Case Report: A 15-year-old girl with no family history of breast cancer presented with two masses in the left breast. The excisional biopsy on both lumps revealed juvenile fibroadenoma and juvenile papillomatosis epithelial proliferation multiple cystic expanded channels. In some of these channels, cytological features of intraductal carcinoma were observed. We performed a full immunohistochemical examination of the juvenile papillomatosis. The patient refused any further surgical or adjuvant treatment. There are no signs of recurrence in the 15 year follow-up. Discussion: This case is a diagnostic and therapeutic challenge, taking into account the patient's age and the controversial treatment recommendations. Good collaboration between surgeons and pathologists is essential for an accurate diagnostic process and aims to avoid under- or overtreatment.
