title: [So-called epithelioid hemangioendothelioma].
abstract: Tumour that developed in the armpit of a 52-year-old man was studied by light and electron microscopy. The tumour 3 cm in diameter was firmly attached to the vessel and almost completely obliterated its lumen. Histologically the neoplasm closely resembled the metastasis of mammary gland carcinoma. However electron microscopic examination allowed rejecting the epithelial origin of tumour and suggesting its vascular genesis (so-called "epithelioid hemangioendothelioma").
