title: Adolescent breast masses in Nigerian Igbos.
abstract: 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.
