Invasive ductal carcinoma of the breast presenting with endometrial metastases in two patients

Abstract

We present 2 patients with invasive ductal carcinoma of the breast who had metastases to the endometrium. Both patients presented similarly with abnormal uterine bleeding. Gynecologic metastases are very infrequently seen amongst breast cancer patients, and even less frequently in patients with invasive ductal carcinoma by comparison to invasive lobular carcinoma. Our cases highlight the importance of considering metastatic disease as a potential diagnosis when breast cancer patients present with uterine bleeding.
