Abstract

Multiple dermal cylindromas and membranous basal cell adenoma of parotid gland in a 67-year-old woman with Brooke-Spiegler syndrome (BSS) were examined by fine-needle cytology. Histology, immunochemistry, and CYLD germline mutation testing were also performed. Cytomorphology and immunochemistry of the two lesions showed basaloid neoplasms, remarkably similar, composed by proliferating epithelial cells of basal type accompanied by a smaller proportion of myoepithelial cells. CYLD gene showed a novel germline splice acceptor site mutation (c.2042-1G>C) with skipping of the entire exon 15. The occurrence of analogous tumors, dermal cylindromas, and membranous basal cell adenoma of the parotid gland, in the same patient may result from the action of a single gene on ontogenetically similar stem cells. Therefore, patients with BSS should be offered a genetic counselling for an early and correct diagnosis. Diagn. Cytopathol. 2015;43:654-658.
