UNCOMMON BLADDER-TUMORS

Among epithelial tumors, squamous cell carcinomas represent only 3 to 7% of the cases in the temperate countries, but constitute the most fr equent histologic kind in bilharzien endemic zones and 17% of intradiv erticulars tumors. The adenocarcinoma is found most often in the bladd er dome, representing only 0.3 to 3% of all bladder tumors. Invasive c ancer in a neighboring organ (digestive tract, genital organs) must be eliminated. In most cases, combining ultrasonography and intravenous urography can be helpful for diagnosis of intradiverticular carcinoma or bladder dome tumor. Computed tomography and magnetic resonance imag es are the best methods for positive diagnosis and extension explortio n for tumors of the dome and base of the bladder. In this work, we rep ort a series of five cases of uncommon bladder carcinoma. Three of the cases were intradiverticular squamous cell tumors and two were adenoc arcinoma of the bladder dome.
