Two bilobed placentas were obtained of woman pregnancy at 37 and 38 weeks of gestation with newborns live and examined the villous tree with light microscope. Two small lobes were found in one placenta and other in the second placenta. Two normal placentas were taken as control. Ten histological samples by each lobe were processed with H&E stain. Five biopsies by each normal placenta were taken and three histological slides by biopsy were dyed equally. Degenerative changes at level of vessels of the placental villi were noted in stem villi: stromal lysis, multiple capillarity, congestioned vessels, and increased dilatation of vessels. Regions of immature villi, pre- infarcts, deficiency of terminal villi in mature intermediate villi, destroyed villi, in immature villi the vessels are near to the syncytium indicating extensive hypoxic villous damage. In this condition a diminution of the blood flow or events of thrombosis could to be affecting the growth of these small lobules.
