Dermatitis herpetiformis is a chronic skin condition prompted by gluten intolerance; it is also called a celiac or gluten rash. Not all people with celiac disease will develop the rash. It appears symmetrically on the body, often on the elbows, legs, or knees. The rash more commonly affects men than women and presents in about 24% of people with celiac disease. It often comes on suddenly, causing extreme itching and blistered skin. Diet can help prevent the flare-ups.
