What is it about?

We present the case of a 17-year-old girl who consulted for a progressively appearing right breast mass discovered by self-palpation. Clinical examination and imaging revealed suspicious bilateral masses, classified as ACR 5 on MRI.

Why is it important?

However, biopsies showed benign lesions. Bilateral enucleation was performed. Histopathological analysis confirmed a fibroadenoma on the right and a low-grade phyllodes tumor on the left. Postoperative outcomes were favorable, with no recurrence.

Perspectives

Breast masses in adolescent girls are most often benign. Fibroadenoma is the most frequently encountered lesion in this age group. Phyllodes tumor, although rarer, may present with misleading clinical and radiological features, warranting careful management. The differential diagnosis between these two entities primarily relies on histopathological examination.
