Tumorous proliferations are often observed in the oral cavity. These are commonly found in adults. Although the lesions may be seen throughout the mouth, they frequently occur on gingiva, buccal mucosa, tongue, and lower lip.
This report is concerned with two cases of inflammatory fibrous hyperplasia in the area of the buccal mucosa. The findings were as follows:
1. Two cases were found in an 11 year,4 month-old Japanese female and 8 year,6 month-old Japanese male.
2. Intraoral examination revealed a smooth, normal colored, and well-defined mass with pedicles in two cases. Clinical diagnosis of each case revealed suspicion of mucocele.
3. Histopathologically, the lesion of each case consisted of an excessive bulk of collagen fibers interspersed with some small blood vessels, nuerofibril bulks, and a small number of inflammatory cells infiltration. There was no salivary gland. The histopathological diagnosis was inflammatory fibrous hyperplasia in two cases.
4. The treatment was simple excision of the inflammatory fibrous hyperplasia and the lesion has not recured in each case.
