Teratomas in the Igbos of Nigeria.

A study was made of the site of 86 teratomas occurring in approximately 7,500 surgical specimens received at a central laboratory serving government, mission, and private physicians working among the lgbos of Nigeria. Most teratomas [74 cases (86%] arose in the ovaries. Testicular teratoma was not seen in the series that included three testicular and 37 ovarian primary cancers. Accordingly, gonadal tumors are as uncommon in Igbo males as in other Nigroes.
