Introduction: breast cancer is the most common tumor in women and the leading cause of cancer death in this group with about 230,000 new cases per year in the United States. Adjuvant treatment of breast cancer with hormone receptor-positive tamoxifen plays a critical role but is nevertheless well known the increased risk of endometrial cancer with its use. Metastases of breast cancer to the uterus are rare but there are some cases reported in the literature. The differential diagnosis between primary tumor and distant metastases to the uterus from breast cancer determines the type of treatment that should be administered. Case: we report a case of breast cancer that presented uterine metastases during treatment with tamoxifen and demonstrate the usefulness of histopathology with immunohistochemistry to reach the diagnosis.
