下顎臼齒區之骨母細胞骨肉瘤-病例報告

頭頸部之骨母細胞骨肉瘤發生率極少，治療一般以手術切除爲主，化學及放射線治療的角色目前還不明確，但仍有研究報告指出是有幫助的。此疾病光靠X光診斷是極爲困難的，且臨床表現又較無特異性，故很容易做出錯誤的診斷。本病例爲一中年男性因右下顎牙齒不適合併右下唇麻痒感至本院就診，臨床初步診斷爲右下顎第一大臼齒牙根處牙堊質增生合併骨髓炎，於全身麻醉下進行切除及腐骨清除手術，病理報告爲惡性骨母細胞骨肉瘤，隨後安排患者接受廣泛性切除手術、右頸淋巴廓清手術及後續的輔助性化學及放射線治療。術後復原情形良好，目前持續於門診追縱。因病例之少見特殊性，故在此提出，並回顧相關文獻。

Head and neck osteoblastic osteosarcoma is very rare. The main treatment for head and neck osteoblastic osteosarcoma is surgical resection with wide margins, and the benefit of chemical and radiation therapy is not yet clear, but there is still research report is helpful. Diagnosis by X-ray of this disease alone is extremely difficult, and the clinical manifestations and relatively non-specific, so it is easy to make the wrong diagnosis. This case is a middle-aged male who came to our hospital with tooth discomfort in his right jaw with a right lower lip numbness. Clinical diagnosis is hypercementosis over right mandibular first molar area with osteomyelitis.
