Two autopsy cases of primary choroid plexus tumor and review of the 200 cases histolcgically diagnosed as the primary choroid plexus tumor and reported since 1833 are described. 1. Case 1 : A 28 days old female. She had an enlarged head (45.5 cm in circumference) at birth and was diagnosed as a hydrocephalus. At autopsy, the tumor was approximately 5×5 cm and located at the posterior wall of the left lateral ventricle. Microscopical examination revealed a benign choroid plexus papilloma. 2. Case 2 : A 62 years old male. Clinically, cauda equina symptom was noticed and metastases of adenocarcinoma were found in the lumbar spinal cord and cauda equina by lumbar laminectomy. At autopsy, the tumor appeared to fill the third ventricle, and showed diffuse metastases to the bilateral cerebellopontine angle, subarachnoid space of the cerebellum, nerve roots of the spinal cord, etc. Microscopically the tumor had a papillary structure with a vascular connective tissue stroma and nuclear pleomorphism, and invaded the third ventricular wall and cerebellum. 3. Of the 200 cases of the choroid plexus tumor, 34.0 per cent were found in the first decade and 80.9 per cent of these were located in the lateral ventricles. In the other decades 50.8 per cent were present in the fourth ventricle. Of sixty-one cases of carcinoma or papilloma with metastasis including the present case (case 2), twenty-five of these occurred in the first decade.
