BackgroundTumors of the testis and paratesticular tissues are rare, especially in men of African descent. In recent reviews however, the incidence is rising among the Caucasians and black Americans. We set out to determine the incidence in South-Western Nigeria and to examine the histopathologic variants.MethodsA retrospective study of patients who had histopathologically confirmed testicular and para-testicular tumours between 1989 and 2005 (17 years). Their records were documented at the Ife-Ijesha cancer registry which serves 4.7 million men residing in three states of South-Western Nigeria.ResultsThere were 26 cases of testicular and para-testicular tumors with an average incidence of 1.5 cases per year. The incidence of testicular cancer in our study was 0.55 per 100,000 population (95% CI, 0.52-0.57) and accounted for 1.1% of all male cancers. Rhabdomyosarcomas were the most common variety (70% of the paratesticular tumors and 26.8% of all tumors of the testis). Seminomas comprised 50% of the germ cell tumors and 15.4% of all testicular tumors in this series.ConclusionThere still remains a low incidence of testis cancer in the South Western Nigeria. The reduction in the incidence of seminomas makes rhabdomyosarcomas the most predominant tumor in South Western Nigeria.
