Lichen aureus (LA) and Majocchi’s disease (MD) are two uncommon subtypes of pigmented purpuric dermatosis (capillaritis) which predominantly affect children/adolescents or young adults. LA is typically characterized by asymptomatic to mildly pruritic, small, golden, copper- or rust-colored, lichenoid papules. MD presents with a variable number of asymptomatic or slightly pruritic, annular, linear, serpiginous or arciform, erythematous patches. LA and MD display similar dermatoscopic findings, viz., irregular or roundish, nonblanchable, purpuric, reddish dots, globules, and/or patches over a red-brownish or red-coppery background, which is usually diffuse/more prominent in LA and more focal/subtle in MD. Additionally, some telangiectatic vessels may also be seen in MD, while LA may show gray spots, globules, and a network of brownish to gray interconnected lines as well.

摘要

Lichen aureus (LA) and Majocchi’s disease (MD) are two uncommon subtypes of pigmented purpuric dermatosis (capillaritis) which predominantly affect children/adolescents or young adults. LA is typically characterized by asymptomatic to mildly pruritic, small, golden, copper- or rust-colored, lichenoid papules. MD presents with a variable number of asymptomatic or slightly pruritic, annular, linear, serpiginous or arciform, erythematous patches. LA and MD display similar dermatoscopic findings, viz., irregular or roundish, nonblanchable, purpuric, reddish dots, globules, and/or patches over a red-brownish or red-coppery background, which is usually diffuse/more prominent in LA and more focal/subtle in MD. Additionally, some telangiectatic vessels may also be seen in MD, while LA may show gray spots, globules, and a network of brownish to gray interconnected lines as well.
