What are the signs and symptoms of dermatitis herpetiformis?

If you have dermatitis herpetiformis, you may have one or more of three problems: skin problems, problems in your mouth and gastrointestinal problems.

• Skin problems: Skin problems are the most common and the key sign of dermatitis herpetiformis. Problems include red bumps (lesions) and itchy, sometimes burning blisters. Skin problems are found on your elbows, buttocks, knees and scalp.
• Oral problems: Dermatitis herpetiformis can cause tooth enamel problems. You may see pitting, discoloration, horizontal grooves and (rarely) canker sores.
• Gastrointestinal problems: Celiac disease inflames and damages the small intestine. Almost all people with dermatitis herpetiformis are sensitive to gluten and have celiac disease but are less likely to have gastrointestinal issues. But, patients who do have symptoms may have bloating, cramping, diarrhea, constipation and pain.
