Multiple fibroepithelial polyps of the renal pelvis and calyces: A case report

Abstract

Fibroepithelial polyp of the renal pelvis is an extremely rare entity. We report a case of multiple fibroepithelial polyps of the renal pelvis and calyces and discuss this rare and confusing condition with its clinical, radiological and pathological findings.

A case of totally cystic fibroepithelial polyp of the renal pelvis

“…Almost 90 % of these are derived from the primitive epithelium and are transitional cell carcinomas [1,2]. Mesenchymal tumors are rare.…”

“…They are commonly diagnosed in the third or fourth decade [1,2,4,7,8,9,10]. Clinically they manifest with hematuria and flank pain [4,6,8,11].…”

“…Transitional cell types account for approximately 90 % of those derived from the primitive epithelium, whereas fibroepithelial polyps (FEP) are the more frequently encountered mesenchymal tumors [1,2]. To date, 27 FEP have been described by imaging techniques, with only one of them exhibiting a cystic component at CT [3].…”
