Abdominal Wall Endometrioma in Previous Cesarean Section Scar: Case Report

Endometriosis is defined as the presence of functional endometrial tissue, glands and stroma outside the uterine cavity, mainly at ovaries and at pelvic peritoneum, causing a chronic inflammatory reaction. The abdominal wall endometrioma is an infrequent pathology; occurs after abdominal surgery, by minimal invasion, open surgery or gin-obs surgery. It happens in about 0.03 to 1.5% women after having a cesarean section, presenting transvaginal bleeding, endometrial ultrasound with 9 mm thickness and uterine myomatosis, having a painful node at the infra-umbilical abdominal scar, with skin colour change and due to increasing pain is diagnosed with an incarcerated hernia. Urgent surgery was performed, finding a 6 × 6 × 4 cm vesicle, with brownish secretion, attached to the muscular aponeurosis. Conclusion: Not every node or bulge within the abdominal wall should be considered hernia. in the scenario of a painful node and skin colour change at a surgical scar, with a medical history of cesarean section, hysterectomy and laparoscopic procedures, diagnosis of endometriosis should be considered and therefore always perform histopathological exams.
