Abstract

Basal Cell Adenocarcinoma (BCAC) is a rare subtype of carcinoma of salivary glands. It accounts for 1.6% of all salivary gland neoplasms and 2.9% of malignant salivary gland neoplasms. BCAC is especially rare in parotid glands. The biological behavior of BCAC is invasive and destructive, with perineural and vascular invasion. This paper presents a BCAC with multiple recurrences and wide local extension in a 71-year-old Iranian woman with a 30-year history of a large mass on the right side of her neck. The importance aspects of this case were its long duration, multiple recurrences, facial nerve involvement and the use of clinicopathological criteria for diagnosis.
