摘要

許旺氏細胞瘤是由神經支持細胞所產生的良性腫瘤，在神經所在之處都可能產生，頭頸部的發生率約為25－40%，但在口內的發生率約為1%。本文提出1名22歲女性案例：病人因吞嚥異物感兩週而來門診就醫，自述舌部有一突出狀異物，未伴隨舌頭麻木以及疼痛感，經全身麻醉取出腫瘤，術中觀察到腫瘤邊界清楚有囊膜，可以完全與舌部肌肉分離，後續追蹤術後傷口恢復良好，無明顯復發情形。診斷上之影像學檢查包括電腦斷層以及核磁共振，對於鑑定良性以及惡性腫瘤十分重要，但在良性腫瘤的鑑別診斷之中較無惡性腫瘤重要，治療上舌部良性腫瘤還是以經口手術完全切除為主，手術後併發症最常見為舌部麻痹以及味覺異常。因病例罕見，故提出討論舌部許旺氏細胞瘤之表現以及鑑別診斷。

Schwannomas are nerve sheath tumors which are derived from Schwann cells. The head and neck region accounted approximate 25%-40% of schwannoma growth. However, only about 1% of the tumor occurred in the mouth. The aim of this study is to present a case report of tongue schwannoma and review literature of this rare tumor. We report a case of 22-year-old female with tongue schwannoma. She complained of foreign body sensation when swallowing and a protruding mass in her tongue without numbness and painful sensation. Excision of the tumor was performed under general anesthesia. No recurrence was noted one month to date. Currently, transoral excision of tumor is the standard procedure of benign lingual tumors. Tongue numbness and taste disturbance were the most common complications encountered following surgery. After critical review of the literatures, we found 70 cases worldwide with this diagnosis. We also describe the most relevant epidemiological and clinical characteristics of this kind of tumor.
