Hi, I just discovered this group, and thought I'd join to answer your question, altho now probably too late for your appt. I had a similar situation, where, by the time I went for the biopsy for a lesion on my leg, it was too late, it had pretty much healed. Then I wished I hadn't gone because they wanted to do the biopsy anyway and of course nothing showed up. I had gotten diagnosed just months ago then (it was in 2012), so was quite concerned. I didn't have any lesions again until recently (I've been lucky, I see from the reports of this group), but recently had some spots pop up on my arm. Was curious if I should get them treated or not, since the lesions are 'self-healing' they say. I had remembered the hemotologist telling me that, but not the leg lesion episode, which you reminded me of, so thanks for that! He's very good, btw, for those who might be in NYC. Dr. Bruce Raphael at NYU Langone center. He's curious, thoughtful, knowledgeable.
