Decidua and gestational trophoblastic neoplasia: a review

Abstract

Abstract

The normal endometrium changes after implantation of an embryo. Decidua is the term for the endometrium during a pregnancy, which is formed under the influence of progesterone as the maternal part of the placenta. It has a histologically distinct appearance, displaying large polygonal decidual cells in the stroma. These are enlarged endometrial stromal cells, which resemble epithelium. Interaction of decidua and trophoblasts causes many physiologic and pathopysiologic changes in the uterine cavity. Imaging of decidua and trophoblastic tissues by ultrasound is an important aspect of diagnostic workout in obstetrics and gynecology.

Özet

Desidua ve gestasyonel neoplazi: derleme

Normal endometrium embriyonun implantasyonundan sonra değişir.  Progesteron etkisi altında plasentanın anne tarafını oluşturan endometriuma gebelikte desidua denir. Stromasında büyük poligonal hücreler olması karakteristik özelliğidir. Bu hücreler epitele benzeyen büyümüş endometrial stromal hücrelerdir. Desidua ve trofoblastların ilişkisi uterin kavited birçok fizyolojik ve patofizyolojik değişikliğe neden olur. Jinekoloji ve doğum biliminin klinik uygulamasında ultrasonografi ile desidua ve trofoblastik dokuların görüntülenmesi tanısal işlemlerin önemli bir kısmını oluşturur.
