Endometrial cancer is the ۶th most common cancer in women worldwide. Rarely does occur in the postpartum period. Fifteen cases of endometrial cancer in the postpartum period have been reported before, but the diagnosis of endometrial carcinoma as a cause of secondary postpartum hemorrhage is hardly predicted. A ۳۷-year-old, Para ۴, presented two weeks after a cesarean section and had recurrent vaginal bleeding. The patient was treated conservatively. While being observed, vaginal bleeding still occurred with more volume. We decided to perform a total abdominal hysterectomy. Histopathology confirmed a low-grade endometrioid carcinoma of the corpus uteri. Endometrial cancer might cause a secondary postpartum hemorrhage, with the hypothesis that the depth of tumor invasion into the uterine muscle causes a distorted tissue architecture and the formation of new blood vessels that easily disrupt. The most common type of endometrial cancer in a postpartum woman is low grade with  a favorable prognosis.
