A Surgeon’s Perspective of Abdominal Wall Endometriosis at a Caesarean Section Incision: Nine Cases in a Single Institution

Abstract

Abdominal wall endometriosis in a Caesarean section scar (AEC) is an infrequent type of extrapelvic endometriosis which rarely transforms into a malignant lesion. A painful mass located in the scar of a Caesarean section is a typical sign of AEC. This condition is diagnosed preoperatively using imaging modalities such as computed tomography and ultrasonography, as well as fine-needle aspiration. Although AEC has typical signs, general surgeons often misdiagnose it due to its rarity. Herein, we report our experience of AEC in a single institution.
