Primary renal angiosarcoma: A case report and a short review of literature.

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.
