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

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

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

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

If I have dysplastic nevi syndrome and my brother in law had malignant melanoma do my children have any  more risk of getting either one?

It's no reason to forego parenthood; just you be sure that you and all your kids keep a really close eye on your skin. Glad you're proactive. ...Read more
