Sudden rash on top of hands, small bumps around knuckles/fingers,

This answer was rated:

Sudden rash on top of hands, small bumps around knuckles/fingers, now spread to top of hands. Not blisters, more like real small bumbs...itches

dermdoc19 :

Hello and good evening.

Customer:

Hello there

dermdoc19 :

As someone with psoriasis who develops this around the hands, that would be one possible diagnosis. However, this sounds a bit more like dyshidrotic eczema (pompholyxz)

dermdoc19 :

We not know exactly what causes this, although most authorities feel that the little vesicles ( water bumps) that you see are due to trapped sweat.

dermdoc19 :

The best treatment for this is cold tap water ( or DomeBoro) dressings.

Customer:

Came on very quickly, tought an aleric reaction. It's not like my usual psoriasis, which I have never had on mmy hands. Should I just get some lotion from the store?

dermdoc19 :

Twice a day.

Customer:

What is DomeBoro dressings

dermdoc19 :

If this came on suddenly it is more likely due to pompholyx. We are seeing more of this problem with the hot weather and sweating.

dermdoc19 :

Dome Boro is aluminium acetate. It is over the counter.

dermdoc19 :

After the dressing apply a mid strength steroid such as Fluticasone cream or even a high potency cream such as Clobetesol cream. The best you can do over the oc**ter would be Cortizone 10.

dermdoc19 :

Oral antihistamines can be taken to relieve the itching. Beneryl 25 mg. at night and Allegra 180 mg. during the day.

dermdoc19 :

Trying to control sweating will also help, but that is easier said than done.

dermdoc19 :

Stress tends to make it worse because it increases sweating.

dermdoc19 :

Any questions or need clarifications?

Customer:

No stress or sweating, work in office and a/c at home. daughter does not think its eczema from heat, so no trapped heat. Again came on very quickly. Will rinse with cold water and get some cortizone 10

dermdoc19 :

Do the small bumps have fluid in them at all? If not this is an acute allergic contact dermatitis. Treatment recommendations would be the same.

Customer:

No fluid noticed...maybe I have been around something not typical and had an alergic reaction. Could my cat have brought something in, she gets bumps on her neck at times. Would an alergic reatction last for a few days? Came on Saturnday night, spread mostly yesterday to top of hands. Some of the small spots (very small) have scabs on them - again very small

dermdoc19 :

It sounds like a contact dermatitis. However, a photograph would help if you would be able to send one.

Customer:

Cant send a photo...but "contact dermatitis" just means an alergic reaction?

dermdoc19 :

Not necessarily an allergic reaction. There are two types an irritant contact dermatitis and an allergic contact dermatiktis.

Customer:

OK..thank you
