<\/span><\/h2>\nEpithelioid<\/span> hemangioma is a benign<\/span> vascular<\/span> injury<\/span> of the skin or deeper structures (bone). Has many similarities with angiolymphoids hyperplasia<\/span> with eosinophilia<\/span> and some authors believe that they are the same entity. Although eosinophils<\/span> they are often rich in injury, peripheral<\/span> Eosinophilia is not a feature. <\/p>\n<\/span>\nHistology<\/span> epithelioid hemangioma<\/span>
\n<\/span><\/h2>\nIn epithelioid hemangioma, histopathologically<\/span> there's a proliferation<\/span> of blood vessels<\/span> with epithelioid endothelial<\/span> cells (Figures 1,2). Endothelial cells are thick and abundant. eosinophilic<\/span> cytoplasm<\/span> sometimes it resembles histiocytes<\/span> (Best seen in figure 2.) Because the endothelial cells are so thick, it is sometimes difficult to appreciate the vascular spaces and aggregates<\/span> it may look like granulomas<\/span>. Accompanying vascular proliferation are collections of lymphocytes<\/span> numerous eosinophils (Figures 1,2).<\/p>\n\n<\/span>Pathology of epithelioid hemangioma<\/span><\/h5>\n<\/section>\n\n\n
