Basal cell adenoma in a relatively rare site

Abstract

Basal cell adenoma (BCA) of the salivary glands is an uncommon type of monomorphic adenoma. Its most frequent location is the parotid gland. It usually appears as a firm and mobile slow-growing mass. Histologically, it is seen as nests of isomorphic cells and interlaced trabeculae with a prominent basal membrane. There is also slack, hyaline stroma with absence of a myxoid or chondroid component. We describe a case of BCA of palatal minor salivary glands, a rare site for its occurrence. We also briefly review the literature on the same.
