[Pregnancy in a woman with Turner syndrome--two new cases].

Pregnancies resulting from a spontaneous ovulation and fertilization are extremely rare in women with Turner syndrome. The majority of them end with abortion, still-born, or neonates with congenital defects. The article presents two women with Turner syndrome, mosaic karyotype 45,X/46,XX, who got pregnant without any medical intervention. The course of one pregnancy was complicated by imminent premature delivery, pyelonephritis and anaemia. Because of the lack of progress and threatening infection, the delivery was conducted by caesarean section in 40th week of pregnancy. Healthy male neonate was born. The other patient gave birth in 38th week of pregnancy to a healthy baby boy, by caesarean section, because of lack of progress in delivery. Children develop correctly. It is important to note, that despite distinct clinical features, in first patient Turner syndrome was identified 3 years after delivery.
