Must pigment regrowth be excised?

Forums General Melanoma Community Must pigment regrowth be excised?

    After early melanoma diagnosed 3 years ago, I’ve had many additional biopsies.  Most have come back as nothing, some mild atypia.  There have been a few over the years where pigment has regrown.  They were normal when biopsied before, and look the same normal again now.  Must they be excised simply because they regrew?

      I would show them to your derm and discuss.  Does your derm use a shave biopsy technique?  This type of biopsy can leave cells behind that can grow back later.  If you have this happen a lot, then talk to your derm about another biopsy technique to remove the entire lesion.

        usually deep shave/scoop

        Yes, not my favorite biopsy type for the very reason you describe.  If the biopsy happened to be melanoma, it might cut through the lesion and you lose important staging information.  Ideally, you want the entire lesion removed with a biopsy and if you are having regrowth, that means the entire lesion isn't removed.  I, personally, prefer punch biopsies but many derms don't like those as well because they require more time to do and also require stitches.  Shaves are easy for derms.  But if it is being biopsied as a possible melanoma, then I refuse to have a shave done.

        My derm said that deep shave is much better than a punch biopsy which doesn't get clean margins. he showed me this study: http://www.ncbi.nlm.nih.gov/pubmed/12637923

        "Both superficial and deep shave biopsies were more accurate than punch biopsy for melanomas less than 1 mm. Excisional biopsy was found to be the most accurate method of biopsy.

        CONCLUSIONS: Deep shave biopsy is preferable to superficial shave or punch biopsy for thin and intermediate depth (<2 mm) melanomas when an initial sample is taken for diagnosis instead of complete excision."

        HAVE YOU RECEIVED COPIES OF THE PATHOLOGY REPORTS?  Did they state that the deep shave had optained clear margins?  If so, why doess the "mole keep regrowing?  Ddddddoes the Deep Shaves you are getting cover the 2 mm depth?  Outside of the Deep Shave taking less time (!10 minutes) while the Excision often takes around an hour, I would be uncmfortble with having repeat re-growths.

        It's a matter of opinion.  My mel onc will NEVER do a shave on a suspected melanoma because it is not a FULL SKIN THICKNESS biopsy.  Deep shaves cannot guarantee full skin thickness and if they aren't thick enough, you lose staging info.  Period.  Besides, shaves hurt much more while healing and look worse when they are done.  I will never have another one for those reasons either.  Obviously, the original poster is not getting clean margins on her shaves or else she would not be having regrowth.

        There is a time and a place for all biopsy types.  If the original mole is much wider than a punch biopsy, then an excisional biopsy will be done in my case, not a deep shave.  Punches have limitations on width.  But I always want to get the depth info as it is much more important than a side margin not being totally clear.  Derms LOVE shaves because they are quick and easy and require no followups.  But ask your derm if he had melanoma and I bet he'd have an excisional biopsy on himself.

        I only remove moles that change so am not subject to a lot of biopsies – my body seems to have mellowed out over the last 22 years and I get few that change anymore.  But if it changes, I won't be having a shave.  Everyone is entitled to their opinion, but I've seen countless people here who have had shave biopsies that do NOT get the full depth.  They only know their depth is at least as deep as the scoop went.  To me, depth is THE #1 CRITERIA and shaves don't guarantee depth.  So I choose never to do a shave.  This is what is best for me.  If you and your doc think a shave is always best for your future and you know he will always go "deep enough",  then that works for you!

      Interesting question and one that I am curious about too.  I think I would tend to err on the side of caution, though I can see how this could get tedious if you have a lot of moles/growths.

      My son had a mole showing precancerous changes on his abdomen.  He had shave removal, followed by another removal of a pigmented area toward the top of the same lesion a few months later, which the derm suspected might be regrowth of the precancerous lesion but in fact returned as normal.  He now has a line of brown pigment straight across the middle of this same area.  I am planning to ask about it when he goes back in October. 

      thank you Janner and others – Before this thread, I had no idea there were so many types of mole removal and what the pros and cons of each might be.
