Case report

A G3P1 presented to our department at 20 weeks of pregnancy. Her clinical examination of the uterine size assessment was consistent with 24 weeks of pregnancy. No fetal malformations were detectable and the biometry was consistent with the 20th week of pregnancy. Some parts of the placenta showed multiple cystic areas, while other parts looked normal. After one week the clinical size of the uterus was consistent with 28th week of pregnancy accompanied with extensive placental growth. We presumed the diagnosis of the partial mole and the parents opted for the termination of the pregnancy. Chromosomal analysis wasn"t performed, but the histological examination confirmed the diagnosis of the partial mole.
