Nephrogenic adenoma with bladder exstrophy and immunosuppression

Nephrogenic adenoma, an unusual proliferative lesion, often occurs in association with chronic inflammation of the bladder and is rarely found in children. Two cases are reported, one occurring in a young child born with bladder exstrophy, and one in a young female, with both interstitial cystitis and chronic use of immunosuppressive therapy. We believe these are the first case reports of nephrogenic adenoma occurring in this specific clinical setting.
