	~~== Epidemiology ==~~		'''Molar pregnancy''', also known as '''hydatidiform mole''', is a rare complication of pregnancy characterized by the abnormal growth of trophoblastic tissue, which normally develops into the placenta. It is a type of [[gestational trophoblastic disease]] (GTD) and can be classified into two types: complete and partial moles.
	Molar ~~pregnancies are rare~~, ~~occurring in approximately 1 in 1~~,~~000 pregnancies. They are more common in women at~~ the ~~extremes~~ of ~~reproductive age and those with~~ a ~~previous history~~ of ~~molar pregnancy~~.

	== ~~Symptoms and Diagnosis~~ ==		==Types==
	*Molar pregnancies often present with symptoms of pregnancy such as missed periods, positive pregnancy test, morning sickness, and rapid uterine enlargement. However, some distinguishing features include unusually severe morning sickness, spotting or bleeding, and the absence of fetal heart tones.
	*Diagnosis is confirmed by an ultrasound which shows a "snowstorm" or "bunch of grapes" appearance due to the presence of multiple cysts. Additionally, serum human chorionic gonadotropin (hCG) levels are markedly elevated.

	== ~~Treatment and Follow-Up~~ ==		===Complete Molar Pregnancy===
	~~Treatment involves the removal of~~ molar tissue ~~from~~ the uterus~~, usually by suction dilation and curettage (D&C)~~. ~~After evacuation, it's important to monitor hCG levels regularly until they normalize, as persistent or increasing hCG levels can indicate the presence~~ of ~~gestational trophoblastic neoplasia (GTN),~~ a ~~serious but treatable complication of molar pregnancy~~.		A complete molar pregnancy occurs when an egg with no genetic material is fertilized by a sperm. The resulting tissue is abnormal and forms a mass in the uterus. There is no formation of a fetus in complete moles.

	[[Category: ~~Women's Health~~]]
			==Diagnosis==
			Molar pregnancy is typically diagnosed through:
			* Ultrasound: A "snowstorm" pattern may be seen in complete moles.
			* Elevated hCG levels: Higher than expected for the gestational age.

			==Treatment==
			The primary treatment for molar pregnancy is the surgical removal of the molar tissue through dilation and curettage (D&C). After removal, hCG levels are monitored to ensure that all molar tissue has been removed and to detect any potential development of [[gestational trophoblastic neoplasia]].

			==Prognosis==
			With appropriate treatment, the prognosis for molar pregnancy is generally good. However, there is a risk of developing gestational trophoblastic neoplasia, which requires further treatment.

A '''molar pregnancy''' is an abnormal form of pregnancy where a fertilized egg develops into a mass of abnormal cells, instead of a viable fetus. It is a type of gestational trophoblastic disease (GTD).

== Classification ==
*Molar pregnancies are classified into two types, '''complete''' and '''partial'''.
*'''Complete moles''' occur when an egg without a nucleus is fertilized by a sperm. Instead of forming an embryo, all the placental tissue grows into a mass of cysts, resembling a cluster of grapes. Complete moles usually have no normal fetal tissue.
*'''Partial moles''' result when two sperm fertilize a normal egg, leading to an abnormal placenta and an abnormal fetus. The fetus usually has severe defects and cannot survive.

== Epidemiology ==
Molar pregnancies are rare, occurring in approximately 1 in 1,000 pregnancies. They are more common in women at the extremes of reproductive age and those with a previous history of molar pregnancy.

== Symptoms and Diagnosis ==
*Molar pregnancies often present with symptoms of pregnancy such as missed periods, positive pregnancy test, morning sickness, and rapid uterine enlargement. However, some distinguishing features include unusually severe morning sickness, spotting or bleeding, and the absence of fetal heart tones.
*Diagnosis is confirmed by an ultrasound which shows a "snowstorm" or "bunch of grapes" appearance due to the presence of multiple cysts. Additionally, serum human chorionic gonadotropin (hCG) levels are markedly elevated.

== Treatment and Follow-Up ==
Treatment involves the removal of molar tissue from the uterus, usually by suction dilation and curettage (D&C). After evacuation, it's important to monitor hCG levels regularly until they normalize, as persistent or increasing hCG levels can indicate the presence of gestational trophoblastic neoplasia (GTN), a serious but treatable complication of molar pregnancy.
