Adult Mesoblastic Nephroma: A Case Report

Mesoblastic nephroma is a rare entity in adulthood. We report a case of mesoblastic nephroma in a ۳۵-year-old woman who presented with left flank pain. Computed tomography images favored a soft tissue mass in the upper pole of the left kidney. The lesion was excised and sent for pathological analysis. Pathological and immunohisto- chemical studies favored a diagnosis of mesoblastic nephroma.
