A comparative study of ovarian tumours in black and Indian patients.

An analysis of 426 primary ovarian tumours in Black and Indian patients in Natal shows a disparity in the incidence of cystomas and teratomas in the two groups. Cystomas comprise 29% of all ovarian tumours in Blacks compared with 67% in Indians. Germ cell tumours, however, predominate in Blacks, comprising 52%, as opposed to 19% in Indians. The Indian distribution is similar to that of American and European groups.
