中文摘要 | 骨原性肉瘤是好發於青春期的惡性骨腫瘤,發生率約十萬分之一,好發年齡二十餘 歲,好發部位為四肢長骨,尤以股骨遠側幹�情A脛骨近側及肱骨幹�惇隻h,其特徵為大量局 部骨破壞及易有早期肺臟轉移,預後很差,曾有文獻報告五年存活率為 20%,至於頭頸部的 骨原性肉瘤就更為少見,美國統計為每年十萬人口中有 0.07 個病例,約佔全部骨原性肉瘤 的 6.5%。本院於民國 85 年 6 月經歷一右側下頜骨的骨原性肉瘤病例,接受右側下頜骨及 顳頜關節切除術及人工顳頜關節重建術,手術後因傷口感染而將人工顳頜關節取出,傷口癒 合後可以進食流質及半流質飲食,至今無復發跡象。 |
英文摘要 | Osteogenic sarcoma is principally a malignant bone tumor frequently found in teenagers The incidence is about 1/10,000. The age of predilection is in the second and third decades of life. The tumor occurs most often in the long bones, with a predilection for the distal femoral metaphysis, proximal tibial, and humeral metaphysis. Due to massive bony destruction and early lung metastasis, the mortality of the tumor in these locations is high, with a 5-year survival rate of only 20%, Osteogenic sarcoma originating from head and neck regions is rare, wiht an incidence or about 0.07/100,000, which accounts for 6.5%of all cases of osteogenic sarcoma. We encountered such a case, which is presented as follows. A 78-year-old woman suffered from swelling wiht tenderness over right side parotid area and trismus. Open biopsy revealed osteogenic sarcoma of the mandible. She refused surgical intervention at first, so chemotherapy was given. No improvement was noted after two courses of chemotherapy, And then she received night side hemimandibulectomy and temporomandibular joint replacement with metal prothesis in September 1996. After surgical treatment, the temporomandibular joint metal prothesis was removed due to wound infection. The patient could take in liquid and semi-liquid diet after wound healing. There is no evidence of recurrence so far. |
