title: Malignant transformation of abdominal wall endometriosis to clear cell carcinoma: case report and review of the literature.
abstract: OBJECTIVE
  To report a case of clear cell carcinoma in abdominal wall endometriosis after cesarean section.
  
  
  METHODS
  Case report.
  
  
  METHODS
  A French oncology center.
  
  
  METHODS
  A 38-year-old woman who developed a 10-cm mass in the abdominal wall muscles, 13 years after a cesarean section.
  
  
  METHODS
  Abdominal wall resection and chemotherapy.
  
  
  METHODS
  Clinical outcome.
  
  
  RESULTS
  The diagnosis of clear cell carcinoma in abdominal wall endometriosis was confirmed, and wide surgical excision with abdominal wall reconstruction was performed after three courses of chemotherapy.
  
  
  CONCLUSIONS
  The malignant transformation of abdominal wall endometrioma has not been clearly elucidated, owing to its rarity. However, the eventuality should always be considered, and the prognosis improved through wide surgical excision.
