Hello,
These blotches can be due to nummular dermatitis, granuloma annulare or lichen planus. Granuloma annulare is a chronic disease consisting of rings arranged in a circle. It presents as small, firm bumps (papules) over the backs of the forearms, hands, or feet and other body parts. Treatment is necessary for cosmetic purposes and consists of steroids and intralesional steroid injections.
To confirm the diagnosis get a biopsy skin done from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Hi,
Am a member like you, so cannot offer medical advice, but I'd ask your doctor .. maybe some type of cortisone may help and/or be able to diagnose this for you. But you cannot use topical cortisone cream over such a large area w/o consulting your doctor.
Could it be some type of allergic contact dermatitis?
