Leiomyomas are the most common benign tumors with an incidence of 2 to 4% of the reproductive tract in women of childbearing age. Myomectomy is the most common surgical operation performed. In a study that reviewed 10 years of experience in doing myomectomy during the cesarian section, about 0.89% had myomectomy. Although the Cesarian myomectomy rate is currently increasing, many doctors are reluctant to perform Cesarian myomectomy, due to potential associated risks, particularly the perioperative hemorrhage. It has been documented that a single CM is associated with a higher rate of bleeding when the leiomyoma diameter is more than 75 mm. We reported the case of a 26-year primigravida at 38 weeks of gestation who presented with prevaginal leaking and pain abdomen. We found it to have a huge mass over the posterior wall. A Cesarian myomectomy was performed. Histopathologically it was proven to be a fibroid uterus.
