Abstract

Brooke-Spiegler syndrome (BSS), familial cylindromatosis (FC), and multiple familial trichoepithelioma (MFT), originally described as distinct entities, share overlapping clinical findings. Patients with BSS are predisposed to multiple skin appendage tumors such as cylindroma, trichoepithelioma, and spiradenoma. FC, however, is characterized by cylindromas and MFT by trichoepitheliomas as the only tumor type. These disorders have recently been associated with mutations in the CYLD gene. In this report, we describe three families with BSS, one with FC, and two with MFT phenotypes associated with novel and recurrent mutations in CYLD. We provide evidence that these disorders represent phenotypic variation of a single entity and lack genotype-phenotype correlation.
