Abstract

Muir-Torre syndrome (MST) is a rare autosomal dominant subtype of
hereditary non-polyposis colorectal carcinoma. The diagnosis is established based
on the coexistence of sebaceous gland tumors and visceral organ malignancies.
Mutations in the mismatch repair genes are responsible for Muir-Torre syndrome.
Internal malignancies seen in MTS are most commonly colorectal, gastrointestinal
system, endometrial, genitourinary system, breast, lung, brain, and hepatobiliary
system malignancies. Detection of sebaceous neoplasia is essential in investigating
Muir-Torre syndrome, allowing early detection of internal malignancies. Herein, we
present the case of a patient with sebaceous adenomas, internal malignancies, and
a new mutation detected during the genetic examination.
