Structural changes within the placenta are observed in the course of pathological pregnancy. The aim of the study was to perform initial assessment of morphological features of placenta. The analysis was conducted by Scanning Electron Microscopy. Samples of placenta of women who delivered neonates appropriate for gestational age were characterized by a homogenous surface texture with natural corrugation. The surface of IUGR placenta from the group of mothers with pregnancy induced hypertension was definitely heterogeneous - noticeable swelling of tissue surface was observed. Samples from LGA group also demonstrated a number of surface bulges and heterogeneities which were, nonetheless, characterized by a certain repeatability.
