Abstract

Metastatic recurrence is a significant problem in patients with breast cancer, the most frequently diagnosed malignancy and the second leading cause of cancer-related death among women worldwide. Although the incidence of distant relapse has reduced and improved survival rates, 20–30% of patients with early breast cancer still die of metastatic disease. Breast cancer (BC) rarely metastasizes to the female reproductive system and when it does, ovaries are more frequently affected than other sites. BC metastasis to the endometrium is extremely rare and origin from Invasive ductal carcinoma (IDC) with endometrial polyp metastases which is even more uncommon than Invasive lobular carcinoma (ILC). We present a rare case of endometrial polyp metastases from IDC and reviewed the only 25 cases in the literature so far.
