Salivary basal cell adenoma

What it means

A rare neoplasm consisting of a monomorphic population of basaloid epithelial cells, and it accounts for approximately 1-2% of all salivary gland tumors.

Thee most frequent location of basal cell adenoma (BCA) of the salivary gland is the parotid gland. It usually appears as a firm and mobile slow-growing mass. Histologically, isomorphic cells in nests and interlaced trabecules with a prominent basal membrane are observed. In contrast to pleomorphic adenoma, it tends to be multiple and its recurrence rate after surgical excision is high.
