[Brooke-Spiegler syndrome: an heterogeneous entity].

The Brooke-Spiegler syndrome is a rare, autosomally dominant disease with a predisposition to develop different adnexal tumors. Clinically it is characterized by the presence of multiple cylindromas, trichoepitheliomas, and occasionally, spiradenomas. Although Brooke-Spiegler syndrome, familial cylindromatosis and multiple familial trichoepithelioma were initially described as separate entities, the recently identified identical mutations in the gene of cylindromatosis suggest that they represent fenotypic variations of the same entity. In this article we present the case of a woman and her daughter, both affected by this rare genodermatosis.
