Why the study?
Primary renal angiosarcomas are uncommon tumors with unknown etiology, difficult imaging discrimination, and controversial treatment protocols.
Primary renal angiosarcoma is a rare tumor requiring immunohistochemistry for diagnosis, with nephrectomy and chemo/radiotherapy as the main treatment options.
Requires IHC to differentiate rare renal angiosarcoma from RCC; leaves open evidence-based management strategies.
Primary renal angiosarcomas (AS) are uncommon tumors with poor prognosis. Aetiology is unknown but some unproven risk factors have been described. It is difficult to discriminate these masses from renal cell carcinomas or other renal masses with imaging modalities. Immunohistochemistry plays an important role in the diagnosis. Main treatment protocol for primary renal AS is still controversial and nephrectomy with chemotherapy and/or radiotherapy seems the only treatment option. We state a primary renal angiosarcoma case for its rareness and contribution to literature.
