中文摘要 | 背景:許旺氏神經瘤是一個單一發生,有包被的一個周邊神經性良性腫瘤,它很少出現於女性的外陰部。 病例報告:一位41歲女性,因外陰部腫瘤住院。理學檢查顯示右外陰部有一個大約五公分的腫瘤。外陰部超音波顯示一個3.7X3.0X 3.2cm有包被及低音波反射的腫瘤。腫瘤以手術切除,其邊緣平整且有彈性,病理切片顯示有典型梭狀細胞環狀排列。免疫化學組織檢查顯示S-100蛋白質陽性,NSE陽性,及Actin陰性反應。病理報告確認是許旺氏神經瘤。 結論:我們報告一個罕見的外陰部許旺氏神經瘤,並強調以超音波鑑別診斷外陰部腫瘤有其 一定的角色。 |
英文摘要 | BACKGROUND: Schwannoma is generally a solitary, nodular, benign tumor of peripheral nerve sheaths, and it rarely affects the external female genitalia. CASE REPORT: A 41-year-old female, G1P1, was referred to our hospital due to a vulvar tumor of about 5 cm. Sonography of the tumor revealed a well-encapsulated mass of about 3.7 × 3.0 × 3.2cm with homogenous low echogenicity The tumor was entirely resected. It had a smooth surface with an elastic consistency. Microscopically, a swirling pattern of some spindle-shaped cells and fibers were found. Interlacing bands intermingled with multiple foci of myomatous changes were also found. The ovoid and spindle-shaped nuclei dispersed in scanty cytoplasm were oriented in a palisade. Immunohistochemical studies including S-100 protein (positive), anti-neuron-specific enolase (positive), and actin (negative) were noted. These confirmed the diagnosis of schwannoma. CONCLUSIONS: Schwannoma is normally a benign tumor found in a peripheral nerve sheath. It rarely affects the external female genitalia. Sonography is seful for differential diagnosis of vulvar tumors. |
