Clinically, it is characterized by intensely pruritic, grouped papulovesicular eruptions distributed symmetrically over extensor surfaces, including the elbows, knees, buttocks, and posterior scalp Pathophysiologically, the disorder is defined by circulating IgA antibodies against transglutaminases, leading to pathognomonic granular IgA deposits in the superficial dermal papillae that recruit neutrophils and form subepidermal microabscesses
