    A 52-year-old man presented with irritative lower urinary tract symptoms and was diagnosed with diffuse nephrogenic adenoma after multiple evaluations.

  • 2

    Cystoscopy revealed numerous papillary tumor-like lesions and bladder-wall thickening, leading to decreased bladder capacity.

  • 3

    Histopathological evaluations showed suppurative inflammation and granulation-tissue proliferation, confirming the diagnosis of nephrogenic adenoma.

  • 4

    The patient underwent radical cystectomy and orthotopic ileal neobladder substitution due to severe bladder contracture and quality-of-life impairment.

  • 5

    Post-surgery, the patient reported improved voiding intervals and resolution of pain, with normal renal function and no evidence of hydronephrosis.
