I have this thing on my left leg that is usually pink, sometimes shiny, sometimes bleeds/oozes for no reason, sometimes itches, sometimes raised and sometimes flat. I went to the dermatologist who says it's "scar tissue from a mosquito bite" and prescribed some triamcinolone. The problem with that is I remember it back in January, long after mosquito season ends in Iowa. I explained this to him but he's convinced it's scar tissue. It's been a few weeks and I've been using the TAC, but it's not helping. While I was at the fair, I stopped by the skin cancer screening booth and saw a derm. who was quite concerned about the area and told me I should really get it biopsied. My regular derm. is really not concerned. Who do I believe? Should I get a third opinion?
