Abstract: | Localized persistent pigmented macules and plaques due to a chronic form of pigmented purpuric dermatitis are described in forty-two patients. The designation 'lichen aureus' for this eruption can be justified because of the striking yellowish or bronze-like colour assumed by many of the lesions. The lower legs were the commonest sites but other body regions can be affected also. Histologically lichen aureus differs from other pigmented purpuric dermatoses in the density of the lichenoid tissue reaction and the marked accumulation of pigment-containing macrophages. Recently developed endothelial cell markers have been studied in selected cases. |
