Dermatitis herpetiformis usually begins in the twenties, though children may sometimes be affected. It is seen in both men and women. Though the cause of the rash is unknown, dermatitis herpetiformis is frequently associated with gluten (a protein found in cereals) sensitivity in the small bowel.

Symptoms

Dermatitis herpetiformis is usually extremely itchy. The vesicles or papules usually appear on the elbows, knees, back, and buttocks. In most cases, it is highly symmetric. Symptoms of dermatitis herpetiformis tend to be sporadic.

Signs and tests

A skin biopsy and direct immunofluorescence test of the skin are performed in most cases. Your doctor may additionally recommend a biopsy of the intestines.

Treatment

Dapsone, an antibiotic, may help the majority of patients.

A strict gluten-free diet will also be recommended to help control the disease. Adherence to this diet may eliminate the need for medications and prevent later complications.
