Abstract

Nephrogenic adenoma is an uncommon benign lesion of the urinary

tract induced by chronic irritation of the vesical mucosa, due

to infection, trauma, surgery, calculi, foreign bodies and chemical

agents. A 68-year-old male was admitted to our linic for a periodical

cystoscopic evaluation as part of a follow-up initiated due

to a past transitional cell carcinoma. The scheduled cystoscopy

revealed, within a bladder diverticulum, an unexpected and completely

asymptomatic nephrogenic adenoma that we removed by

transurethral resection. We followed up the patient at 24 months,

then later we made the diagnosis of nephrogenic adenoma. During

this time, the patient experienced three relapses within the same

diverticulum, always involving a nephrogenic adenoma we persistently

treated by transurethral resections. As the nephrogenic

adenoma is considered a benign lesion without any direct evidence

of a possible evolution to an overt cancer, we successful

attempted a half-yearly cystoscopic follow-up to control the growth

of a highly recurrent benign entity, interposing between controls

a periodical imaging. This paper represents the second report of a

nephrogenic adenoma within a bladder diverticulum, but the first

case of a nephrogenic adenoma highly recurrent within the same

diverticulum and managed conservatively by regular transurethral

resection scheduled over the time
