Solitary fibrous tumor of the kidney: A case report

DiscussionUp to now, only 105 cases of occurring renal SFT have been reported. SFTs are usually asymptomatic when they have a small size, that’s why the diagnosis is often delayed. Blood tests do not have any diagnostic value. Imaging features are not specific for the diagnosis of SFT which are diagnosed as renal cell carcinoma and treated as such. Typical immunohistochemical characteristic is a high positivity for CD34. As SFT has a malignant potential, careful follow-up is mandatory,searching for local recurrence or metastasis which was reported in few cases.ConlusionSFTs are indolent tumors and are usually diagnosed as renal cell carcinomas preoperatively and the final diagnosis is always based on immunohistochemical study.
