title: Severe preeclampsia and fetal virilization in a spontaneous singleton pregnancy complicated by hyperreactio luteinalis.
abstract: BACKGROUNDŕ: Hyperreactio luteinalis is a rare condition that stems from theca cell hyperplasia in the ovaries due to a high level of human chorionic gonadotropin during gestation. It occurs commonly in pregnant patients with trophoblastic disease, occasionally in multiple pregnancies, and rarely in normal singleton pregnancy.
  
  
  METHODS
  A 24-year-old pregnant woman, G3 P0, who was admitted to the Perinatology Clinic with increasing findings of virilization during pregnancy was presented. The patient had bilaterally enlarged multicystic ovaries on sonographic examination and elevated serum androgen levels She was managed conservatively until 38th week of gestation as a presumptive diagnosis of hyperreactio luteinalis. Elevated blood pressure and prominent proteinuria were detected during the follow-up of the patient and labor was induced. She underwent an emergency caesarean delivery because of fetal distress. During caesarean section, ovarian biopsies were taken and a histopathological diagnosis of hyperreactio luteinalis was determined. The female fetus also presented virilization.
  
  
  CONCLUSIONS
  Although infrequent, hyperreactio luteinalis with both maternal and fetal virilization can occur in women with spontaneous singleton pregnancies. The clinical manifestations in such women may be complicated by severe preeclampsia.
