[Symptomatic renal leiomyoma].

Symptomatic leiomyoma of the kidney is an uncommon, large, solitary, benign mesenchymatous tumor that must be distinguished from renal cell carcinoma. However, the diagnostic imaging techniques currently available do not permit determining the benign nature of the lesion with precision and radical excision of the compromised kidney is warranted, as in the case described herein.
