Adolescent breast masses in Nigerian Igbos.
In the Igbos of Nigeria, most adolescent breast masses were due to gynecomastia in males and to fibroadenoma in females. The peak ages for both diseases differed from those reported in a recent American series. An exotic finding was a mammary mass due to onchocerca worms. Curiously, there were as many as two cases of a rare tumor, namely, alveolar soft part sarcoma.
