Malignant hemangioendothelioma of the skin.
Three cases of malignant hemangioendotheliomas in elderly individuals are recounted. All of them died shortly after onset of the malignancies in spite of radical surgery in one; radical surgery, chemotherapy, and radiotherapy in another; and chemotherapy and radiotherapy in the third. Findings from studies of specimens of the malignancies by conventional microscopy, histochemistry, and electron microscopy are described.
