A Rare Case of Basal Cell Adenoma in the Bilateral Parapharyngeal Space

Abstract

A rare case of basal cell adenoma in the bilateral parapharyngeal space is reported. A tumor in the left parapharyngeal space was bluntly enucleated by the cervical-parotid approach and two tumors in the right side were enucleated by the cervical approach. Pathological diagnosis of all three tumors was identical to basal cell adenoma. Multiple occurrence of this benign tumor in the bilateral parapharyngeal space required a careful follow-up because the differential diagnosis of basal cell adenoma between basal cell adenocarcinoma and adenoid cystic carcinoma is usually highly confusing.
