What is the difference between a complete and a partial hydatidiform mole?

What is the difference between a complete and a partial hydatidiform mole?

Genetics + more: A complete mole is formed when a sperm fertilizes an empty egg & duplicates, or when two sperm fertilize an empty egg. It has 46 chromosomes (all paternal). A partial mole develops when two sperm (or one sperm that duplicates) fertilize an egg & has 69 chromosomes. Fetal parts are usually only found in partial moles. Complete moles inc risk for choriocarcinoma (a type of tumor) more than partial moles.

Moles (Definition)

A mole (also called a nevus) is a localized overgrowth of pigment-producing cells (melanocytes) in the skin. Most moles are benign. However, these cells can become cancerous. This is known as melanoma, ...Read more

Is hydatidiform mole hereditary?

No.: A hydratidiform mole occurs in a molar pregnancy. This is an abnormal form of pregnancy where a egg that had lost its dna becomes fertilized by sperm (complete mole) or an egg becomes fertilized by two sperm or a sperm that has duplicated itself (partial mole). Molar pregnancies occur randomly, in about 1/1000 pregnancies, and cannot survive. They can develop into choriocarcinoma, a form of cancer.

Why do women under 20 or over 40 years of age have a higher risk of a hydatidiform mole?

Why do women under 20 or over 40 years of age have a higher risk of a hydatidiform mole?

Molar pregnancy: Being younger or older is a risk factor for a molar pregnancy. One of the causes of a molar pregnancy is dispermy, or the fertilization of the egg by two sperm. Perhaps the eggs of younger or older women are more susceptible to this happening. This is my opinion.

What further treatments are required after the removal of a hydatidiform mole?

Following HCG levels: After a woman has a D&C to remove a molar pregnancy, it is usually recommended that she go on a reliable method of birth control and avoid conceiving for a year. Serial measurements of the HCG level are done and are important to determine if the molar prenancy has been completely removed and then to make sure that there is not reocurrance, which is associated with a poorer outcome.

Had hydatidiform mole pregnancy, it was terminated bec cystic hygroma fetus, do I've chance for another normal preg? Do I need treatment?

Had hydatidiform mole pregnancy, it was terminated bec cystic hygroma fetus, do I've chance for another normal preg? Do I need treatment?

Yes: Any abnormal pregnancies such as this are due to genetic it Tatian's which can happen only one time there's no guarantee you will have another problem like this. To be sure you might want to have genetic counseling or you can check your chromosomes it's possible that you have a chromosome disease that could be inherited most likely it is a random mutation which will never happen again

Which procedure is most likely to be used for the removal of a hydatiform mole?

Hydatiform Mole: If your doctor suspects a molar pregnancy, a suction curettage (d and c) may be performed. A hysterectomy may be an option for older women who do not wish to become pregnant in the future.

Probably pregnant: It's possible to get pregnant even without penetration. Enough seminal fluid can sometimes get into the vagina and cervix to get you pregnant. So if your pregnancy test is positive, it's likely true. A hydatidiform mole is much less likely, but possible. See your doctor, and some blood HCG levels can help figure it all out.

What is the difference between a keloid and a mole?

What is the difference between a keloid and a mole?

Big difference.: Moles are benign lesions that stable over time but may grow slowly. If they suddenly change, a biopsy may be recommended. Keloids grow and be one larger over time and generally associated with trauma or injury or inflammation. The keloid in the photo has been treated whereas the other smaller pigmented lesions appear more similar to moles.

What is the difference between a severely atypical mole and melanoma?

The difference is...: That atypia in a mole (or nevus) is generally thought to represent a premalignant change but not an invasive malignancy. A melanoma is a malignant tumor that can invade surrounding tissue and metastasize (spread) to other organs and lymph nodes. The difference is premalignant vs. Malignant.

What is the difference between a punch biopsy and shave biopsy for mole removal?

Depth: The main difference is depth. In punch biopsy you try to get as much depth as possible while in a shave you try to scrape the lesion without going too deep.

How can I tell the difference between a mole and a freckle?

How can I tell the difference between a mole and a freckle?

Why do you ask?: Freckles darken and lighten depending on sun exposure and occur in groups. A lentigo is a solitary dark spot that's flat. A nevus tends to be larger than a lentigo and may be palpable. The latter two are often called "moles". A pathologist can tell the difference on biopsy. It's more important that you be able to recognize lesions suspicions for melanoma and get them off promptly.

How to tell the difference between a mole and a dysplastic nevus?

How to tell the difference between a mole and a dysplastic nevus?

Biopsy is only: Way to tell for sure. A qualified dermatologist can usually tell the difference between a benign or suspicious lesion in the majority of cases, so you should see one if your mole has changed appearance or increased in size.

What's the difference between nodular melanoma and a regular mole?

What's the difference between nodular melanoma and a regular mole?

Melanoma: Melanoma is a potentially serious form of skin cancer. A regular mole is not a skin cancer and rarely regresses into a skin cancer.

How do I find what's the difference between a mole, skin tag, and cancer?

How do I find what's the difference between a mole, skin tag, and cancer?

A biopsy: A skin tag tends to look like a grainof rice or small tag coming from the skin they are no cancerous more common in overweight persons with redundant folds of skin the neck and axilla are common places. A mole is a growth of cells on the skin normally bening but some can change and that is why you should see a dermatologist. Moles tend to be round smoothed walled and ma have hairs.

What's the difference between a regular mole and a dysplastic nevus? Both had the potential to become malignant.

What's the difference between a regular mole and a dysplastic nevus? Both had the potential to become malignant.

D. Nevi vs. Melanoma: Any skin color can have nevi, but they are harder to follow on dark skin. Nevi, pigmented lesions, can change color, itch, bleed, or have irregular borders. They are on the spectrum from dysplastic nevus to malignant melanoma. Some people have many nevi and are at higher risk of getting a melanoma, especially with family history. Sun Protective clothing is key: sunscreen doesn't block melanoma.

Can dermatologists tell the difference between a normal mole and nodular melanoma?

Yes: There is a big difference between a normal mole and melanoma. We look at the characteristics of the lesion abcde (asymmetry, borders, color, diameter, evolving) and biopsy any suspicious moles in question. The biopsy would confirm which is which.

What's difference between moles and freckles?
