**10. Closing remarks**

All the menstruating women or postmenopausal, especially using hormone replacement therapy, in whose cases any lesion in any postoperative scar or nearby them appear, should be suspected of endometriosis. It should be kept in mind that lesions of an abdominal wall or another regions of the body even without operation in past might be of endometriotic origin. In unclear cases additional proper diagnostic examinations are advised preoperatively.

The wide excision of the lesion with possible fascial or muscular repair should be offered in these cases and histopatological examination ought to be performed by an experienced histopathologist because of a possibility of malignancy. One should remember that diagnostic pitfalls, particularly among general surgeons often occur.

Medical treatment being less invasive than the surgical one, may be developed and seems to be promising in the future.

Unnecessary operations, especially cesarean sections, should be avoided and if performed, one should be aware of the transmission of endometrial cells in the wound.

Further systematic investigations in the field of scar endometriosis are still needed.
