Acinic cell carcinoma in minor salivary glands of retromolar trigone

Abstract

Acinic cell carcinoma (ACC) is a rare malignant tumor of the salivary glands. ACC of the minor salivary glands is very rare. In the oral cavity, minor salivary gland tumors are rarely seen in the inferior anatomic regions like the retromolar trigone and the floor of mouth compared to the superior regions like the palate. We present a retromolar trigone ACC, a rare location in the oral cavity and discuss the relevant reports in the literature.
