Harald Kittler on the myth of Dysplastic naevi

Professor Kittler explains why we now have good evidence, not least from digital monitoring, that ‘dysplastic’ naevi are NOT precursors to melanoma. They are just slightly funny looking moles. His team have digitally monitored some 30,000 such moles and none has turned into a melanoma. A better term would be ‘atypical’. Listen to him for the full picture.

    Does that include observation of all degrees of atypia? Mild, moderate and severe?

      I can only suggesst listening to Prof Kittler, he knows more than I do. Basically, we are cutting out a lot of ‘atypical/dysplastic’ naevi which are actually harmless and would never cause the patient any harm. dysplastic naevi have not been established to be precursors of melanoma. However, people with large numbers of atypical naevi do have increased risk, so whould ideally be digitally monitored or at least photpgraph their own skin. If they get a melanoma, and some will, it will rarely come from one of teir atypical moiles, more likely from a bland naevus or out of clear skin. Hope that helps.

        Over here in the US, most derms will excise moderate and severe atypia.

        Some still shave off mild atypical.

        My personal experience going on right now is I’m about to have a WLE on a nevus that came back severely atypical. It’s a nevus that I chemically burned and ruptured 17 months ago and decided to have it checked out and to our surprise it came back with severe dysplasia. We are thinking that the trauma may have played a part but leaving something sever like that on me isn’t something I want to do.

        I watched his presentation so basically a melanoma will always be a melanoma from the moment it appears on the skin and a dysplasia nevus is not a biological precursor to melanoma, regardless of the degree of atypia. I know some dermopathologists and dermatologists have some issues sometimes distinguishing melanomas in situ and severely dysplasia so if they can’t confidently call is severely dysplasic, they use the phrases “severe atypia evolving into melanoma in situ” or “cannot exclude melanoma”.

    Does that imply to just certain degrees of atypia? Or all, mild, moderate and severe
