title: Spiradenomas.
abstract: We report a 52-year-old man with a one-year history of multiple, firm, skin-colored nodules on the vertex of the scalp. Histopathologic examination was consistent with a spiradenoma, which is a rare, benign adnexal tumor of controversial histogenesis. Multiple spiradenomas may arise in association with Brooke-Spiegler syndrome, which is an autosomal dominant condition of multiple cyclindromas, trichoeptheliomas, and cyclindromas.
