Overview
Dermatitis herpetiformis is an extremely itchy rash which appears as bumps and blisters. The rash is chronic, which means it continues over a long period of time.
What are the symptoms of dermatitis herpetiformis?
Dermatitis herpetiformis is usually extremely itchy. The bumps or blisters usually appear on the elbows, knees, back, and buttocks. In most cases, the rash is the same size and shape on both sides. Symptoms of dermatitis herpetiformis tend to come and go.
What causes dermatitis herpetiformis?
The cause is unknown. However, dermatitis herpetiformis is frequently linked to gluten sensitivity (celiac sprue disease) in the small bowel.
Who is at highest risk?
Dermatitis herpetiformis occurs in both men and women, usually of age 20 years and older. Although children may be sometimes affected.
Diagnosis
The initial diagnosis can be made clinically by the history and examination. For confirmation a skin biopsy is done along with blood tests to find the cause of the rash which can be celiac disease.
When to seek urgent medical care?
Call your health care provider if you have a rash that continues despite home treatment.
Treatment options
Dapsone, an antibiotic, may help most patients.
A strict gluten-free diet will also be recommended to help control the disease. Sticking to this diet may remove the need for medications and prevent later complications.
