Adenocarcinomas are uncommon tumors of the urinary bladder. accounting for 0.5% to 2.2% of all bladder malignancies over world.

Separating urachal tumors from non-urachal tumors are important in their prognosis. Authors report thirty-nine cases analyzed according to their clinical aspects at presentation and according to their gross and histopathologic features, such as location, size, shape, stage, d1fferentiation, cell types on microscopic examination. Twenty-one tumors were primary; 8 tumors were non-urachal, 11 tumors were urachal and others from colon, stomach, rectum and ovary. Urachal tumors. In histopathologic types fo primary adenocarcinoma in the urinary bladder, adenocarcinoma, NOS are most common. In urachal adenocarcinomas, enteric types cystitis cystica, cystitis glandularis, necrosis and calcification are also seen. But around urachal tumors, cystitis cystica and cystitis glandularis are not observed.

Sometimes, routine clinical and pathologic study cannot differentiate the histogenesis and the classification of adenocdarcinoma in the urinary bladder. Further studies are needed.
