title: Benign struma ovarii complicating pregnancy: a case report and review of the literature.
abstract: BACKGROUND
  Struma ovarii is a type of mature ovarian teratoma consisting mainly of thyroid tissue. The rarity of this tumor in pregnancy and the risk of malignancy make difficult the diagnosis and the management.
  
  
  METHODS
  We report a case of benign struma ovarii initially detected as an ovarian mass at the first trimester of pregnancy.
