Muir-Torre syndrome: a case of unusual coexisting genetic mutations.

Muir-Torre syndrome (MTS) is a rare autosomal dominant geno-dermatosis that was independently described by Muir in 1967 and Torre in 1968. MTS is a phenotypic subtype of Lynch syndrome and most commonly arises due to germline mutations in mismatch repair genes. MTS manifests with at least one cutaneous neoplasm and one visceral malignancy.
