Abstract

Seaton, D. (1974).Thorax,29, 595-598. Primary diaphragmatic haemangiopericytoma. Haemangiopericytomas are tumours consisting of vascular spaces surrounded by proliferating pericytes. Since this neoplasm was first described (Stout and Murray, 1942) over 300 cases have been reported. All tumours of the diaphragm are rare, and a primary diaphragmatic haemangiopericytoma has not been previously recorded in the English literature. Such a case is described and the features of haemangiopericytomas are discussed.
