Cancer occuring in the dorsum of the tongue is very rare. Several reports indicate that the rate of cancer occurrence in the dorsal tongue ranges from 2.8% to 7.2 % of all tongue cancer.<BR>In our clinic, there has been only one case of dorsal tongue cancer among 89 cases of tongue cancer from 1979 to 1992.<BR>The patient was a 68-year-old male who visited our clinic with a chief complaint of a tumor mass in the left dorsum of the tongue in November 1983.<BR>The tumor was a round, circumscribed, raised, and centrally depressed mass with a red surface. It was 15 mm in diameter and elastic but firm in consistency.<BR>Macroscopically, the tumor was doughnut-shaped.<BR>Pathologically, the tumor was diagnosed to be a squamous cell carcinoma.<BR>He was treated by intraoral electron therapy, one time (10 Gy) per week. The total dose amounted to 40 Gy. Clinically and pathologically, the tumor disappeared at that time.<BR>Nine years after intraoral electron therapy, he is still alive without primary recurrence or distant metastasis.
