title: Endomandibular acinic cell carcinoma.
abstract: A rare case of endomandibular acinic cell carcinoma (ACC) in a white woman aged 79 is reported. Radiologic examination revealed an osteolytic area within the jaw, extending from the left molar region to the ascending branch. The tumor was located within a cavity of the mandible and did not seem to infiltrate the bone. Histologically, it was composed of large epithelial cells with granular cytoplasm, arranged in solid nests, sometimes displaying microcystic spaces. ACC generally occurs in salivary glands. In the reported case, the tumor was considered to arise from ectopic salivary tissue enclosed in the jaw, as no lesion was found in minor salivary glands.
