Basal Cell Adenoma in the Parotid Gland: A Case Report of Rare Salivary Gland Tumor

Abstract

Salivary gland tumors are rare and constitute about 2 to 6.5% of all head and neck neoplasms. Basal cell adenoma (BCA) is a rare benign tumor in salivary gland, accounting for 1 to 3% of all salivary gland tumors. Histopathologically, BCA is composed of basaloid cells and can be classified into solid with most common type, trabecular, tubular, and membranous types. It is mainly found in the parotid gland, and it is commonly treated via a parotidectomy. In this study, we report a case of surgical excision trabecular-tubular mixed type BCA in the surface of the parotid gland, with preservation of the facial nerve and body of the parotid gland.
