Anyone have experience with spitz nevi moles?

Spitz nevi: Some doctors are more aggressive and recommend complete excision with clear margins of all spitz nevi, unequivocal or not, because spitz nevi have histological overlap with malignant melanoma and recurrent lesions may present with pseudomelanomatous changes, which makes differentiation more difficult later. Personally I surgically excise all spitz nevi. ...Read more

Could you know if becker's nevi can turn malignant, and is there any way to get it removed?

Could you know if becker's nevi can turn malignant, and is there any way to get it removed?

Low risk: The skin on a Becker's has only a slightly greater chance than other skin of developing melanoma, and as far as I know no increase for other cancers. Removal with laser isn't going to be perfect.

There is no one feature of dysplasia, it is a combination of findings. Young patients can have very atypical looking nevi that are completely benign. Requires experience; send to a Dermatopathologist if there is doubt. ...Read more

My dermatologist removed a clarks nevi (?) from my chest. She left a border. Should that be removed now, or should I wait 2 see if there are changes?

Resect and screen: I would remove the whole lesion with clear margins to be safe as there was something concerning about it which warranted the resection in the first place. It is possible that another area of the lesion has cells which have the potential to develop into a tumor. If you have many moles it is important that you also make sure and follow up regularly with a dermatologist for screening. ...Read more

Relax: Many healthy people have a few spiders. I've had one on my thumb pad since I was a kid. Life's difficult enough without reading all about nonspecific stuff and getting worried. Be thankful for good health. Folks who naturally tend to worry often do remarkably well when they start up an intense fitness program. Sound like a plan? Best wishes. ...Read more
