Papillary (transitional) carcinoma in an ileal conduit

Abstract

An example of papillary carcinoma developing at the ureteroileal junction with herniation of the tumor into the lumen of an ileal conduit is reported. This and similar tumors have occurred within 4 years of urinary diversion, emphasizing the need for continued surveillance of patients with an ileal conduit. Patients with widespread atypia of the transitional epithelium of the urinary tract, such as ours, are especially prone to recurrent carcinoma and should be watched most carefully. Surgical excision of the tumor occurring at or near the ureteroileal junction should always include a cuff of ileum, as in the standard treatment of renal pelvic and ureteral tumors.
