Squamous cell carcinoma and transitional cell carcinoma arising in bladder augmentations

Tumours arising in bowel-augmented bladders are rare. Usually these tumours are adenocarcinomas that occur along the anastomotic line. We present two unusual tumours, squamous cell carcinoma and transitional cell carcinoma, that occurred in bladder augmentations. We also emphasize the need for regular cystoscopic surveillance.
