title: [Acinic cell tumor of the epipharynx--a patient treated with surgery and high-dose intracavitary radiation therapy].
abstract: A case of acinic cell tumor of the epipharynx is reported. The patient was a 41-year-old man. The tumor was surgically removed by the transpalatal approach. Light microscopically, the lesion was composed of serous acinic cells with eosinophilic granules, clear cells with water-clear cytoplasm and their intermediate type, vacuolated cells. The serous acinic cells were PAS (periodic acid-Schiff)- and DPAS (PAS with diastase predigestion)-positive. The clear and vacuolated cells were PAS- and DPAS-negative. The patient underwent early postoperative radiation therapy; high-dose intracavitary radiation therapy using remote-controlled afterloading equipment was given subsequent to the external radiation therapy. The patient has been free of recurrence and abnormal findings for one year after treatment.
