Vesical nephrogenic adenoma is a rare, benign entity that appearsmost commonly in middle-aged males. Its etiology is unknown,but it has been linked to chronic irritating factors, such as infection,trauma, urological surgery, kidney stones, foreign bodies andchemical agents, such as Bacille Calmette-Guerin. We report 2new cases with a history of transurethral resection of the bladderand the prostate and a history of prolonged voiding symptoms. Inboth cases, the findings of encysted tubular structures lined withflattened cuboidal cells without atypia were consistent with thediagnosis of vesical nephrogenic adenoma.
