A Rare Breast Carcinosarcoma in a Young Female

Metaplastic breast cancer (MBC) is a rare aggressive type of breast cancer, as this form of cancer makes up only 1% of overall breast cancers. It mainly presents with a rapid-growing mass.  Establishing the diagnosis is based on histopathology, as imaging studies show the same features as other types of breast cancer. The treatment protocol for MBC is similar to those for invasive ductal carcinomas owing to the lack of standardized management modality for metaplastic breast cancer per se.
