Nephrogenic Adenoma of the Bladder After Kidney Transplantation: Spontaneous Improvement with Azathioprine Removal; Surgical Trauma and Cytomegalovirus Infection as Possible Etiologic Factors

Abstract

We report 2 cases of nephrogenic adenoma several years after successful cadaver kidney transplantation. In 1 case the lesion had cytomegalovirus inclusions, and we observed a marked and sustained reduction in the extension of the lesion with cessation of azathioprine. Surgical trauma and cytomegalovirus infections are discussed as etiologic factors. Conservative treatment seemed appropriate.
