Pleomorphic adenoma in the maxillary sinus is extremely rare.
A 33-year-old female had been complaining of purulent nasal discharge. Radiographically, the left maxillary antrum was opaque, showing water density and a soft mass density. The patient was operated on, and a tumor with a cyst was resected. The diagnosis of the tumor was pleomorphi c adenoma. The patient showed no evidence of recurrence of the tumor for 28 months postoperativelly.
The clinical importance and general knowledge of pleomorphic adenoma are reviewed and discussed. In Japan, there have been only two other case reports of pleomorphic adenoma definitely diagnosed in the maxillary sinus.
