Benign tumors of the renal pelvis are rare, with less than 10 cases reported in the literature. The fibroepithelial polyp, a benign mesodermal tumor, seems to be the most common type. We report a case of a fibroepithelial polyp of the renal pelvis, and discuss its clinical features and diagnostic pitfalls.
