Abstract
Cystadenocarcinoma is an uncommon salivary gland tumor that occurs in the palate. We report a rare case of cystadenocarcinoma arising in the palate. A 80-year-old man visited a certain hospital because of a painless swelling in the palate. A biopsy was performed, and adenocarcinoma was diagnosed histopathologically. He was therefore referred to our hospital to receive treatment for adenocarcinoma. He had a painless swelling, measuring 25 × 15 mm, in the left side of the palate. Computed tomography showed no evidence of cervical metastasis. Partial maxillectomy was performed, and the final histopathological diagnosis was cystadenocarcinoma. There was no evidence of recurrence or metastasis 20 months after the operation.
