Dermatitis herpetiforme
Related Conditions: Dermatitis Herpetiformis
Dermatitis herpetiformis (DH) is a severe, chronic skin rash associated with celiac disease.
The symptoms of dermatitis herpetiformis are extremely itchy and blistering skin. Sometimes referred to as gluten rash or celiac rash, DH is a chronic condition that is considered to be the skin form of celiac disease. Not all people with celiac disease develop DH, but most people with DH have celiac disease.
The rash usually occurs on the elbows, knees, and buttocks and it is typically symmetrical, meaning it appears on both sides of the body. When this gluten-related rash goes away, which it often does spontaneously, it may leave brown or pale marks on the skin where pigmentation is lost.

DH is commonly mistaken for other conditions such as:
- Eczema
- Acne
- Herpes
In the past, DH was also known as Duhring disease, Duhring-Brocq disease or Brocq-Duhring disease.
Who Gets Dermatitis Herpetiformis?
- Dermatitis herpetiformis affects more men than women
- Dermatitis herpetiformis generally starts in adulthood, particularly in those in their 30s and 40s
- It’s uncommon in children, but it can occur
- About 10-15% of individuals with celiac disease experience DH
Only about 20 percent of people with DH have intestinal symptoms of celiac disease, however, biopsies show that 80 percent have some degree of damage to the small intestine, especially if a high gluten diet is maintained.
Dermatitis Herpetiformis and Celiac Disease
DH is a skin manifestation of celiac disease and is part of the abnormal immune response to gluten. For those with celiac disease and DH, eating gluten triggers an autoimmune response which causes DH blisters to form. This rash is connected to celiac disease, not non-celiac gluten sensitivity (‘gluten sensitivity’).
Dermatitis Herpetiformis Symptoms and Testing
Dermatitis herpetiformis symptoms include:
- Extremely itchy skin
- Blisters
- Lesions
It can appear anywhere on the body but most frequently appears on the elbows, knees, buttocks, lower back and scalp. Doctors diagnose dermatitis herpetiformis by performing a biopsy on the cells under the top layer of skin.

Dermatitis Herpetiformis Treatment
Dermatitis herpetiformis treatment consists of a lifelong gluten-free diet, just like celiac disease. It may take approximately six months to notice some improvement in the skin condition, and up to two years or more to achieve total control through a gluten-free diet alone. Additionally, rash symptoms can be controlled with dapsone, an antibacterial medication.
