Metaplastic breast cancer. A case series.

Special type breast cancers display a wide range of different histological types in which clear recommendations on clinical and therapeutic management still lack and most of the information available derive from case report and case studies. In particular metaplastic breast cancer (MBC) is a rare and aggressive type of breast cancer accounting for around 1% of breast malignancies. We reported our experience in the management of five patients with MBC diagnosed and treated in our institution during the last few years (2016-2020). KEY WORDS: Metaplastic breast cancer, Special type breast cancers.
