1. Have been bothered by itchy mole like patch on mid-back, light brown, dry, scaly, rough, slightly tender, stings when itched. About the size of pencil eraser, appears to have red border on about 1/3 of edge. Had similar patch about 3 years ago about six inches below this one. Didn't realize what I was scratching at the time. Was irritated and I created a rather large, very thick scab which I accidentally scratched off, was surprised at the hole left behind, but it healed and now have very slight scar. What are your thoughts?
2. Some time ago, noticed a small lump/bump under skin on mid trunk, there was no mark on skin. Over time the skin began to change and the lump is now slightly raised. The bump is hard/solid and the skin is smooth, and a light reddish/brown.
