Familial cylindromatosis (OMIM: 132700), Brooke-Spiegler syndrome (BRSS) (OMIM: 605041), and multiple familial trichoepithelioma 1 (MFT1) (OMIM: 601606) were originally described as distinct clinical entities. Patients with BRSS develop multiple skin appendage neoplasms including cylindromas, trichoepitheliomas, and spiradenomas. Patients with familial cylindromatosis have only cylindromas, and those with MFT1 have only trichoepitheliomas. However, because these disorders show overlapping phenotypic features, and because different manifestations of each have been described within a single family, many consider these disorders to represent a phenotypic spectrum of a single disease entity. All are caused by mutations in the CYLD gene.
