Primary abdominal wall endometriosis: presentation of rarely seen two cases.

Abdominal wall endometriosis is a pathology which usually develops after preceding surgeries on the surgical incision line and shows clinical manifestation especially during menstrual cycle. However, primary abdominal wall endometriosis is seen very rarely and it is a condition developing without a previous history of surgery. In this paper, we aimed to provide a contribution to the theories of pathogenesis of the disease by presenting two cases of primary abdominal wall endometriosis in two patients without previous history of surgery.
