鼻中隔混合腫瘍の1例

A MIXED TUMOR OF THE NASAL SEPTUM

　I．はじめに

　"いわゆる唾液腺型混合腫瘍"は，耳鼻咽喉科領域では，大唾液腺とくに耳下腺に多くみられ，その他口唇，舌，口蓋，扁桃，咽頭などの口腔粘膜下の小唾液腺にもみられることがある。しかし唾液腺型混合腫瘍が鼻中隔に発生することはきわめてまれである。最近われわれは鼻中隔に発生したいわゆる唾液腺型混合腫瘍の1例を経験したので，その概要を述べるとともに，2,3の文献的考察を加え報告する。

　A case of mixed tumor, so-called salivary gland type, on the right nasal septum is reported.

　A housewife, aged 38, complaining of nasal obstruction was admitted to the ENT Service of the Tottori University Hospital.

　Examination revealed a dark reddish mass completely obstructing the right nasal cavity. This mass was successfully removed throughintranasal approach. The true nature of the growth was confirmed by microscopic examination.

　The patient has remained well for these five years without signs of recurrence.
