翼狀窩之紡錘狀細胞橫紋肌肉瘤-病例報告

Spindle Cell Rhabdomyosarcoma of Pterygoid Fossa - Case Report

摘要


橫紋肌肉瘤為兒童和青少年時期最常見的軟組織惡性腫瘤,預後並不理想。橫紋肌肉瘤依其病理組織分為4種類型:多形性(pleomorphic)型、肺泡(alveolar)型、葡萄狀(botryoid)型和胚胎(embryonal)型。近年來多位學者從胚胎型橫紋肌肉瘤中,另外分類出一種病理組織中80%以上由單一種紡錘狀細胞所組成而且預後較佳,稱為紡錘狀細胞橫紋肌肉瘤。本科於1997年3月經歷1例主訢右側臉頰麻木合併三叉神經麻痺之病例,檢查後發現右側翼狀窩有一直徑達6cm的腫瘤,在惡性腫瘤診斷的臆斷下,經Caldwell及Luc氏手術作切片診斷;病理證實是屬於紡錘狀細胞橫紋肌肉瘤。由於病例特殊,提出報告。(中耳醫誌 1998;33:158-161。)

並列摘要


Rhabdomyosarcoma is the most common sarcoma of childhood and adoles-cence with poor prognosis. Spindle cell rhabdomyosarcoma, a subtype of embryhonal rhabdomyosarcoma, has been recognized in recent years due to a different pathologi-cal picture and a better survival rate when compared to classical embryonal rhab-domyosarcoma. We experienced a 31-year-old female patient suffering from right trigeminal numbness and trismus of two months dura-tion, and diagnosed as spindle cell rhab-domyosarcoma after biopsy. Radiotherapy and chemotherapy were given due to intracranial invasion and multiple lung metastases. We should be highly aware of this disease in order to begin treatment as early as possible.
