Leiomyoma of the Renal Vein: A Rare Tumor Presenting as a Renal Mass

Abstract

Leiomyomas are benign mesenchymal tumors that rarely occur in the kidney. Renal leiomyomas usually occur in the renal cortex or capsule. They are less commonly found in the muscularis propria of the renal pelvis and cortical vascular smooth muscle. In this case report, we present a 41-year-old woman who had right flank pain and detected a mass in the right kidney hilum.

Clinical progression of renal vein leiomyoma: A case report

“…Upon extensive search of literature, only five cases of leiomyoma of renal vein were found to have been reported [1,7,[9], [10], [11]]. The displacement of viscera by the growing tumour is likely responsible for the intractable pain experienced by these patients.…”

“…While leiomyomas can occur in any organ that contains smooth muscle, they are more common in the uterus [1]. Vascular leiomyomas are of uncommon occurrence.…”

A Rare Case of Renal Leiomyoma Treated with Laparoscopic Partial Nephrectomy

“…They usually originate from smooth muscle cells of the renal capsule and, less commonly, from the renal pelvis and blood vessels (1). Although renal leiomyomas are seen in 4% to 5.5% of autopsy specimens, its clinical incidence is very low (2)(3)(4).…”
