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.
