A Giant Juvenile Fibroadenoma in a 12-Year-Old Girl: A Case for Breast Conservation

Abstract

A 12-year-old girl presented to our service for evaluation of a rapidly enlarging 16 cm breast mass. The mass was removed by local excision and diagnosed to be a giant juvenile fibroadenoma. She had normal breast development over a 1-year postoperative follow-up period. We present this case to illustrate the diagnosis and management of large breast tumors in the adolescent age group, and to emphasize that these tumors are almost always benign and should be treated with breast-conserving surgery.
