A case of acinic cell carcinoma arising in the buccal mucosa: A review of the literature on acinic cell carcinoma of the minor salivary gland in Japan

Abstract

Acinic cell carcinoma derived from minor salivary glands is an extremely rare malignancy of the salivary glands. We report a case of a 69-year-old female who developed acinic cell carcinoma derived from the minor salivary glands. The patient visited our department with the chief complaint of the sensation of a mass in the right buccal mucosa. MRI showed a 25×20mm mass, and the tumor was excised under general anesthesia. Histopathological examination showed proliferation of cancer cells close to the minor salivary glands, and serous acinar cells accounted for a majority of the cancer cells. No evidence of any recurrence or metastasis was observed during the 20-month follow-up period.
