*CORRECTION* My last post should say "minocycline", NOT "monocycline".
You poor thing. I have GA localized on my hands and was looking for answers to the same question you asked. A few minutes ago, I just read on Wikipedia, "New research out of India suggests that the combination of rifampin (600 mgs), ofloxacin (400 mgs), and monocycline hydrochloride (100 mgs) once monthly, or ROM therapy, produces promising results."
I'm not a doctor and you never know how accurate Wikipedia is, but that may well be worth researching and talking with an experienced dermatologist about. I know I will be.

While now they use biologicals in GA which have side effects, herewith giving you a relatively safe therapy tried years back.
Do consult your physician before any treatment.ok?
Best wishes.
As I told you I would have thought of T.corporis with only the photo minus history.
While agreeing with the earlier diagnosis,generally granuloma annulare lesions are indolent and slow in evolution.
My thought here was, can not a patient with GA have tinea growing now? If there are no new lesions and it is the only old ones that are growing I would say it is only GA.
It is prudent therefore to have another look at it.
My good wishes.
It is not ringworm, my dermatologists have tested for that. I have had both a punch biopsy and an incisional biopsy done on different areas of my body that are affected and both confirmed granuloma annulare.
I had a re look again and looking at the central clearance and peripheral extending borders, gives a fairly clear diagnosis Tinea corporis.
Cheers!
If I were looking at the photographs without history, my clinical impression would be Tinea corporis (Tinea incognito). I wonder whether this is at all related to your original diagnosis. I would do a scraping for fungus and then proceed.
Regards and best wishes.
