Abstract
Acinic cell carcinoma is a rare and low-grade malignant tumor of the parotid gland. We treated two acinic cell carcinomas of the parotid gland, each occurring in a young man (18 and 30 years old, respectively). Based on preoperative examination and MRI findings, we expected to find benign tumors, but they were revealed to be acinic cell carcinomas by the permanent pathological specimens. We performed partial parotidectomy in one case, and subtotal parotidectomy in the other, and preserved the facial nerve in both. There has been no metastasis or recurrence for two years after the operations, but we need to follow both patients for a long time.
