I have developed a strange outbreak of ~1"-2" odd shaped brown blotches in various spots. Legs (largest is ~3" blotch behind my left knee), ribs, hips, bottom of arms - primarily in the softer, paler areas (maybe sun will help this summer). No itch, scale, sensation - just a slight redish-brown discoloration. I'll point it out to my artist, but it is nowhere near my next tattoo (or any of my existing tattoos). Wife and I thought it might be ringworm (not a worm, but a fungus) or some other systemic fungal infection, but it doesn't respond to any anti-fungal treatment, and seems to become a permanent faint-brown spot. Now, at 62 and having worked with various chemicals, carcinogens, and radioactive elements for the majority of my life, it could be most anything.
