Tuberose sclerosis with malignant astrocytoma.

A case is described of a recurrent malignant gemistocytic astrocytoma in which a diagnosis of tuberose sclerosis was made at post-mortem examination, when "rhabdomyomata" were found in the cardiac muscle and tubers in the cerebral hemispheres. Malignant degeneration of a cerebral lesion has not been described in association with tuberose sclerosis.
