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.
