Abstract

The antiestrogen tamoxifen is currently the most commonly used adjuvant treatment of breast cancer with antiestrogenic effect on mammary tissue. However, it is also associated with endometrial abnormalities, including hyperplasia, polyps, carcinoma, mostly interpreted as evidence of estrogenic effect on the endometrium. Previously, tamoxifen-associated polyp in breast cancer has been reported in the literature. Most studies had a long follow-up period and tamoxifen-associated polyp developed more than 1 year after tamoxifen treatment. In this case, we report an unusual case of rapid growing and multiple endometrial polyps that were developed only after 3 months' tamoxifen treatment in a postmenopausal breast cancer patient who received quadrant mastectomy with a brief review of literature.
