摘要

Schwannoma is a benign, slow-growing tumor derived from Schwann cells of the nerve sheath. The occurrence of schwannoma in the intraoral regions and hypopharyngeal regions are rare. Preoperative diagnosis of schwannoma may be suggested by imaging procedures such as MRI. However, an accurate preoperative diagnosis is difficult. Hence, histopathologic examination is still confirmatory. In this report, we present two cases of schwannomas that occurred in rare extracranial locations.

神經鞘瘤是一個良性生、長緩慢的腫瘤，起源於神經鞘的許旺細胞。臨床上它是一個單獨性的腫瘤，可以發生在身體的任何位置；顱外的神經鞘瘤多半發生在咽部，很罕見的會發生在口腔內或是咽下區域。要在手術前診斷出來神經鞘瘤是不容易的，多半是要根據核磁共振檢查的影像來臆測可能會是神經鞘瘤。通常還是要靠組織病理學的檢查才能得到一個肯定的答案。在本篇文章中我們要報告兩個罕見位置的顱外神經鞘瘤。
