Abstract

Placental mesenchymal dysplasia is a rare placental abnormality. Placenta is found to be enlarged with cystic villi and dilated thick vascular structures. Importance of this abnormality is the clinical and morphological similarity to the partial hydatidiform mole and presentation with Beckwith- Wiedemann syndrome. Our case was diagnosed as partial hydatidiform mole in her rutin pregnancy controls. This is the 20. case in literature that had not any extra-placental abnormality.
