肺・脳転移をみたAlveolar soft-part sarcomaの1例

A Case of Alveolar Soft-part Sarcoma with Lung and Cerebral Metastasis

I．はじめに

　alveolar soft-part sarcomaはChristophersonら^1）により，その組織学的特徴をとらえられ，はじめて記載されたものである．しかしその組織発生についてはいまだ不明である．最近われわれは右下腿に発生したalveolar soft-part sarcoma摘出後，肺，脳，更に脳へと3度にわたる転移をみたが，いずれも全摘出し軽快をみた1例を経験したので，若干の文献的考察を加え報告する．

A 37-year-old housewife who had episodes of surgical removal for an alveolar soft-part sarcoma of her right leg 15 years ago, and total removal for right lung metastasis 2 years ago, was admitted to our service with complaints of headache, vomiting, dyscalculia and recent memory distrubance which started about 4 months prior to admission. Neurological examination revealed papilledema and disorientation. Left carotid angiography and CT scan showed a ball-like vascular tumor in the left frontal lobe. Presumptive diagnosis of metastatic brain tumor in the left frontal lobe was made in our service.
