Objective To summarize the research progress of mucinous breast cancer (MBC). Methods Literatures about the recent studies of MBC were reviewed. Results MBC was one of special subtype of infiltrating breast cancer. According to the mucus ingredient in the ratio of the mass, MBC was divided into pure mucinous breast cancer (PMBC) and mixed mucinous breast cancer (MMBC). Compared to infiltrating ductal cancer-not otherwise specified (IDC-NOS), MBC showed higher positive expression rates of estrogen receptor (ER) and progestrogen receptor (PR), with reduced lymph node metastasis rate and better prognosis. PMBC had lower lymph node metastasis rate and better outcome than MMBC. Conclusions There is significant difference about clinical and pathological characteristics between MBC and IDC-NOS. Researches are generally believed that MBC is an uncommon breast neoplasm which is associated with a good prognosis.
