摘要

20歲男性患者主訴右下顎區無痛性腫塊約半年之久，於他院進行活體切片檢查，病理診斷爲下顎骨惡性肉瘤。其後患者轉診至本院，經檢查評估後接受惡性腫瘤廣泛性切除術，從下顎骨聯合處到髁頭下處切除，並以腓骨肌皮游離皮瓣重建，最終病理報告爲未分化肉瘤。術後接受輔助性放射線治療，治療過程平順。此患者至今追蹤2年，無腫瘤復發或遠端轉移之現象，因頭頸部肉瘤之預後不佳，且未分化肉瘤於頭頸部發生者又相當罕見，故在此提出並加以討論。

A 20 year-old male patient with a painless swelling mass over right mandible for half a year was presented. The incisional biopsy performed at other hospital reported a malignant sarcoma. He was later referred to our hospital. After examination and evaluation, he received operation for tumor wide excision, which resected the mandible from right parasymphysis to subcondylar region, and the mandibular defect was reconstructed with free fibula osteofasciocutanous flap. The final pathological report was undifferentiated sarcoma. Postoperatively, he received adjuvant radiotherapy for 6250 cGy. The treatment was uneventfully. The prognosis of sarcoma in head and neck region is poor. However, the patient had periodic follow up in OPD for 2 years without recurrence or metastasis. The undifferentiated sarcoma is very rare in head and neck region, so we present this case for further discussion.
