Background: Fibroma or leiomyoma is the most common benign tumor of the female reproductive system, which is usually found in the uterus, but may also occur in other places, such as the ovary, the broad ligament, and in rare cases in the abdominal wall. The formation of the abdominal wall leiomyoma may result from the implantation of myometrium tissue following surgical removal of the uterine leiomyoma, but sometimes these masses occur in a person who has no history of myomectomy. Case Presentation: This case was a patient who became a candidate for laparoscopy due to abnormal uterine bleeding and pain in the right upper quadrant of the abdomen and ovarian mass. The patient underwent laparotomy due to the inability of surgeons to insert the veress needle because of the presence of mass in the abdominal wall. The pathologic report of the abdominal mass was leiomyoma. This article has been approved by the Ethics Committee of the University (6562276). Conclusion: The formation of myoma on the abdominal wall is rare but given the fact that leiomyoma can be created at each part of the body with smooth muscles, including the anterior abdominal wall, this diagnosis should be considered for the differential diagnosis of abdominal masses.
