抄録

The authors reported a case of "fibroma durum", which grew on the hard palate.The patient was a 38-year-old male labourer, and he noticed a small node in the front part of the hard palate five years ago.Thetumor enlarged gradually but no subjective symptoms were complained. When the tumor was removed it was found to be a mass about the size of the tip of a thumb, and attached to the median line of the hard palate with a short peduncle. From the histological point of view, the tumor was a typical fibroma durum.Among the benign tumors which rise in the oral cavity, the tumor of the hard palate origin is uncommon. Especially fibroma is rare. Besides, a statistical observation was performed on 53 cases of oral tumors out of 58865 patients who had visited our clinic for the last 5 years.
