Benign solid tumours of the kidney are rare and their anatomo-pathological features are given according to Lakey's classification. Although reports of such tumours are few (0.24%) in a wide study using abdominal echography, some post-mortem data assign an incidence of 5.2% to renal leiomyomas. The authors report a case of right kidney leiomyoma in a 69-year-old man who had undergone right radical nephrectomy. Diagnosis was only possible after the histological examination.
