肌上皮瘤源於唾腺腺泡周圍之肌上皮細胞，在頭頸部好發於主要或口腔黏膜之次要唾液腺，有梭狀細胞(spindle)、類漿細胞(plasmacytoid)、類上皮細胞(epithelioid)或清澈細胞(clear)等不同細胞分型；生長形態分為固型(solid)、黏液形(myxoid)、網狀(reticular)或混合形(mixed type)。本院於1998年4月經歷一主訴漸進性左側鼻塞二個多月之病例，理學檢查可見佔據鼻道、源自鼻中隔上端、表面平滑之腫瘤，電腦斷層掃描可見相鄰骨結構並未受到破壞，故安排病患手術。藉鼻內視鏡經鼻腔摘除腫瘤，病理報告為肌上皮瘤；因發生部位罕見，為國內首見，特提出報告。

Myoepitheliomas orginate from epithelial cells around the acini of salivary glands. They affect major or minor salivary glands of the head and neck. Cytologically, these myoepitheliomas are composed of spindle, plasmacytoid, epithelioid, or clear cell types, while architecturally they display either solid, myxoid, reticular, or mixed growth patterns. In April 1998, we encountered a 53-year-old male who had suffered from left side nasal obstruction progressively for more than 2 months. Physical examination revealed a smooth surface mass which originated from the mucosa of the upper part of the nasal septum and occupied the common meatus. CT scan showed that the surrounding bony structure was intact. We extirpated the mass by endoscopic endonasal approach; and the pathological report was myoepithelioma. The prognosis was good, and there was no recurrence of the disease after 1 year of follow-up.
