The final, formatted version of the article will be published soon.

Adolescent breast hypertrophy is a rare and persistent condition that affects peripubertal females both physiologically and psychologically. We present a case of a 14-year-old patient with bilateral giant breast enlargement who underwent a successful reduction mammoplasty of 16.5% Body Weight. The right breast exhibited focal interstitial proliferation myofibroblasts, suggesting a potential risk for phyllodes tumor development. This finding represents a novel histopathological association, unreported in the literature and first documented in China.
