title: Mixed malignant mesenchymoma metastatic to the central nervous system.
abstract: A unique case of central nervous system metastases of mixed malignant mesenchymoma in an 84-year-old man is described. The tumor exhibited an osteogenic appearance in the cerebral lesion and a primitive mesenchymal appearance in lesions of the brain stem and cerebellum. The primary site was apparently the chest wall, and there were also metastases to the lung and liver.
