I have been doing a vast amount of research as I have been suffering from pompholyx or dyshydriotic eczema for the last 7 years.
Steroid creams have been of no help to me. This made me wonder if my rash was eczema at all. I started looking at fungal rashes/infections and after talking to a doctor, I obtained an topical antifungal cream and my rash is nearly gone, after 7 YEARS!!!
Medical literature talks about a dermatophytid reaction or the "Id" reaction. If a person has a tinea
or fungal infection, usually found on the feet or in the nail beds, then they are more likely to have a skin reaction on their hands than if they had atopic dermatitis or a nickel allergy according to one study. Skin conditions may be an allergic reaction to cutaneous fungal infections elsewhere on the body usually on the feet. (I am sure that most of us have had athlete's foot at one time or another) What is interesting is that the fungal infection may be ASYMPTOMATIC and still produce outbreaks on the body. Depending on the location fungal infections may be differentially diagnosed as
Vesicular eruptions on the hands and feet
Erythema annulare centrifugum
Steroid creams will not help a fungal infection, in fact they might make it worse! If you have resistant skin conditions it might be worth your while to have a biopsy of your rash, or examine your feet and toes for fungal infections.
