Partial mole with fetal triploidy as a cause for imminent HELLP-syndrome at 16 weeks of gestation.

A woman at 16 weeks of gestation was admitted to our perinatal center with unspecific abdominal pain. The results from blood samples 12 h after admission revealed a fulminant HELLP-syndrome. After starting i.v. corticosteroid therapy, the woman recovered quickly. CVS was performed because of abnormal findings by ultrasound and a fetal triploidy (69, XXX) was diagnosed. Pregnancy was terminated and histopathological examination of the placental tissue confirmed a partial mole.
