[Objective] To describe a patient with endometrial polyps showing normal cytology that were found to be malignant only after resection. [Design] Case report. [Setting] General hospital. [Patients] A 38-year-old patient with prolonged menstruation and lower abdominal pain. [Intervention] Hysteroscopic resection of endometrial polyps. [Main outcome, Measures] Hysteroscopy showed multiple small polyps without atypical vessels. The endometrial cytological findings were normal. The diagnosis of endometrial cancer was confirmed only after an operative procedure. [Conclusions] The risk of endometrial cancer in endometrial polyps is low in premenopausal women. Because it is difficult to predict the presence of malignancy, operative evaluation of polyps should be undertaken to confirm the diagnosis.
