摘要

神經鞘瘤雖非罕見之腫瘤，但是發生於後咽壁之神經鞘瘤則十分稀少，截至目前國外文獻僅有4例報告。通常發生於成人，罕見惡性變化，完全切除後，幾無復發之可能。光學顯微鏡下，於Antoni type A區域可見特徵的Verocay氏體。於電子顯微鏡下之超微構造可見腫瘤細胞呈典型之竇狀結構與由纖維長間隔膠原構成的Luse氏體。本病例為一男性，41歲，意外發現右側口咽後壁上有一神經鞘瘤。經口切除後，並無任何吞嚥、發聲或局部神經學上的問題，追蹤迄今並無局部復發跡象。

Neurilemmoma is common in the head and neck. However, its occurrence at the posterior oropharyngeal wall is very rare. Neurilemmomas usually occur in adults, but seldom become malignant. After complete excision, recurrence is rare. Under light microscope, Verocay body of the Antoni type A area is the characteristic finding of the tumor. Ultrastructurally, the tumor cells reveal typical sinusoidal pattern and characteristic Luse bodies consisting of fibrous long-spacing clolllagen. We herein present a case of right posterior oropharyngeal neurilemmoma. After transoral excision of the tumor, there is no swallowing, phonation or focal neurological deficits noted. No evidence of recurrence is noted in the follow-up five months.
