Abstract
Two patients with quinidine photosensitivity had an eczematous dermatitis in a photosensitivity distribution on the face, neck, hands and forearms. Histologically, both patients showed a bandlike dermal lymphohistiocytic infiltrate with overlying vacuolar changes and necrosis in keratinocytes at the dermoepidermal junction. On phototesting, both patients showed marked sensitivity to UVA radiation. Sensitivity to IVB was difficult to assess.
