That is an exact description of the strange sores that I always had, especially in the summer. Mine also got sort of scaly and some would get really bad. It really surprised the PCP that I had about 10 years ago when she sent one to a lab and found abnormal T-cells. It really wasn't associated with lupus until now that I've been diagnosed with AI issues. I've been on Plaquenil since March and MTX since June, and this summer, for the first time in years, I didn't have a single sore!
