Abstract
We examined a case of a 69 year old male who developed an acinic cell tumor in his left maxillary sinus. He underwent partial maxillotomy on the left side and subsequent radiotherapy at another clinic. Although the tumor disappeared, he visited our clinic thereafter for a recurrence from the medial wall of the left maxillary sinus to the left nasal cavity. The medial wall was incised with a left lateral rhinotomy. About one year and two months later, a local recurrence was observed on the superior wall of the left maxillary sinus. The tumor was scraped along the superior wall of the left maxillary sinus. When we attempted to treat recurrence of the tumor with external application of 5-FU ointment, the tumor disappeared and no reccurence has been observed for the last 9 months. We report this case here and discuss the treatment method.
