Abstract

Aneurysmal benign fibrous histiocytoma(ABFH) is a relatively rare variant and has a distinctive histopathological features, that is collections of capillaries, foci of hemorrhage, siderophages, and foamy macrophages surrounding cleft-like and cavernous blood filled spaces in the tumor. But, in spite af the distinctive features, it is not infrequently confused with malignant melanoma, angiomatoid malignant fibrous histiocytoma, and vascular tumors such as spindle cell hemangioendothelioma, nodular Kaposi's sarcoma and angiosarcoma. We report a case of ABFH developed on the left upper extremity of a 41-year-old man.
