Abstract

A case report of fibrosarcoma arising from the mandibular incisors region.
A 31 year old male noticed a swelling of gingiva of the tongue side in the mandibular incisors for about 2 months. He underwent a tooth extraction of 12, but the swelling further aggravated accompanying spontaneous pain thereafter. He was then referred to our deparment. Soybean sized mandibular lymphonode was touched, each one on both sides, and the left one was immobile with tenderness. A granuloma-like hyperplasia of walnut size was observed in the alveolus at 213 portion, extending over the tongue side. X-ray examination revealed an osteoabsorbant image with unclear borderline over the alveolus dentalis corresponding to 2|3 portion. At outopsy, the diagnosis of fibrosarcoma was made, so that a continuous amutation at 6|6 and neck dissection on both sides were performed while the remaining mandibular was maintained with A-O plate. Homotransplantation of ilium was performed 7 months after operation. As of 3 years after operation, the patient wears false teeth in part with no recurrence. Histologically, fibrous volamentum was formed in the surroundings of tumor. Each tumor cell has a large nucleus and was composed of closely proliferate cells having irregular ellipse or spindle sporophore, forming thick and short collagenous fibers in part. In the densely arranged regon, Storiform pattern on Herring bone pattern was observed.
