The background of the study was the need to compare the histopathology data pool of surgical specimens of Nigerian children of the Igbo ethnic group with the published parameters of Wilms tumor (WT). This was studied at a Reference Pathology Laboratory during a period of 30 years. Interesting results included the finding that all the patients presented with abdominal swelling. The peak age was between 24 and 59 months as in a series reported from a developed country. Other interesting parameters included the bilaterality of the lesion and metastasis to the lymph nodes. It is concluded that the histopathology data pool is an etiological method for investigating the epidemiology of Wilms tumor worldwide.
