title: [Epithelial hemangioma and hemangioendothelioma].
abstract: A comparison was performed of common as well as of different marks of 5 epitheloid hemangiomas and 5 epitheloid hemangioendotheliomas. Histiocytoid features of tumour endothelial cells was obvious in both cases but a common structural basis was represented by solid epithelial buds growing from vessels of medium class and tunnelized by fusion of big cytoplasmic vacuoles. Differential diagnosis of epitheloid hemangioma was related to vasculitic processes. There were difficulties in discriminating between epitheloid hemangioendothelioma and carcinoma, malignant epitheloid Schwannoma or malignant (neurotropic) melanoma. Clinical manifestation of a skeletal manifestation of tumour concerned was mostly identical with Gorham Stout syndrome.
