肺癌浸潤が上大静脈症候群のみを主徴とした一剖検例

A rare autopsy case; Lung carcinoma infiltration manifests only SVC syndrome

　進行した肺癌が上大静脈の圧迫閉塞を起こすことはしばしば経験することであるが，原発部位に腫瘤をつくるに至らぬうちに，上大静脈内に浸潤穿通，腫瘤を形成，完全閉塞し，しかも右房内に大きく伸展していた症例を経験したので，考察を加えて報告する。

A case of 43 year old housewife who manifested with superior vena cava syndrome and chronic cardiac tamponade deceased while etiologic diagnosis was not established.

Autopsy revealed that it was due to the invasion of bronchogenic carcinoma (undifferentiated adenocarcinoma) which mainly extended into the walls of IVC, innomiate veins and RA without showing any other organs. No such case was found in the auther's literature review.
