Syndromes néoplasiques héréditaires avec atteinte cutanée [Cutaneous lesions in genetic tumor syndromes]

Genetic tumor syndromes reflect an inherited predisposition to develop benign and malignant tumors. Increased frequency of neoplasms within the family or occurring at an early age are clinical clues for a possible underlying genetic susceptibility. Awareness of their associated cutaneous manifestations can facilitate early detection of risk for tumors. The goal of this article is to review clinical and molecular features of some genetic tumor syndrome which present with skin involvement at birth or during childhood.
