What is Dermatitis Herpetiformis?
Dermatitis Herpetiformis (DH) is a skin condition characterized by intensely itchy bumps and blisters. It is often mistaken for other conditions like bug bites, scabies, or neurotic excoriations.
Who is at risk?
People with a genetic predisposition to gluten sensitivity and those with skin phototypes I-III are most at risk. It is less common in people with skin phototypes IV-VI and Asians. Men are twice as likely to develop DH as women, and it typically appears in adulthood.
What are the signs and symptoms?
The initial symptoms are often minor, with a few itchy bumps or blisters. However, it eventually progresses to widespread itching and burning, with the appearance of papules and vesicles. The blisters are often broken open due to scratching. Other symptoms can include oral dryness, mouth ulcers, and tooth enamel defects.
