Mystery Rash

I have had this itchy rash all over my body for months (since 03/2011) It started as smooth, itchy rash in my underarms. Saw an internest who gave me oral Predisone as well as a shot a few weeks later. This did nothing. It proceeded to move and cover me from the inner thighs to my neck. At this point it was bumpy, almost like sandpaper. ER doctor told me it was from dry skin, to take anti-histimines and use lotion. It cleared slightly before I got to a dermatologist who did a biopsy which came back as "contact dermatitis" and gave me more oral Prednisone and a steroid ointment. I switched all my detergents, went to mostly cotton clothing and bedding. It seems as though it only presents in areas covered with clothing. A few weeks later, my backside was just covered in scabs from itching the white bumpy hives that started popping up from my waist to my inner thighs. No more problem with the under arms. Went back and had another biopsy which result in the same contact derm. The doctor threw his hands up and said that I would just have to figure it out. Ended up at an allergist who did a patch test of 29 chemicals, none of which were positive so the allergist threw her hands up too!

Well, I have spent months covered in itchy bumps. I am miserable!!!!! And no one has an answer. What do I do now? Where do I turn? Any idea what this could be from? Do you know of a doctor that will figure it out? I will fly somewhere if I have to.

One thing I notice is that I'm much more aggravated when I'm in the humidity or when I sweat. I just moved to a very very humid area of the country right before this started. Also, I have recently gained about 50lbs in about 8 months due to some lifestyle changes and possible thyroid problems (and all the steroids). Could this be connected? About 30 of it was put on prior to the rash starting. I am reluctant to work out as it itches to sweat.

Please suggest my next move. Thank you!

Welcome to the Dermatology Expert Forum!

Would you, by any chance, be able to post clear pictures of your lesions at your MedHelp profile page. We will gladly look at them.

Also, we have several questions:
1. Have you checked your thyroid function (FT3, FT4, TSH, etc.)?
2. Were initial lesions tested for antimicrobials (for example to exclude underarm fungal/yeast infection?
2. What is your profession? What do you come in contact with?
3. Did anything happened in your life (health, work,etc.) prior to appearance of first lesions?
4. Do you have any other heath concerns (you mentioned gaining weight, anything else)?
4. Is there eczema in your family?
5. Is there any other skin diseases in your family?

Thank you!

Dear Lemon Doodle,

How are you? We have not heard from you after our initial comment with some questions. Please let us know if you can provide some additional information. If not, try to check your hormonal status, make sure you are not getting in contact with any unrecognized allergens (most basic patch testing series will not contain such allergens).

Among other skin diseases, allergic contact dermatitis,  atopic dermatitis and atypical pityriasis rubra pillaris should be excluded.

Wishing you Optimal Health,
Dr. Jasmina Jankicevic
