[Solitary fibrous renal tumor: a case report and review of the literature]

Solitary fibrous tumors are mescenchymal neoplasms which develop from connective tissue. They rarely occur in the kidney and to our knowledge only 11 cases have been reported in the literature so far. We herein report a solitary fibrous tumor of the Kidney in a 60-year-old patient presenting with renal colic. CT scan revealed a tumor in the renal hilum. The patient was subjected to total nephrectomy, and histological examination of the excised tissue showed fusiform cellular fibrotic proliferation. Immunohistochemistry confirmed the diagnosis by showing positive CD 34 and bcl-2 markers
