The incidence of bladder diverticulum is approximately 1.7% in children and 6% in adults. Dysplasia, leukoplakia, and squamous metaplasia and stone formation may develop in diverticulum and sometimes with malignant changes. The most common histological subtype of diverticulum tumors is transitional cell carcinoma (TCC). Herein we report 2 such cases of transitional cell carcinoma arising in diverticulum of the urinary bladder, one of which was associated with diverticular stones.
