Abstract
A 21 aged male suffered from headache, pain in the neck, convulsion and change of character for about 3 months. Ventriculogram showed dilatation of lateral and third ventricles. He died on 27 days after ventricular-drainage.
A hemorrhagic solid tumor measured 5×4×4cm replaced pineal gland and distended along the posterior wall of the third ventricle. Microscopic examination showed variable picture of teratoid tumor, squamous stratified epithelium, glands lined by columnar epithelium, angiomatous tissue, adenocarcinoma and undifferentiated carcinoma, so-called pinealoma and choriocarcinoma.
Subpleural multiple small hemorrhagic foci of both lungs showed, microscopically, metastatic picture of choriocarcinoma.
