title: Cesarean scar endometrioma: Case series.
abstract: OBJECTIVE
  To evaluate endometrioma located at cesarean scatrix.
  
  
  METHODS
  Medical data of 6 patients who presented to our institution with abdominal wall endometrioma were evaluated retrospectively and reviewed literature in this case series. The diagnostic approaches and treatment is discussed.
  
  
  RESULTS
  All patients had a painful mass located at abdominal scars with history of cesarean section. The ages ranged from 31 to 34 and Doppler ultrasonography (US) detected hypoechoic mass with a mean diameter of 30 mm. Initial diagnosis was endometrioma in 4 and incisional hernia in 2 of 6 patients. Treatment was achieved with surgical excision in 5 patients, and one is followed by hormone suppression therapy with gonadotropin.
  
  
  CONCLUSIONS
  Malignant or benign tumors of abdominal wall and incisional hernias should be kept in mind for diagnosis of endometrioma. Imaging methods like doppler US, computed tomography and magnetic resonance imaging should be used for differential diagnosis. Definitive diagnosis can only be made histopathologically. The treatment should be complete surgical excision and take care against intraoperative auto-inoculation of endometrial tissue in order to prevent recurrences.
