Quinidine photosensitivity.
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 UV-A radiation. Sensitivity to UV-B was difficult to assess.
