Thank you Dr. Kaur for looking at this, and, thanks for your advice. I have no other areas affected (no web spaces in fingers, waist, or anywhere). Just these areas that the photos show. I'll try to relax until I see the dermatologist.
Hello,
Thanks for posting your query.
I can understand your concern for these symptoms. I have checked the photographs and from the photographs of hand and fingers it looks like dyshidrotic eczema or pompholyx but for the ankle photograph it can be atopic dermatitis also apart from the possibility of psoriasis which your doctor has suggested.
It is true that scabies affects the fingers and webspaces but it is highly contagious and causes an intense itching sensation caused by an allergic response. Since your wife is not having any such symptoms and there is no intense itching as symptom, it is less likely to be due to scabies.
The first stage of pompholyx shows tiny blisters (vesicles) deep in the skin of the palms, fingers, instep or toes. The blisters are often itchy or have a burning feeling. The condition may be mild with only a little peeling. Then the chronic stage begins which consist of peeling, cracking, or crusting. The exact cause is not known and excessive sweating can be one of the reasons. But some triggers like allergic reaction to soaps, detergents, foods, latex, nickel etc may trigger the symptoms.
Apply some calamine lotion on the affected area and keep the area well moisturized. Use only thin applications of moisturizer ointments as excessive amounts of ointment may restrict breathing of the skin and aggravate the condition. You are using the topical steroid cream but it should be used for time period mentioned by your doctor.
Atopic dermatitis is an inflammatory, relapsing, non-contagious and itchy skin disorder which is characterized by dry and scaly skin which may weep, crack, swell, and crust over. Psoriasis is a long-term (chronic) skin problem that causes skin cells to grow too quickly, resulting in thick, white, silvery, or red patches of skin which are non itchy and non contagious.
To confirm the diagnosis, I suggest you to get it examined from a dermatologist and get a biopsy skin done. Treatment is diagnosis specific and depends on the confirmation of diagnosis.
Hope that this information helps and hope that you get better soon.
Wishing you good health.
