Does Hashimoto's thyroiditis cause skin rash on neck?

default
Posted on Fri, 13 May 2016
Question: I have Hashimotos. My thyroid was removed last year in January after which I found out I had thyroid cancer. I was treated with radioactive iodine in March. In August, I developed a rash all around the incision spot, over the past several months it has spread around my neck and to my earlobes. I have seen my PCP, my endocrinologist and my allergy doctor. None can seem to figure it out. Is is possible the Hashimotos is still attacking me? Could I have developed another auto immune problem?

Brief Answer:
Unlikely

Detailed Answer:
Sorry to note your skin problem.

Hashimoto's thyroiditis does not cause a skin rash.

It is likely a different skin problem for which a dermatologist needs to be consulted. Treatment will be directed at the cause accordingly.

When I see someone like you in my practice, I typically order the following blood tests in addition to a detailed physical examination:

CBC (Complete Blood Count, also known as Hemogram; includes Hemoglobin, WBC and Platelet counts)
Electrolytes (Sodium and Potassium in particular)
HbA1c (Glycosylated Hemoglobin = your 3 month glucose average)
Liver function tests (SGOT , SGPT, Albumin, Bilirubin, Alkaline Phosphatase)
Kidney function tests (BUN, Creatinine)
TSH
Free T4
Serum Quantitative thyroglobulin
Anti Thyroglobulin antibodies
25 hydroxy Vitamin D
Ultrasound of the neck

Could it be caused by stress if it's tied to an autoimmune issue? I also have terrible brain fog and fatigue and I don't sleep well. Though, to be fair, I have had insomnia since birth. I also have frequent diarrhea. I have gained about 40pounds this past year -partly thyroid, mostly bad habits, I am sure. I am trying to get back on track to health, but quite frustrated.

Detailed Answer:
Stress induced skin lesions are possible/ Again, it is the expert opinion of a skin specialist that is required with the opportunity to examine it too.

To be sure that your other symptoms are not due to thyroid issues, just make sure your TSH and Free T4 are in the target range
