Gliomyosarcoma

Abstract
The development of sarcoma within a glioblastoma is a well recognised complication: in the majority of cases it is a fibro-sarcoma originating in the tissues of the proliferating hyperplastic blood vessels. In the case described here the tumour is a rhabdomyosarcoma, apparently derived from abnormal prolific vascular mesenchyme. Only one comparable example has been recorded previously.
