title: [Immature teratoma of the ovary and pregnancy].
abstract: BACKGROUND
  Composing of less than 1% of all ovarian cancers, immature teratoma is a malignancy that mainly affects the young. Immature teratoma of the ovary together with pregnancy is rare. To our knowledge, this association was reported only in twelve cases.
  
  
  OBJECTIVE
  We Report two cases of immature teratoma of the ovary diagnosed during pregnancy and their respective issue.
  
  
  METHODS
  1st case. A 28 years old woman gravida 1 with an immature teratoma of the ovary discovered during delivery by caesarean section. The treatment was conservative including salpingo-oophorectomy, omentectomy, aortic lymph node dissection and appendectomy. This patient had a second pregnancy with a good outcome. She delivered by caesarean section in order to perform radical treatment: hysterectomy and oophorectomy of the remaining ovary. 2nd case. A 22 years old woman gravida 1 with adnexal mass diagnosed during an ultrasonography exam at 15 weeks gestation. A conservative treatment was indicated, including salpingo-oophorectomy, omentectomy, aortic lymph node dissection, appendectomy and biopsy of the remaining ovary. The patient had a normal vaginal delivery.
  
  
  CONCLUSIONS
  Immature teratoma is graded from 1 to 3. The management of this association is discussed, but it takes in consideration the surgical staging, the grade and the secretion of aFP. Conservative treatment without associating chemotherapy can be tempted in tumours with a stade AI and a low grade.
