Abstract

Renal angiomas or angiosarcomas range from pinpoint size to over 10mm in diameter, are reddish and ill-defined, and usually have a subcapsular or capsular location. Large tumors may contain variously sized hemorrhagic cysts or areas of necrosis. Angiomas and angiosarcomas are distinguishable basically by cytologic criteria. Cellular pleomorphism and irregular pseudopapillary structures are a hallmark for sarcomas, as detailed by Cardesa et al. (1973).
