Abstract
BACKGROUND: Primary mucinous cystadenocarcinoma of the breast is an extremely rare entity. To the best of our knowledge, only 17 patients have been described in the PubMed database. CASE REPORT: Here, we report a primary breast mucinous cystadenocarcinoma with endocervical-like mucinous epithelium in a 62-year-old woman. The patient was followed for 5 months without any adjuvant treatment and she continues to be disease free. CONCLUSIONS: Primary breast mucinous cystadenocarcinoma usually displays unique pathologic and immunohistochemical characteristics simulating its ovarian counterparts; it seems to have a good prognosis after complete resection.
