Abstract: The clinicopathological features of 5 cases of micropapillary pattern of pure mucinous carcinoma (MPPPMC) of the breast were analyzed retrospectively. In this group, 5 cases of MPPPMC were all premenopausal women, whose age ranged from 37 to 48 years old. 3 cases had axillary lymph node metastasis, 3 cases had modified radical mastectomy, 1 case had breast conserving and sentinel lymph node biopsy, 1 case had breast conserving and axillary lymph node dissection, 1 case had oral endocrine drug and radiotherapy, 4 cases had oral endocrine drug and chemotherapy and radiotherapy, and 2 cases had oral targeted drug herceptin treatment. MPPPMC pattern is a kind of special type of pure mucinous carcinoma and invasive micropapillary carcinoma. The age of onset of this type is younger than that of mucinous carcinoma, and the prognosis of this type is worse than mucinous carcinoma. Whether it is an independent subtype of breast invasive micropapillary carcinoma or mucinous carcinoma has not reached consensus.
