title: Malignant haemangiopericytoma of the pelvic retroperitoneum.
abstract: A case of malignant haemangiopericytoma of the pelvic retroperitoneum is described. The patient finally died of the complications of radiotherapy. In the absence of any reported long term benefits of adjuvant radiotherapy to the lesion, the lower morbidity of chemotherapy may make this form of adjuvant therapy worthy of further evaluation.
