Fibroadenomas are the most common tumors in women of childbearing age, especially young women under the age of 30. The majority of biopsied ACR4A lesions correspond to adenofibromas. Usually these are solid, oval, well defined, with regular contours, lobulated (≥4 lobulations).We present the case of a 17-year-old girl, who has multiple fibroadenomas, about 36 lesions. The majority of fibroadenomas are unique, however, multiple fibroadenomas can be observed in 15-20% of cases. The average number of multiple fibroadenomas in a single breast has been reported to be 2-4. Management requires long-term follow-up.
