Gestational Trophoblastic Disease
54
A placental abnormality marked by trophoblastic
proliferation and hydropic degeneration of the
chorionic villi.
Hydatidiform Mole
55
Results from abnormal fertilization, where all of the chromosomes are paternal in origin due to a loss of maternal chromosomes from the zygote at the time of
fertilization.
Complete Hydatidiform Mole
the fetus cannot be identified in the
amniotic sac
56
Evolve from oocytes fertilized with two
spermatozoa, therefore, the cells have 69
chromosomes, one set from the mother, and
two sets from the father. This combination is
also lethal, but the embryo does not die
immediately, so parts of the embryo are found
encased among the hydropically altered
placental villi and normal placental tissue.
Incomplete Hydatidiform Mole

solid Sex Cord Stromal Tumors that secrete Estrogens. They are always benign and often cause menstrual irregularities and endometrial hyperplasia.
Thecomas
90
solid Sex Cord Stromal Tumors composed of cells resembling granulosa cells of the ovarian follicles. These also produce estrogens that can cause menstral irregularities. The small tumors are benign, whereas the larger tumors may be malignant. These can cause
precocious puberty in young girls and in older
women can lead to breast or endometrial cancer.
Granulosa Cell Tumors

| reaction in the uterine endometrium.
Decidual Reaction
98
It is considered to be the “growth hormone” for the fetus.
Human Placental Lactogen (hPL) is a protein
hormone that induces lipolysis, thus elevating
the levels of free fatty acid in the mother.
99
steroid hormones produced by the placenta, but their function is unknown in the fetus and mother.
Estrone, Estradiol (the most potent), and Estriol
100
used by the fetal adrenal cortex as a
precursor for glucocorticoid, testosterone
(males), and mineralocorticoid synthesis.
Progesterone
101
The fetal membranes present as a thick ring, rolled and raised over the fetal surface instead of at the edge of the placenta. (the chorionic plate is smaller than the basal plate of the placenta). The blood vessels at the chorionic plate stop at the raised membranes and continue to run deeper under the membranes.
Circumvallate Placenta

104
This finding within the umbilical cord is an abnormal
finding that suggests cardiovascular
abnormalities.
The presence of one umbilical artery
105
The Umbilical Cord is inserted into the fetal membranes and not the placenta, hence the unprotected umbilical vessels run for some distance between the amnion and chorion before passing on to the placental surface. (found in about 1% of deliveries)
Velamentous Insertion of Umbilical Cord
106
The umbilical cord becomes
coiled around the neck, again caused by
movement of the fetus through a loop of cord.
Nuchal Cords
107
Elevated levels are associated with Neural Tube
Defects (Spina Bifida, Anencephaly, etc.) and
esophageal and duodenal atresias (these interfere
with fetal swallowing). Reduced levels are
associated with Down Syndrome (Trisomy 21).
Alpha-Fetoprotein or AFP produced by the
| fetal hepatocytes.
108
Excess amniotic fluid is removed via the
placenta and passed into maternal blood. Swallowing defects (esophageal atresia) or absorption defects (duodenal atresia) results in
Polyhydramnios
109
A low amount of amniotic fluid (<400ml in late pregnancy). It may be associated with the inability of the fetus to excrete urine into the amniotic sac due to
renal agenesis or an obstructive uropathy.
OLIGOHYDRAMNIOS
110
a lack of amniotic fluid can cause the amniotic cavity to be too small, can cramp the growth of the fetus, and can cause various congenital malformations such as
Potter’s Syndrome or hypoplastic lungs
| due to increased pressure on the fetal lungs.
111
Occurs when there is a large amount of amniotic fluid (>2000 ml in late pregnancy). It may be associated with the inability of the fetus to swallow due to various
conditions
POLYHYDRAMNIOS
112
A partially or wholly implanted placenta in the
lower uterine segment overlying the internal
cervical os in its most severe form (Grade IV).
Placenta Previa
113
Owing to the absence of decidua, the placenta
does not separate normally from the
underlying uterine wall following delivery, an
event that can be associated with life-
threatening hemorrhage.
Placenta Accreta
114
Type of Placenta Accreta
the attachment of villi to the level of the myometrium without further invasion.
Placenta Accreta
115
Types of Placenta Accreta
The villi invade into the underlying myometrium.
Placenta Increta
116
Types of Placenta Accreta
The villi penetrate into the full-thickness of the uterine wall.
Placenta Percreta
117
• Defined as blood between the basal plate of the
placenta and the uterine wall.
• One of the most common causes of perinatal
mortality, accounting for 8% of perinatal deaths.
Retroplacental Hematoma
118
With more extensive spread, the umbilical cord,
may also become infected (funisitis), and can
exhibit vasculitis of the umbilical vessels with
neutrophilic infiltration after extension of
Wharton’s Jelly.
Chorioamnionitis
119
Infection of the villi results from endometritis
or transplacental passage of organisms
delivered by way of the maternal circulation.
(hematogenic spread)

123
Define amnion nodosum
Nodosa-Numerous small, gray or yellow nodules on the fetal surface which may be associated with Oligohydramnios ( too little amniotic fluid) and renal agenesis (Potters Syndrome-Renal Agenesis)
124
Right and left umbilical arteries carry (deoxygenated or oxygenated?) blood from the fetus to the placenta

deoxygenated blood
Oxygenated blood
125
the normal volume of the embryonic fluid at term.
o At birth volume = 1L, rate of exchange within amniotic sac = 400-500ml/hr
o Fetus swallows 400ml of amniotic fluid daily and excretes 500ml or urine at term
126

Schiller duval bodies is seen in the endodermal sinus pattern of yolk sac tumors
Consists of a central vessel surrounded by tumor cells, and the whole thing is contained in a cystic space and lined with flattened tumor cells. It represents an attempt of the tumor to form a yolk sac.
Also most common testicular cancer in children
