Nephrogenic adenoma of the bladder in renal transplant patient –⁠ case report

Overview

Nephrogenic adenoma (NA), also referred to as nephrogenic metaplasia, is a rare benign lesion affecting the urinary tract . The development of this lesion is attributed to the implantation of isolated renal tubular epithelial cells in areas of damaged transitional epithelium, often associated with prior instrumentation of the urinary tract . Clinical symp toms are nonspecific, commonly manifesting as hematuria (both macroscopic and microscopic), pollakisuria, and painful urination . Notably, during endoscopic examination, these lesions can be eas ily misinterpreted as malignant tumors . This publication presents two case reports of NA found in the urinary bladder of adult patients after kidney transplantation, the NAs faithfully mim icked urothelial carcinoma during cystoscopic and radiological examination
