If you have a dysplastic mole removed will it return?

If you have a dysplastic mole removed will it return?

Dysplastic moles: "the moles look unusual, clinically, and they have some features in common with melanoma, so they may get biopsied. When they get biopsied, they may have some cytologic atypia, which is reported as mildly dysplastic, moderately dysplastic or severely dysplastic. This report may cause the dermatologist to re-excise the lesion to make sure that it is all gone. ...Read more

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

If a mole was removed & was normal but reoccurs years later. Is it logical that it would show as dysplastic if it wasn't completely removed 1st time?

If a mole was removed & was normal but reoccurs years later. Is it logical that it would show as dysplastic if it wasn't completely removed 1st time?

Most likely no: Depending on how deep the mold removal was and how deep the pigmented cells were, the mole can come back, but if the original biopsy showed benign, then most likely you do not have to worry abou it, but see a dermatologist to be on the safe side. ...Read more

Mole removed. Over time it slowly grew back. Removed again and now shows dysplastic? Can original removal cause a false positive an subsequent biopsy?

Mole removed. Over time it slowly grew back. Removed again and now shows dysplastic? Can original removal cause a false positive an subsequent biopsy?

False positive: Although previous surgery and/or trauma to an area can create difficult-to-interpret pathologic changes, that does not mean that dysplasia is not present. If a mole is dysplastic on pathology, then additional excision is required (assuming the biopsy had a close margin). Return to your dermatologist for a full discussion about this. ...Read more

If a mole is removed that is dysplastic on pathology should wider margins be taken out as a precaution even if original biopsy visually got it all?

If a mole is removed that is dysplastic on pathology should wider margins be taken out as a precaution even if original biopsy visually got it all?

Atypia.: Dysplastic lesions should initially be removed with a 2-3 mm margin. If this was done and the pathologic margins were clean then no further excision is recommended. If the pathologic margins are positive (sounds like they were not) then re-excision depends upon the degree of atypic and experience of the provider. ...Read more

3 mm wide mole removed. Pathology dysplastic but no mention if margins were clear. Why wouldn't pathologist indicate clear or not? Re-biopsy required?

Margins on mole: Margins are typically reported on most moles. However, if the initial excision was a shave or a close biopsy, where primary goal was to see if it was dysplastic and limit the size of the defect, then margins may not matter on the report. Best to consult with your dermatologist since an additional excision may be required. ...Read more

Why aren't all dysplastic moles removed from people as a precaution?

Dysplastic moles: The only way to know if a mole is truly dysplastic is to biopsy it and look at the cells under the microscope. At that point, the dermatopathologist can determine the level of dysplasticity. Once that information is acquired, the treating physician will know whether or not complete excision is warranted. ...Read more

Dermatologist told me dysplastic moles do not turn cancerous and only high dysplasia ones should be removed in case pathologist undiagnosed? Is true?

Dermatologist told me dysplastic moles do not turn cancerous and only high dysplasia ones should be removed in case pathologist undiagnosed? Is true?

Basically: If your dermatologist is confident that a particular nevus is dysplastic and not melanoma, leave it on. Keep an eye on your skin. Folks with dysplastic nevi are at greater risk for melanomas. Stay vigilant and you'll be okay. ...Read more

Dermatologist office called. Tiny mole they removed was mildly dysplatic. He wants to do a larger incision 'just to be safe because of an area of damage skin'. What does this remark mean?

Mole: Atypical, formerly termed dysplastic moles are "graded" mild, moderate, or severely atypical. The biopsy is read by a pathologist and it may be determined if the mole was completely removed or not. At times, the dermatologist may use clinical judgement to remove more tissue if the results are ambiguous. Talk to your dermatologist regarding all options ...Read more

I think I might have dysplastic mole syndrome. Worried?

Take charge: Either you do or you don't. In either case, if you keep a close eye on your skin (and somebody special and/or your physician keeps on eye where you can't see by yourself), your changes of dying of malignant melanoma are near zero. You can't just sit and fret any more than if you thought your house was on fire. Now's the time to get with a physician who's competent on managing this. ...Read more

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. ...Read more

Does this mole look like a dysplastic nevi, or something concerning that should be looked at by a dermatologist? Thank you!

Yes: Any mole that looks different from other moles on your face or body is suspicious. Irregular borders, irregular pigmentation, recent change in appearance, rapid growth, are all warning signs of a potential problem. Consultation with a dermatologist is indicated for any of the above signs. ...Read more

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. ...Read more

I used a needle and picked at a black mole, I think it's dysplastic nevi. Will this lead to skin cancer?

I used a needle and picked at a black mole, I think it's dysplastic nevi. Will this lead to skin cancer?

No: It is either cancer or not. Picking at it can make it inflamed, but not change it into cancer. Chronic irritation is not good, but a one time event is fine. If you think it's dysplastic then see a dermatologist to have it removed. Dysplastic nevi can become malignant over time. ...Read more

I get yearly skin screenings and will continue to do so. My question is about a previous excised mole. It was a moderate-severe atypical dysplastic nevus. I know having atypical moles can be a sign of increased chance of melanoma. I've also read that ma

Low risk: As long as the atypical nevus was excised with negative margins (normal skin at all edges), then you should be fine. Lower your risk of developing a new problem somewhere else by avoiding excessive sun exposure, or by using frequent applications of sunscreen if you must be out in the sun. ...Read more

Can a person have pain on the bottom of the foot if you have a "funny looking" mole on the side. Dermatologist said it's a dysplastic nevi.

See a dermatologist: If you are truly concerned about it and you feel that it is actually the dysplastic nevi causing the pain and nothing else then I recommend seeing a dermatologist so they can discuss treatment options. In the mean time make sure that you wear plenty of sunscreen and keep the dysplastic nevi out of the sun. ...Read more

With "recurrent Nevus phenomenon" could a previously benign mole now appear dysplastic if pathologist not aware of previous biopsy or laser ablation?

With "recurrent Nevus phenomenon" could a previously benign mole now appear dysplastic if pathologist not aware of previous biopsy or laser ablation?

Yes. Hx is important: When a benign nevus grows back after biopsy, and is re-biopsied or excised, it may now show features that closely mimic a dysplastic nevus or even melanoma under the microscope. This melanoma-like pattern is called "recurrent nevus phenomenon." A pathologist might accidentally misdiagnose a benign, recurrent nevus as a DN or melanoma, if they don't know (or suspect) it was previously treated. ...Read more

Do all dysplastic moles eventually turn into melanoma?

Do all dysplastic moles eventually turn into melanoma?

No, they do not: Dysplastic nevi are considered a marker for melanoma risk but not a precursor lesion. Most melanomas arise on normal skin, not in a mole. Sometimes moles do develop melanoma & they start changing, one of the things we look for when suspecting melanoma. We look for abcde asymmetry, border irregularity, color irregularity & change or evolution in melanoma. Any changing mole needs to be seen by derm. ...Read more

Only way: They have high incidence of malignency (melanoma) you may have dysplastic nevi syndrom, most likely some one in the familty have it al;so. Melanoma is curable if excised early, abcd s of detection are asymerty, borders, color, diameter, and evalution by your dermatologist (or surgeon). ...Read more

Dysplastic nevus, or atypical moles, and they are benign lesions that resemble early melanoma, and about 1 in 10 million americans willmelanoma, what to do?

Dysplastic nevus, or atypical moles, and they are benign lesions that resemble early melanoma, and about 1 in 10 million americans willmelanoma, what to do?

Watch carefully: Dysplastic nevi are potentially serious in that they can convert to infiltrating melanoma. In children with spitz nevus, they look malignant but never convert. In patients with neurofibromatosis there is a high incidence of dysplastic nevi and since many are present they are watched for changes in shape, darkening in color or redness around the lesion suggesting that they are converting. ...Read more

Derm noted 3 moles on back. All 3mm or under. One shade and pretty much round or oval. He said slightly dysplastic so best to remove now. What does that mean. .. Are they likely to be melanoma?

Never know: No one know for sure until a biopsy comes back, which provides definitive diagnosis. Melanoma often tends to be very dark. It sounds like you may have some "basic" lesions that just need to be evaluated further as recommended by your derm. Best wishes. ...Read more

I have dysplastic nevi syndrome, I had 2 very similar moles shave biopsied. How is it that one came back as a sun spot, one needed reexcision was mod?

Microscopic exam: Is different. A sun spot or solar lentigo shows the basal layer of skin cells having increased amount of pigment within them. A nevus is a proliferation of melanocytes (the cells that make pigment). Most dermatologists re-excise for moderate dysplasia or above to be sure not to miss any cells that could transform into melanoma (if they believe in the dysplastic nevus/melanoma sequence). ...Read more

Is it removing moles with tea tree oil possible? Regardles to some clinical trials I cannnot see how it can remove some in sito dysplastic nevus?

Wouldn't count on it: No matter what you read either on the internet or in a journal about tea tree oil, I definitely would not rely on it to treat any type of dysplastic nevus. Even a lesion in situ! It is always best to excise (have them surgically removed) and send to the pathologist, so you can have proof that the entire lesion is out. ...Read more

I had a mole removed from my abs and margins were cleared. It then formed a keloid. Am I good, or do I have to return? What should I look out for?

Is it bothersome?: Keloids are enlarged scars that are larger than the original wound. They form for unknown reasons and are generally harmless but can become itchy or uncomfortable. If your keloid is bothersome for you, then there a variety of treatment options that are available to you. If it does not bother you, then you can leave it and not worry about it. ...Read more

Dysplastic nevi: Generally I don't do shave biopsies of suspected dysplastic nevi. However if a deep saucerization was done it might be all out. It depends if the doctor thinks that the lesion was removed or not. If just the top of the lesion was removed, it should be re excised. ...Read more
