源發自膀胱之惡性許旺氏腫瘤-病例報告及文獻回顧

Malignant Schwannoma Arising from Urinary Bladder: A Case Report and Review of Literature

摘要


我們報告一例源發自膀胱的惡性許旺氏腫瘤的少見病例,患者為一83歲男性,因腹部逐漸腫大有三個月之久而入院,經一系列檢查包括靜脈尿路攝影,大腸鋇劑攝影及電腦斷層掃瞄等檢查,顯示一巨大囊狀腫瘤佔劇整個下腹腔。經由剖腹手術發現一個20X15 cm,具完整被膜且源自膀胱壁的腫瘤,經過光學顯微鏡及組織免疫化學特殊染色,證實為一惡性許旺氏瘤。手術後追蹤一年,病人情況穩定。
