Abstract

Objective: Unusual clinical course Background: There are few reports of breast cancer cases with uterine metastases; among them, myometrium is more frequently involved than endometrium. The majority of breast cancer metastases to endometrium are lobular type, and there have been only 5 reported cases of ductal type since 1984. Here, we describe a new case of invasive ductal carcinoma with metastases to endometrium and isolated presentation of abnormal uterine bleeding, in addition to reviewing the existing literature on other similar cases. Case Report: The patient was a 51-year-old Persian woman with no remarkable past medical or family history of cancer, who presented with a 6-month complaint of menorrhagia to our gynecology clinic. Diagnostic studies including trans-vaginal ultrasonography, pathological examination of endometrial curettage specimen, immunohistochemistry findings, and X-plane and magnetic resonance mammography, and breast core-needle biopsy revealed invasive ductal breast carcinoma as the origin of the endometrial metastasis. Conclusions: Abnormal uterine bleeding in a premenopausal patient should alert clinicians to the possibility of secondary as well as primary neoplasms. It is necessary to differentiate a metastatic tumor from a primary one, since the treatment and prognosis are completely different. © Am J Case Rep.
