Background: Bladder tumor represents the second most frequent cancer of the urogenital tract after prostate cancer. The frequency of squamous cell carcinoma is higher in Africa due to the bilharzian endemic. In Western countries, urothelial carcinoma accounts for over 90% of bladder tumors. The aim of this study was to report the histological types of bladder tumors while describing the epidemiological profile of the patients.

Materials and methods: This was a retrospective study conducted in our center over the period of 4 years from January 2015 to December 2018. This study collected histopathological data of patients follow-up for bladder tumors. The samples examined were mainly biopsies and surgical specimens. The parameters studied were: age, sex, histological type, infiltrative or noninfiltrative nature of the tumor and prognosis.

Results: The mean age of the patients was 55.6 ± 14 years (18 months - 81 years). The sex ratio was 2.1. Urothelial carcinoma was the most frequent histological type (51.5%). Squamous cell carcinoma was found in 32.3% of the patients. The majority of tumors were infiltrative (66.2%). Urothelial carcinoma had a poor prognosis and was classified as high grade in 81% of the patients.

Conclusion: Urothelial carcinoma was the most frequent histological type found in our study contrary to the usual data. In the majority of cases, it was infiltrative and had a poor prognosis; hence the importance of prevention.
