title: Exclusive nodal recurrence after treatment of degenerated parietal endometriosis.
abstract: OBJECTIVE
  To report a case of endometriosis degenerated into clear cell carcinoma with positron-emission tomography (PET) scan staging.
  
  
  METHODS
  Case report.
  
  
  METHODS
  University hospital.
  
  
  METHODS
  A 43-year-old woman diagnosed with endometriosis degenerated into clear cell carcinoma with nodal metastasis at the initial diagnosis and exclusive nodal recurrence 6 months after surgery.
  
  
  METHODS
  Resection of the mass with partial resection of the pubic symphysis and bilateral external iliac lymphadenectomy. Forty-five days later, hysterectomy with bilateral adnexectomy and then adjuvant chemotherapy and abdominal-pelvic radiotherapy.
  
  
  METHODS
  The PET scan showed positive lymph nodes in the cervical, supraclavicular, bilateral axillary, bilateral inguinal, and lumbar-aortic regions.
  
  
  RESULTS
  The patient experienced a tumor recurrence after 6 months. After surgical management, she was scheduled to receive six cycles of rescue chemotherapy. She died 22 months after the initial diagnosis.
  
  
  CONCLUSIONS
  The use of PET scan could allow better staging at the initial diagnosis and improve follow-up in such patients. The treatment of this entity is based on radical surgery associated with adjuvant chemotherapy and radiotherapy, but the results are not satisfactory.
