[Localization of leiomyoma with respect to the placenta--factor for complications during pregnancy?].

We are presenting two cases of pregnant women with leiomyoma of the uterus, diagnosed antepartum. In both cases the patients were admitted on an emergency basis due to premature uterine contractions. In both cases preterm hemorrhage and fetal malpresentations were observed. The complications of pregnancy in both of the cases were primarily based on the location of the leiomyoma with respect to the placenta--intramural or submucosal disposition of the leiomyoma, retroplacentarily situated.
