Mucinous Micropapillary Carcinoma (Mucinous Carcinomas with MicropapillaryPattern) of the Breast: A Case Report and a Literature Review

The current study presents a mammary carcinoma characterized with both micro papillae and mucinous feature in a 43-year-old female. The patient presented with a six-month history of growing painless mass in the right breast. The patient underwent mastectomy with the ipsilateral axillary dissection and was followed-up for 10 months without any evidence of metastasis and recurrence. Except for the abundance of extracellular mucin, the current example shows a diffuse architectural pattern equivalent to the pattern seen in invasive micro papillary carcinoma. Up to now, the essence of the special subtype and the classification of the rare breast carcinoma are still controversial.
