question: Hello and good afternoon. Just recently I ve noticed a small sized white spot on the shaft of my penis. It s only in one spot - mid shaft, and is neither hard or painful. My concern is that it is becoming more pronounced in its discoloration. My nurtural skin tone is brown and I noticed the circle a few months ago. Today it just seems whiter and maybe a bit larger, but still rather small. Fungus or Vitiligo?
