We treated two patients with a rare metaplastic carcinoma of the breast. Patient 1:A 32-year-old woman presented with a rapidly growing mass( 7cm) in her right breast. We diagnosed cT3N0M0 Stage IIB breast cancer and performed a radical resection. The pathological diagnosis was triple-negative metaplastic carcinoma with a Ki-67 value >30%. Postoperative adjuvant chemotherapy and radiotherapy were performed. Patient 2:A 66-year-old postmenopausal woman presented with a left breast mass. We diagnosed cT1N0M0 Stage I breast cancer and performed a radical resection. The pathological diagnosis was triple-negative metaplastic carcinoma with a Ki-67 value >30%. Postoperative adjuvant chemotherapy was performed. Patients 1 and 2 have achieved relapse-free survivals of 1 year+2 months and 10 months, respectively. Metaplastic carcinoma of the breast is a rare tumor, and its prognosis is not favorable. The only available treatment is that used for invasive ductal carcinoma;a more specific treatment has not been established. The accumulation of further similar cases and the development of a novel effective treatment are desired.
