33歲女性併發閉孔神經纖維瘤疑似卵巢輸卵管附屬器腫瘤：罕見案例併PRISMA系統性文獻回顧

Neurofibroma involving obturator nerve mimicking an adnexal mass in a 33-year-old woman : a rare case report and PRISMA-driven systematic review

閉孔神經纖維瘤是一種來自許旺式細胞（Schwann cells）的良性軟組織腫瘤。閉孔神經纖維瘤常被分類在I型神經纖維瘤病（NF-1, Von Recklinghausen's disease）。閉孔神經纖維瘤常被發現在不同的解剖位置，但很少在後腹膜腔。我們報告一個33歲女性患有骨盆腔神經纖維瘤，其擬似附屬器腫瘤。這是一個系統性文獻回顧。

A neurofibroma is a benign soft tissue tumor arising from Schwann cells. Neurofibromas have been classically associated with neurofibromatosis type I (NF-1,Von Recklinghausen's disease). They are found in diverse anatomical locations but seldom in the retroperitoneal location. We report this case of a pelvic neurofibroma in a 33-year-old woman, which mimicked an adnexal mass on presen-tation. A systematic review was conducted to identify published relevant reports.
