The paper reports two case studies of abdominal wall endometriosis occurring in surgical scars after cesarean section, where patients presented with a scar mass that showed cyclic changes in size and swelling, sometimes making intraoperative palpation difficult. In each case, the authors administered a medium-dose combined estrogen–progestin oral contraceptive (Planovar®) preoperatively to allow the endometriotic mass to be reliably palpated on the day of surgery. Wide local excision with clear margins was then performed, and the masses were excised cleanly in both patients. This paper is centrally about endometriosis—specifically abdominal wall endometriosis after cesarean section and preoperative Planovar use to aid surgical identification.

Abstract

We describe 2 cases of abdominal wall endometriosis, a condition that usually occurs in surgical scars from previous cesarean sections and presents as a mass with cyclic pain and swelling. Wide local excision with clear margins seems to be the only effective treatment. However, the mass in our 2 cases changed in size with menstruation, and palpating the masses was sometimes difficult. Therefore, we administered an oral contraceptive containing a combination of estrogen and progesterone (Planovar®) preoperatively to each patient so that the endometrial mass could be reliably palpated on the day of operation. The mass was excised cleanly in each case.
