Abstract

Polymorphous Low-Grade Adenocarcinoma (PLGA) is a neoplasm that frequently occurs in the minor salivary glands located in the mucosa of the soft and hard palates, the buccal mucosa, and the upper lip. It rarely occurs in the nasopharynx, and only six such cases have been reported. Nasopharyngeal PLGA can be treated by wide local excision with no additional treatment. We report a case of PLGA originating in the nasopharynx mucosa. We were able to completely resect the tumor using simple endoscopic surgery rather than an open approach, such as a transpalatal resection. Our patient had no local recurrence or distant metastasis at 24-months follow-up.
