Renal leiomyosarcoma of the renal pelvis cannot be accurately diagnosed preoperatively via clinical presentation or imaging, making wide surgical excision the treatment of choice.
Wide surgical excision is the recommended treatment for renal leiomyosarcoma of the renal pelvis, as preoperative clinical and imaging findings are often non-diagnostic.
Preoperative diagnostic uncertainty supports wide excision for suspicious renal pelvic masses; leaves open validation of improved imaging in prospective cohorts.
We report a case of renal leiomyosarcoma arising from the renal pelvis with immunohistochemical confirmation of the diagnosis. In this instance clinical presentation and imaging finding are not helpful in accurately establishing the diagnosis preoperatively. Wide surgical excision would appear to be the treatment of choice.
