Líquen aureus "algesiogênico"<A href="#nota"></A>

Abstract

A case is described of lichen aureus in a 23 year old female with a 2-year history of painful, purpuric, rust-coloured to tan, lichenous lesion on forearm. A biopsy specimen demonstrated a dense lymphohistiocytic infiltrate in the upper dermis, with extravasation of red cells. The "algesiogenic" lichen aureus is a very rare dermatosis.

Unilateral Lichen Aureus in a Child - Case Report

“…Lichen aureus is a rare pigmented purpuric eruption, distinguishable from others by having segmental distribution or isolated localized lesions, as in our patient. 3,7 Although often bilateral, the unilateral distribution as in our case, was the predominant variant in a recently published Chinese series. 5 Lichen aureus occurs most frequently in young adults with male predominance.…”

“…5 Lichen aureus occurs most frequently in young adults with male predominance. 1,3 In children, it tends to be self-limiting whereas in adults spontaneous resolution is rare, usually after years. 1,2 The etiology remains unknown, but studies suggest that it is associated with venous insufficiency, infection and/or drugs such as pseudoephedrine and glipizide.…”

“…Differential diagnosis should include other purpuric dermatoses, as well as nummular eczema, contact dermatitis, histiocytosis and traumatic purpura. 1,3 Treatment of lichen aureus is challenging but can be done with higher-potency corticosteroids, although there is little response. Moche et al, 6 and Kim et al 1 reported cases of lichen aureus with a satisfactory response to methylprednisolone aceponate 0.1%.…”

“…1,2 It is an inflammatory disease with a chronic course characterized by macules, papules or patches with a lichenoid aspect and a variable color from brown to gold or erythematous-purplish. 3,4 Usually lesions are bilateral, painless, although there are reports of unilateral, painful, zosteriform manifestations that become confluent, called agminate lichen aureus. 5 It localizes preferentially to the lower limbs, although it can also affect the arms, hands and dorso.…”
