The Muir-Torre Syndrome is a rare genodermatosis, defined by the occurrence of cutaneous tumors (such as sebaceous adenomas, epitheliomas, or carcinomas, and/or keratoacanthomas), and internal malignancies. Recently, molecular analysis in hereditary non polyposis colorectal cancer demonstrated a common genetic basis, linking these two disorders, with the observation of germline mutations in the hMSH2 gene (one of the DNA mismatch repair system genes) in both syndromes. Such molecular demonstration of a single nosological entity should be clinically used to improve the indications of molecular testings in oncogenetics, still restricted to highly stringent criteria for hereditary non polyposis colorectal cancer.
