“…The occurrence of endometriomas in laparotomy scars, especially those following cesarean section, is sufficiently rare to warrant reporting. There have been a number of good reviews of the literature by Nicholson,1 Heaney,2 Lemon and Mahle, 3 Vassmer,4 Pratt,5 and more recently Hosoi and Meeker,6 which indicate that there are less than a hundred such reports available. Hosoi and Meeker,6 who have collected eighty-seven cases of endometriomas occurring in laparotomy scars, report only twenty-one in which the pregnant uterus had been opened.…”
