The lipoma is a rare intraoral tumor, although it occurs almost anywhere on the body. We reported clinico-pathological examination in 15 cases of lipoma and 2 cases of lipoma like lesion (herniation of buccal fat pad) during the past 28 years and 7 months from January 1961 to July 1989. 15 cases of lipoma were separated 10 cases of superficial type from 5 cases of diffuse type. 15 cases of lipoma were clinico-pathologicaly similar to those described in the past reports. Results obtained were as follows: 1) The lipoma patient age ranged from 19 to 70 years and the average age was 53. 1 years. On the other hand the age of herniation of buccal fat pad patient was infant in 2 cases. 2) In lipoma, 8 cases were male and 7 cases were female. Both herniation of buccal fat pad cases were female. 3) Lipoma in 6 cases appeared in the buccal mucosa, 3 in the tongue, 3 in the lip, in the oral floor, and in the mucogingival junction. 4) The duration of symptoms in lipoma ranged from 5 days to 16 years, but on the other hand the duration of symptoms in herniation of buccal fat pad ranged from 3 days to 2 days. 5) The average size of lipoma and herniation of buccal fat pad was both about 20 mm in diameter. 6) Superficial type of lipoma which was yellowish, and pedunclated with a clear border was more easily diagnosed than diffuse type of lipoma which was normal mucosa color and had a vague border. 7) 12 tumors were histologically diagnosed as lipoma, 3 as fibrolipoma.
