Sixty-one cases of adenocarcinoma of the urinary bladder presenting between 1966 and 1981 were reviewed. Among the only seven cases of primary adenocarcinoma of the urinary bladder, three were classified as primary signet-ring cell carcinoma. These 3 cases were reviewed with the 11 previously reported cases in the literature. Primary signet-ring cell carcinoma of the urinary bladder occurs predominantly in men (12 men, 2 women) with age ranging from 38 to 83 years. It usually runs a rapidly fatal course despite therapy. The characteristic clinical, gross, and histomorphologic findings and pathogenesis of this rare bladder malignancy are discussed.
