Among epithelial tumors, squamous cell carcinomas represent only 3 to 7% of the cases in the temperate countries, but constitute the most frequent histologic kind in bilharzien endemic zones and 17% of intradiverticulars tumors. The adenocarcinoma is found most often in the bladder dome, representing only 0.3 to 3% of all bladder tumors. Invasive cancer 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 images are the best methods for positive diagnosis and extension exploration for tumors of the dome and base of the bladder. In this work, we report a series of five cases of uncommon bladder carcinoma. Three of the cases were intradiverticular squamous cell tumors and two were adenocarcinoma of the bladder dome.
