A case of polymorphous low-grade adenocarcinoma in the soft palate

Abstract

Polymorphous low-grade adenocarcinoma (PLGA) is a rare malignant tumor arising from the minor salivary glands. We report a case of PLGA occurring in the soft palate. An 82-year-old man had been aware of a soft-palate mass for 7years. The mass was relatively large, measuring 50×60mm, and caused dysphagia and dysphonia. The lesion was clinically diagnosed as a tumor, and the patient underwent resection under general anesthesia. The mass was pathologically diagnosed as PLGA. The postoperative course was uneventful. There has been no recurrence or distant metastasis for 4years.
