, seen in Muir–Torre syndrome [5]; or even malignant neoplasms such as basocellular carcinoma (BCC), squamous cell carcinoma (SCC), and cutaneous melanoma.  \nThis review aims to provide a comprehensive overview of all the dermatologic manifestations observed in both here","cbCaioW2mUzaV4eg","https://ap.wps.com/l/cbCaioW2mUzaV4eg","pdf",2584344,"English","# Abstract\n# 1.
