Malignant fibrous histocytoma producing spinal cord compression.

Three cases of malignant fibrous histiocytoma presented as primary paraspinal tumours causing extradural spinal cord compression. Study of these cases suggests that pain relief is considerable after laminectomy but pain may recur with further tumour growth. Total removal is unrealistic and diagnosis, difficult. The prognosis in terms of continuing neurological deficit after surgery followed by local radiotherapy appears poor.
