Scar endometriosis is an uncommon condition in which endometrial tissue grows at a previous surgery wound site. The triad of scar endometriosis includes the history of cesarean section or any other gynaecological surgery, cyclical waxing, and waning pain accompanied by the patient’s menstrual cycle and a tumor inside/near the scar site. Here, we present a case report in which the patient presented with endometriosis at the previous cesarean section scar site. She had classical clinical and imaging characteristics for scar endometriosis. However, histopathology was not diagnostic for the same. The pathogenesis, presentation, diagnosis, and management are discussed briefly. The diagnosis of scar endometriosis is based on clinical presentation and imaging. Fibrosis on histopathology is an important component of endometriosis that cannot be overlooked.
