Abstract
1. Two cases of primary skeletal haemangiopericytoma treated by ablative surgery, one in combination with radiotherapy, are reported.
2. A discussion of the management of these tumours includes surgical excision, radiotherapy, a combination of both or a combination of radiotherapy with chemotherapeutic agents.
3. Because of the unpredictable behaviour of these tumours it seems necessary to include ablative surgery if cure is to be expected.
