原発性気管腺癌の1例

A case of primary tracheal adenocarcinoma

Ⅰ．はじめに

　原発性気管癌は全悪性腫瘍中の0.04～0.1％^1,2）とされる稀な疾患で，われわれ耳鼻咽喉科医が遭遇する機会は少ない。さらにその組織型は，扁平上皮癌と腺様囊胞癌が大部分を占めており，腺癌の報告は少ない。今回われわれは，原発性気管腺癌の1例を経験したので，文献的考察を加えて報告する。

　A 67-year-old woman complained of dyspnea and was treated as bronchial asthma during 2 months. Endoscopic and CT scan examination revealed a mass in the right wall of the trachea. Total laryngectomy with bilateral paratracheal neck dissection was performed. Histological examination of excised specimens revealed adenocarcinoma. After the surgery, no recurrence was observed for 9 months.
