A CT guided renal biopsy successfully diagnosed primary renal angiosarcoma in an 86-year-old male presenting with a necrotic renal mass, highlighting it as a differential diagnosis for such lesions.
Case Report (n=1)
Primary renal angiosarcoma is an exceedingly rare and aggressive neoplasm that should be included in the differential diagnosis of necrotic renal lesions.
Raises awareness for primary renal angiosarcoma in necrotic renal mass differentials; leaves open need for larger series to inform diagnosis and management.
Angiosarcoma of the kidney is an exceedingly rare and aggressive neoplasm. Very few cases have been reported in the English literature to date. We report a case of primary renal angiosarcoma with extensive necrosis and discuss its diagnostic difficulties. An 86-year-old male presented with a 12 cm necrotic renal mass and multiple pulmonary and hepatic nodules. A CT guided renal biopsy revealed extensive necrosis and few vascular channels lined by malignant endothelial cells. Diagnosis was given on a morphologic base and proven by an immunohistochemical study. Primary renal angiosarcoma should be included among the differential diagnosis of necrotic renal lesions.
