Synchronous double basal cell adenoma of the parotid gland: Report of a case

Abstract

Salivary gland tumors commonly occur as a single focus in one salivary gland. Warthin tumor often arises in bilateral parotid glands, and the membranous type of basal cell adenoma frequently occurs in unilateral parotid glands. We describe herein a case of extremely rare synchronous double solid type basal cell adenoma arising in the left parotid glands in a 49-year-old woman. This case was treated with surgical enucleation, and no signs of recurrence have been seen as of 4 years 3 months after surgery.
