Two Cases of Acinic Cell Tumor

Abstract

Two cases of acinic cell tumors, originating in the parotid gland and in the minor salivery gland, were reported.
A 71-year-old, complained of a swelling in his right parotid area which he had first noticed one year earlier. The tumor located in his right parotid gland was detected and extracted with surrounding normal tissues by operation. The patient had no trouble 47 months after operation.
The o ther patient was an 88-year-old male who noticed a swelling at the surface of oral mucosa. The tumor located on the soft palate was removed by laser technique.
Pathological study revealed the tumors in both cases to be acinic cell tumor. Eighteen months after the first operation, the tumor had recurrend locally, and, radical operation was performed. This operation caused pneumonia because of swallowing disturbance due to advanced age. The patient died 3 months from the secound operation. No local recurrence and no metastasis to other organs was suggested by autopsy.
We reviewed the reports of acinic cell tumor in Japan.
