Gastric cancer in augmentation gastrocystoplasty

A 27-year-old man operated for myelomeningocele in the neonatal period and for augmentation gastrocystoplasty at age 13 years for voiding dysfunction, was diagnosed with gastric adenocarcinoma on the stomach side of bladder augmentation. A radical cystectomy and an ileal conduit procedure were performed and the pathologist confirmed a poorly differentiated gastric adenocarcinoma. Urologists should be aware of this potential degeneration, and long-term follow-up is mandatory to detect malignization of these cystoplasties.
