Figure 2: Tumors of vascular origin. (a) Cavernous haemangioma composed of vessels varying in size and shape (H&E, objective 20x). (b) Capillary hemangioma composed of small, rather uniform vessels (H&E, objective 20x). (c) Large-vessel hemangioma composed of intercommunicating vascular structures (H&E, objective 20x). (d) Epithelioid angiosarcoma characterized by round cells with vesicular nuclei with prominent nucleoli (H&E, objective 40x). (e) Kaposi-like hemangioendothelioma composed of spindle cells around vascular structures (H&E, objective 40x). (f) A particular staghorn appearance of the haemangiopericytoma (H&E, objective 40x).
