Endometrial cancer (EC) is the most common malignancy of the female genital tract.1 It occurs primarily in postmenopausal women. Overall, about 2.64% of women develop EC during their lifetime. In those patients, the most common presenting symptom is abnormal uterine bleeding. Based on clinical and pathological features, sporadic EC is classified into 2 types. Type I EC, represents the majority of sporadic EC cases (70-80%). It is usually well differentiated and endometrioid in histology. Type II EC, represents the minority of sporadic EC cases (10-20%). It is poorly differentiated and usually papillary serous or clear cell in histology.
