Objective:
Scar endometriosis is a rare condition. We report a case of scar endometriosis occurring at the site of an old cesarean section scar.
Case Report:
A 29-year-old multiparous woman complained of painful sensation during menstruation for 2 years that occurred at the site of her cesarean section surgical scar. On examination, there was a firm nodule measuring 2 x 1.5 cm in size at the mid-point of the scar. In view of the possibility of scar endometriosis, the mass was completely excised. Pathologic findings were compatible with scar endometriosis. Postoperatively, danazol was prescribed to prevent recurrence.
Conclusion:
A surgical scar becoming painful and swollen during menstruation is the classic symptom of scar endometriosis. Causes include iatrogenic transplantation of endometrium to the surgical wound. Surgical excision is the main treatment. Postoperative GnRH-agonist or danazol may be prescribed to patients with scar endometriosis.
