肺原発上皮筋上皮癌の1例

Pulmonary Epithelial-myoepithelial Carcinoma；Report of a Case

はじめに　肺原発上皮筋上皮癌は非常にまれな腫瘍である1）．不完全切除により再発をきたすことがある2～4）とされるが，われわれは，経気管支鏡的な腫瘍切除により腫瘍が残存したため手術を施行した症例を経験した．術後再発なく5年を経過したので報告する．

A 30-year-old female was admitted for diagnosis of an abnormal shadow on chest X-ray. A computed tomography scan showed honeycombing in bilateral dorso-basal segments of the lung and a tumor obstructing the orifice of right middle lobe bronchus. Resection of the tumor by a bronchofiberscope was performed. However, a part of the tumor remained in the bronchus. Histlogical examination confirmed the tumor to be epithelial-myoepithelial carcinoma. In order to assure a complete resection of the tumor, we performed right middle wedge bronchoplastic lobectomy. The patient is doing well, without recurrence 5 years after surgery.
