Malignant tumours of the testis are reported to be rare in negroes. All cases reported in the records of the University Hospital of the West Indies and the Jamaica Cancer Registry over the period June 1958 to December 1976 were studied. There were 26 cases, giving a world standardised incidence of 0.40 per 100,000 per year. This incidence is higher than that seen in African negroes but lower than that of negroes in North America. The peak age incidence is a decade later than that commonly seen in high incidence countries.
