摘要

神經鞘瘤(neurilemmoma)是一種源自神經外胚層，生長緩慢的良性腫瘤，主要是由周邊感覺或運動神經髓鞘上的許旺氏細胞不正常增殖所致。臨床上，神經鞘瘤可發生於任何年齡，與性別的差異；通常是一個與症狀的獨立結節，有包膜被覆並且質地較爲堅實，主要好發於四肢的屈肌表面及頭頸部的軟組織，偶爾會出現骨內神經鞘瘤個案，且主要在下顎骨，多半源自下齒槽神經。本病例報告爲一位55歲女性，於左側下顎骨體內發現一個具放射通透性的病灶，經切除手術及組織病理檢查，確認爲神經鞘瘤。有鑑於下顎骨內神經鞘瘤病例的罕見性，故提出本個案報告，並就臨床及組織病理特性及鑑別診斷上加以探討。

Neurilemmoma is a benign, relatively slow growing tumor composed of neuroectodermal derivative of Schwann cells in the peripheral nerves. It may arise at any age and there is no sex predilection. It normally presents as a solitary, asymptomatic, and well-capsulated firm mass. The tumor is mostly found on the surface of flexor area of the limbs and the soft tissue of the head and neck region. Central lesion is relatively rare. Occasionally, intraosseous neurilemmoma of the jaw has been reported, chiefly the mandible, apparently arising from the inferior alveolar nerve. Here we present a 55-year-old female with a central radiolucent lesion in the left mandibular body. Neurilemmoma was diagnosed after tumor excision and histopathologic examination. Central neurilemmoma of the jaw is rare. Only one case (this case) of neurilemmoma of jawbone was found among the 55 cases of neurilemmoma in this hospital from 1986 to 2007.
