Osteofibroma of mandible, transformed into malignant tumor, has not yet been reported. This case occured from osteofibroma that had primarily symmetrical foci in the mandible of a 2 years and 3 months old child. The osteofibroma took the secondary transformation into sarcoma in the periosteum, and brought in the diffuse metastasis on salivary. and lymphatic glands and finally on the breast. The patient finally died. This case suggested us that osteofibroma may be considered rather dangerous in the case of in fant. Histologically we observed tumorous transformation of tooth anlage (dental follicule), which made us suppose some histogenic relation to the incidence of the tumor. The present case is the first report of osteofibroma occurring symmetrically in the mandible in the literatures of our country, and the age of the victim may be the youngest described in the foreign reports. Because of the patient's infancy, and the scope of resection being very extensive, the usual splint was inapplicable as the after-treatment. We had, however, a successful result by applying the artificial mandible made of acrylic resin.
