[Metastatic intracerebral malignant fibrous histiocytoma from the lung].

Malignant fibrous histiocytoma usually develops in the extremities, peritoneal or retroperitoneal space and the thigh. The occurrence in the lung and brain is quite rare. We report two cases of metastatic intracerebral malignant fibrous histiocytoma from the lung. The first patient developed cerebral metastasis six years after treatment of the primary site, and the second one died two months after the diagnosis of generalized metastases. Both were quite resistant to radiation therapy.
