Dermatitis Herpetiformis

Dermatitis herpetiformis (DH) clinically presents with excoriated papules, often prominently involving the elbows, knees, and buttocks. Intact vesicles rarely are seen due to intense pruritus and consequent scratching. A superficial dermal neutrophilic infiltrate prominently involving the dermal papillae typically is noted on histopathology. Subepidermal bullae may be observed.
