We studied two autopsy cases of primary pituitary carcinoma. Case-1. A 45 year old female was admitted on Oct. 4 1978, with a complaint of right homonymous hemianopsia. And diagnosis was pituitary adenoma. Partial removal of pituitary tumor was performed on Oct. 23 1978. She died on Dec. 5 1978 due to bleeding of gastrointestinal tract. Autopsy disclosed a pituitary carcinoma invading the left hypothalamus, mamillary body, optic and V cranial nerves, and mid brain as well as sphenoid bone. No extracranial metastasis was noted. Case-2. A 44 year old female with a history of acromegaly for 6 years was admitted with a complaint of headache on May 8 1976. She was diagnosed as having pituitary adenoma. The subtotal removal of pituitary tumor was performed on May 21 1976 and followed by 4500 rad irradiation. At this time, pathological diagnosis was eosinophilic adenoma. Seven years later, she complained of progressive right hearing disturbance, dysarthria and ataxic gait 1983. The second subtotal removal of pituitary tumor was performed with a diagnosis of recurrence of pituitary adenoma on Oct. 7 1983. After the operation, she complicated sepsis and died on Jan. 14 1984. An autopsy disclosed a pituitary carcinoma from residual pituitary gland, continuously extending to the subarachnoid space of the pons, and invading right cerebello-pontine angle and cerebellum. The histological examination revealed pituitary carcinoma with high pleomorphism and glioblastoma multiform-like feature were within the tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

A 67-year-old male presented with a clear cell ependymoma with symptoms of ataxic gait and dizziness. Magnetic resonance imaging showed a ring enhanced and circumscribed mass lesion with some cysts in the left cerebellar hemisphere, and the vertebral artery angiogram showed the vascurality of the tumor fed by both the left posterior inferior cerebellar artery and the left superior cerebellar artery mainly. They demonstrated suspicious finding of metastatic tumor, glioblastoma, or cystic meningioma. Surgery via the left suboccipital approach revealed a whitish and solid tumor, which was demarcated from the cerebellar parenchyma and had no continuity with the 4th ventricle. Total resection of the tumor was successfully performed. The hematoxilyn-eosin staining of the surgical specimen was similar to hemangioblastoma or oligodendroglioma, however, immunohistochemical findings for glial fibrillary acidic protein, vimentin, epithelial membrane antigen, and factor VIII were compatible with clear cell ependymoma. The patient's postoperative course was uneventful, and his symptoms improved. Clear cell ependymoma is known as a variant of ependymoma, which is usually located at the foramen of Monro. We think that the immunohistochemical study is highly helpful for the diagnosis of the cerebellar tumor with atypical presentation such as our case.
