title: Abnormal vaginal bleeding from endometrial polyps in a woman receiving tamoxifen therapy for breast cancer: report of a case.
abstract: We report herein the case of a women receiving tamoxifen therapy for breast cancer who developed vaginal bleeding, subsequently found to be caused by unusual endometrial polyps. Upon presentation, ultrasonography and magnetic resonance imaging (MRI) demonstrated a tumor within the uterus. A hysterectomy was performed, and macroscopic examination showed polyp-like lesions of the uterus. Histologically, these polyps demonstrated cystically dilated glands and stromal proliferation, and were diagnosed as endometrial polyps. Although tamoxifen has few side effects, any signs or symptoms of gynecological abnormalities should be carefully evaluated in patients on long-term tamoxifen therapy.
