Abstract


Centrally occurring salivary gland tumors are rare. Because of a considerable overlap between the clinical and histopathological features, this group of tumors often produces a diagnostic difficulty to the clinicians and oral pathologists. Acinic cell carcinoma (ACC) is an unusual, low-grade, malignant salivary gland tumor that represents approximately 2% of the salivary gland tumors with almost 90% arising in the parotid gland. The rest involve the submandibular and the minor salivary gland. ACC of the jaw is extremely rare and, to our knowledge, only 8 cases have been reported in the English literature. Herein, a case of primary intraosseous ACC of the mandible in a 31-year-old woman is presented. The present case is unique, as the central ACC has never been reported in a patient in the third decade of life. The complete surgical removal of the tumor was carried out under general anesthesia along with the extraction of teeth #31, #32, #41, and #42. The follow-up period of 1-year was uneventful.
