Abstract

Phyllodes tumor of the breast is a rare, but clinically important fibroepithelial tumor, accounting for <1% of breast tumors. Histologically, phyllodes tumor is classified into three; as: benign, borderline or malignant, based on a combination of histological and pathological criteria. This classification of the phyllodes breast tumor is precisely relevant in the clinic. While local recurrence of phyllodes tumor may occur in all grades, metastasis is mostly limited to malignant and few borderline cases, usually the latter two types having a worse prognosis of the disease. Treatment is mainly surgical as phyllodes tumor doesn´t respond well to systemic therapy. This review of the phyllodes tumor allows to guide the entire medical community based on the most recent evidence to diagnose and thus be able to manage this pathology, avoiding its complications.

Key words: Phyllodes tumor; breast neoplasms; surgery
