LARGE PLACENTA

It occurs in Syphilis, diabetes mellitus, largest in erythroblastosis fetalis. This kind of placenta is greasy in appearance and nearly one quarter of the weight of the Fetus

PLACENTA SUCCENTURIATA

IN this placenta one or more small accessory lobes lie away from the main mass and connected to it by membranes containing umbilical vessels.. It leads to Sever PPH, sub involution, uterine sepsis, polyp formation

PLACENTA MEMBRANACEA

IT Result from the faliure of the chorion leave in contact with the decidua capsularis to degenerate. It is very thin and and large placenta occupying a large area on the uterine wall

PLACENTA CIRCUMVALLATA

In this condition an opaque ring is seen on the fatal surface of the placenta. It is formed by a doubling back of the chorion and amnion and may result on the membranes leaving the placenta nearer the center instead at the edge as usual

BATTLEDORE PLACENTA

IN this the cord is attached to the margin of the placenta and not at the center

PLACENTA ACCRETA

IT is an abnormal partial or total adherence of placenta to the uterine wall in other words the placenta is directly adhered to the myometrium with either defective decidua or no decidua in between

PLACENTA INCRETA

In this the muscle or myometrium have been invaded by the villi, in this placenta and uterine wall become one solid continuous mass

BIPARTITA /DIMIDIATA

IN this condition the division of the placenta into two distinct lobes is incomplete. The umbilical vessels extent from one lobe to the other before they unite to form the umbilical cord

TRIPARTITA PLACENTA

IT is similar to the BIPARTITA placenta but three distinct parts. There are three complete lobes of placenta

PLACENTA VELAMENTOUS

In this placenta umbilical cord is attached to the membrane usually one - three inches away from placenta. It is rare type. It may cause APH during artificial or spontaneous rupture of membrane

PLACENTA FENESTRATA

IN this placenta the aperture of varying Sizes near its center. It causes division of the placenta into two lobes

PLACENTA MARGINATA

In this placenta, there is depression near the center of Fetal surface.. It is surrounded by a thickened whitish ring
