Cesarean section scar endometriosis: a case report and review of the literature.

ABSTRACT

Cesarean section scar endometriosis is a rare event. The reported incidence is 0.03-1.7 per cent. Herein, the authors report a case of a 35-year-old woman, G1P1, who presented with cyclic pain at the left lateral edge of the pfannenstiel scar. The skin of this edge had also become dark brown. She had undergone a cesarean section for cephalopelvic disproportion four years previously. Physical examination revealed only mild tenderness and a dark brown nodule at the left lateral edge of the scar. Pre-operative diagnosis was scar endometriosis, surgical excision was performed and the tissue pathology confirmed the characteristic features of endometriosis. The post-operative course was uneventful, and no recurrence was found during the two-year follow-up period. The literature regarding cesarean section scar endometriosis was reviewed.
