title: Serous adenocarcinoma of the inguinal region arising from endometriosis followed by a successful pregnancy.
abstract: BACKGROUND
  Inguinal serous carcinoma arising from endometriosis is an unusual cancer. It is uncertain how patients with these tumors should be managed, especially those patients who desire future fertility.
  
  
  METHODS
  We present a 34-year-old woman with a right groin mass with cyclical pain. Resection of this mass revealed complex atypical hyperplasia, well-differentiated endometrioid adenocarcinoma, and serous carcinoma within a focus of endometriosis. The patient desired to maintain her fertility and was treated conservatively. She is currently 3 years free of disease after diagnosis. She also had one successful pregnancy.
  
  
  CONCLUSIONS
  This is a rare case of carcinoma arising from endometriosis. The long-term prognosis for this patient remains unclear and the patient will require long-term follow-up.
