PANTOJA, A et al. Sebaceous carcinoma associated with Muir-Torre syndrome: report of a case. Rev. argent. dermatol. [online]. 2016, vol.97, n.1, pp.43-53. ISSN 1851-300X.

The Sebaceous Carcinoma (SC) is an uncommon malignant tumor formed by cells that show differentiation toward sebaceous epithelium. It usually occurs in women of average at 70 years of age. We report a case of a 69 years old female with a family history of multiples cancer, breast cancer and the emergence of multiple sebaceous adenomas and carcinomas, features consistent with Syndrome Muir Torre (SMT). The 75% of the SC are located in the ocular region and the 25% rest presents extraocular location. The eye location is characterized by aggressive behavior, with direct extension and high potential for regional and distant metastases. Extraocular are generally less aggressive tumors and are located mainly in the head and neck. The pathogenesis is unclear, but chronic inflammatory processes, ultraviolet radiation and radiation will favor its development. The SC is a versatile tumor that presents with different clinical and histological different growth patterns, which retard the definitive diagnosis. SC is one of the cutaneous diagnostic markers of SMT, which is a genetic disease associated with visceral neoplasms. They are carefully assessed, performing a proper personal and family cancer history. The treatment of choice is the surgery with wide margins.
