title: Primary renal angiosarcoma mimicking a renal cell carcinoma.
abstract: Primary renal angiosarcoma is a very rare malignant tumor that closely mimics the more common renal cell adenocarcinoma (hypernephroma) in radiologic appearance. Both tumors are hypervascular masses and the diagnosis must be confirmed histologically. However, in the presence of a tumor with a capsular blood supply, and in the absence of venous invasion, the diagnosis of renal angiosarcoma may be suggested, especially in a patient with a new onset of consumption coagulopathy.
