We report the first case of bilateral renal solitary fibrous tumor diagnosed in a patient suffering from tuberous sclerosis.


From the bibliographic review, only 15 cases of solitary fibrous tumor have been described in the kidney. We did not find any case of simultaneous bilateral involvement. We did not find any case described in a patient with tuberous sclerosis either, as the present case, being a 51-year-old female with presenting with a big abdominal mass arising from the left kidney (25 cm) and another 2 cm mass in the right kidney.


We emphasize the extreme rarity of this tumor in the kidney. It has benign characteristics and behavior, and good prognosis, but requires surgical treatment to obtain a proper histopathologic diagnosis, based on immuno-histochemical studies.
