title: Complete hydatidiform mole and live fetus in a singleton pregnancy with confined placental mosaicism and fetomaternal hemorrhage: a case report.
abstract: BACKGROUND
  Coexistence of complete mole and a live fetus is uncommon (1:22,000-100,000), more so with euploidy.
  
  
  METHODS
  We present a case of a molar pregnancy with a euploid fetus who had close fetal evaluation for second trimester bleeding. The patient presented at 29 weeks' pregnancy with decreased fetal movements, a result of fetomaternal hemorrhage. She underwent cesarean section and delivered a live infant. By close follow-up and a multidisciplinary approach, the appropriate diagnosis and a favorable outcome were achieved. Both mother and the child at 5 years of age are doing well.
  
  
  CONCLUSIONS
  Detailed anatomic and molecular studies demonstrated a complete mole resulting from confined placental mosaicism, with molar tissue showing a single paternal allele at 8/8 informative loci, all shared with the fetus, thus this coexistent molar pregnancy was not that of a separate conceptus.
