Lichen aureus (also called "lichen purpuricus") is an uncommon subtype of pigmented purpuric dermatosis. Clinically characterized by rust macules, papules or plaques, it is a chronic disease which more often affects young adults and is localized mainly on the lower extremities. The diagnosis is made on the basis of clinical and histopathological features. Dermoscopy findings are useful to confirm clinical diagnosis.<br>O l&#237;quen aureus (tamb&#233;m denominado "liquen purpuricus") &#233; um subtipo pouco comum entre as dermatoses purp&#250;ricas pigmentadas.
