[Extraordinary case of malignant phylloid tumor of the breast: surgical reconstruction treatment].

Phyllode tumors of the breast are fibroepithelial tumors similar to fibroadenomas but with a predominant conjunctive tissue component. They are rare with an incidence of less than 1% of all breast neoplasms. They can be divided in three categories: benign, borderline, malignant. The Authors report the case of a 53 years old woman who presented an exceptional 6.5 kg phylloid tumor of the left mamma. The diagnostic strategies, the surgical total mastectomy procedure with anterior thoracic parietectomy and the surgical reconstructive treatment are described.
