Renal Leiomyoma
Introduction
Renal leiomyoma is a rare benign tumor that is found in approximately 5% of the specimens from autopsy. This tumor may arise from smooth muscle cells of the renal capsule, the muscularis of the renal pelvis, or cortical vascular smooth muscles, with the renal capsule being the most common site. Renal leiomyomas are most commonly found in white women. Most leiomyomas are small and are asymptomatic. Large leiomyomas may manifest with a palpable flank mass and pain.
