Re: Atypical but still melanoma in situ?

The pathology isn't exceptionally clear. Hopefully your derm can be more solid with an answer, but from what was put into th report, it seems as though even the pathologist wasn't absolutely certain as to how to define it. An aggressive thinking path might have posted "in situ", whereas another might see it more as "severely atypical". Either way, you needed those clear margins. Maybe think of it as a severly atypical nevus with a really bad attitude… like a rebellious 1950's teen in a leather jacket. 😉 LOL! That mole was one bad decision away from being labeled a criminal. ha! To your mohs surgeon's credit, listing it in your medical records as the "worse" of the two potential diagnosis, is probably more helpful, as this will keep docs more alert and on their toes due to your "prior melanoma diagnosis". It also helps justify any potential future excisions to your insurance billing.
