Blanching doesn’t mean anything. Check for changes in growth and itch.. I’m 31 I had a similar lesion that blanched looked like a pimple. Turned out it was nodular melanoma amelan (red / skin color). Super rare I’m 3b been on Opdvo for 6 months. All I can say is biopsy it.. everyone told me spider bite this that.. to be honest chances are super slim it is melanoma but you know nothing until you biopsy.. my doctor didn’t think it was anything I made them biopsy it
