title: Sertoli-Leydig cell tumor of the ovary: A diagnostic dilemma.
abstract: BACKGROUND
  Sertoli-Leydig cell tumors are rare sex-cord stromal tumors of the ovary that can present with a variety of histological elements, which may complicate diagnosis and treatment.
  
  
  METHODS
  A 40-year-old female presenting with pelvic pain is found to have a large complex right adnexal mass and elevated alpha-fetoprotein. The mass was diagnosed as a Sertoli-Leydig cell tumor with heterologous elements including carcinoid and hepatoid components. She was treated with surgical resection followed by adjuvant chemotherapy and remains clear of disease.
  
  
  CONCLUSIONS
  Prognostic indicators for Sertoli-Leydig cell tumors include degree and type of heterologous element differentiation. Thorough characterization of such elements is crucial for adequate diagnosis and treatment.
