Goldyfm, hi. I've heard of the granuloma annulare "aint easy" just mentioned.
I had years of ringlike nonscarring lesions, so my local dermies considered everything "ringlike". They all blew it, but at least they gave me pics, photocopies from medical texts, etc.
Anyway, my rash was ultimately Dx'ed by teaching hospital specialists as the annular (ringlike) form of SCLE = subacute cutaneous lupus erythematosus. The autoantibody found most of the time with this rash is "anti-Ro". This rash favors upper arms & torso (chest &/or back). Sunblock & avoidance is a must for me, not to mention Plaquenil, which has helped me a lot with various symptoms, not just skin.
In contrast, I *think* granuloma annular favors hands, elbows, knees & feet.
But saying a rash "favors" a body area probably means there are exceptions to the general rule, would be my guess...
Ummmm... I don't think I'd use an emery board on a rash, for fear of opening skin to infection...? For what this is worth (quite possibly not so much
), with best wishes, Vee
