Cerebral gliosarcoma, pulmonary adenoid-cystic carcinoma, and pulmonary metastatic gliosarcoma: report of an untreated case.

An elderly woman had a cerebral gliosarcoma with a single pulmonary metastasis, together with a separate pulmonary adenoid-cystic carcinoma. Spontaneous extraneural metastases of primary intracranial neoplasms are exceedingly unusual; so far, only 8 proven cases are recorded in the English language medical literature. The association of cerebral gliosarcoma and a pulmonary adenoid-cystic carcinoma is presumably coincidental.
