The presence of a bladder mass in a patient with inflammatory bowel disease poses a diagnosticdilemma. We present the case of a 26-year-old male with a bladder mass who had not previouslybeen diagnosed with Crohn's disease. Initial biopsies of the bladder mass were consistent with inflammatorychanges, but superficial transitional cell carcinoma could not be reliably excluded.Subsequent evaluation confirmed the presence of Crohn's disease with bladder involvement, and thepatient underwent bowel resection and partial cystectomy. Pathologic evaluation demonstratedCrohn’s disease and no evidence of malignancy. Accurate differentiation of benign and malignantbladder masses in patients with inflammatory bowel disease may be difficult and requires cooperationbetween pathologists and clinicians.
