Leiomyoma: An Exceptional Benign Tumor of the Kidney.

Renal leiomyoma is a benign finding in kidney pathology. It has been documented in various organs; renal location is less frequent and has been rarely documented in the literature. We present here the case of a renal leiomyoma revealed by an abdominal mass and flank pain. The diagnosis of certainty is histological, generally on surgical specimens. Due to the challenges associated with clinically diagnosing this tumor, a high level of suspicion is warranted when a patient presents with sizable and clearly defined renal lesions.
