- basal cell adenoma
- a benign, encapsulated, slow-growing, painless salivary gland tumor of intercalated duct or reserve cell origin, usually seen in males in the parotid gland or upper lip. Solid, canalicular, trabecular-tubular, and membranous types have been distinguished histologically, but all show little myoepithelial cell participation, stromal differentiation, or metaplasia.
