[Pregnancy and extreme myomatous uterus--conservative management]

The management of a pregnancy complicated by uterus myomatosus remains being controversially discussed. Myomectomy early in pregnancy is opposed by exspectative management with myomectomy subsequent to the post partum period. Therapeutic abortion and exstirpation of the gravid uterus represent only hypothetical but not reasonable alternatives. Complications like ureteral obstruction, sepsis, and torsion of the uterus with subperimetrial bleeding as a cause of fever of unknown origin may occur. Rapid growth of a fibromatous uterus in pregnancy may call for a biopsy. Two cases are presented to demonstrate that with intensive pregnancy surveillance exspectative management is justified and may lead to successful confinement of the pregnancy.
