“…Two further differences are detectable by using the electron microscope (Ramsey, 1966): a. the endothelial cells of the HP are essentially normal in structure and distributed along the vessels while those of the HE occur in excess numbers, have voluminous cytoplasm with many processes and irregular borders; b. a thin layer of extracellular material surrounds the vessels in HP and packs them into tight masses whereas in HE there is a much broader expanse of material separating all the cells from each other in an irregular fashion. \ Sweitzer and Winer (1936) described it as an angiomatous tumour, of the low-grade type of malignancy, which may run a benign course, Stout (1943) found it to be a highly malignant tumour. Ten of his 18 patients died, although there was a great variance in clinical course, one patient dying within 8 weeks of diagnosis, while another survived a protracted course of 20 years.…”

“…Many case reports have been excluded because of insufficient data or inadequate description. Some of those described as haemangioendothelioma have obviously been other tumours (Sweitzer and Winer, 1936;Winer and Levin, 1959) whilst others have been called benign metastasing haemangioma (Robinson and Castleman, 1936;Legg and Fitch, 1950). Froelich and Coe (1936) reviewed the literature to that date and found 26 cases, 6 of which were in the head and neck.…”
