抄録

Fibro-osseous lesions usually occur in bone and rarely arise from soft tissue in the head and neck region.This report describes a rare case of a fibro-osseous lesion occurring in the buccinator muscle. A 12-yearold boy visited Ehime University Hospital because of a painless swelling in the right buccal mucosa. An elastichard, well-defined mass was observed under the right buccal mucosa.On a panoramic X-ray film and a computed tomography scan, an oval radiopaque tumor, measuring 3×2cm, was observed in the region.A biopsy specimen revealed a fibro-osseous lesion with no evidence of malignancy.We extirpated the tumor with the patient under general anesthesia. The tumor was located in the buccinator muscle.Histopathological examination of the surgical specimen revealed ossifying fasciitis with small foci of metaplastic bone and fibrous tissue.The lesion was not contiguous with the mandible.The patient had no discomfort postoperatively and no evidence of recurrence during 7 months of follow-up.
