Acinic cell carcinoma (ACC) is a rare, low-grade malignancy of the salivary glands. Most cases occur in the major salivary glands, especially the parotid gland, with only a few cases involving the minor salivary gland previously described. A 67-year-old male patient was admitted complaining of an obstructive feeling in the throat. On examination, a lobulated mass in the tonsillar surface was noticed. Tonsillectomy was performed under general anesthesia. Histopathological examination of the mass revealed sheets of large, polygonal acinar cells with granular, slightly basophilic cytoplasm, which led to the diagnosis of ACC. Here, we present a case of low-grade ACC of the palatine tonsil, which we believe to be the first reported case of ACC in this location.
