Giant basal cell adenoma of the parotid gland eroding the ramus of mandible: An unusual presentation

Abstract

Basal cell adenoma (BCA) is an uncommon benign salivary gland epithelial tumor. BCA accounts for 1-2% of all salivary gland epithelial tumors and more than 80% of BCA′s arise in the major salivary glands, mostly the parotid. It is usually firm in consistency, mobile, slow growing mass, and tends to be multiple. Due to the prognostic implications, differential diagnosis with basal cell adenocarcinoma, adenoid cystic carcinoma, and basaloid squamous cell carcinoma is essential. We present a giant BCA of the left parotid gland eroding the ramus of mandible in an elderly female and discuss its diagnostic work-up and surgical management.
