Segmental lichen aureus: an uncommon presentation

Abstract

Pigmented purpuric dermatoses are chronic vascular inflammatory conditions characterized by the presence of pigmented macules. Among its different presentations, lichen aureus is distinguished by the lichenoid conformation of its plaques and the predilection for lower limb involvement. Its segmented form is rare and difficult to control, especially in cases of symptomatic lesions. We report a rare case of segmental lichen aureus with six years of evolution associated with light itching. We also discuss the main therapeutic approaches to control the disease.

Treatment of segmental lichen aureus in the pediatric age with a 755 nm alexandrite picosecond laser. A new therapeutic approach for pigmented purpuric dermatosis

“…Although LA is usually confined to a small area, several reports of segmental LA exist in the scientific literature [1,4,5], including pediatric cases [6,7]. Lichen aureus histologic analysis is characterized by a lichenoid lymphocytic infiltrate with a grenz zone and extravasated erythrocytes.…”

Behandlung eines segmentalen Lichen aureus bei einem Kind mit 755 nm‐Alexandrit‐Pikosekunden‐Laser

“…Obwohl LA gewöhnlich auf ein kleines Gebiet beschränkt ist, gibt es mehrere Berichte über segmentalen LA [1,4,5], darunter auch pädiatrische Fälle [6,7]. Histologisch ist der Lichen aureus durch ein lichenoides lymphozytäres Infiltrat mit einer Grenzzone und Erythrozyten‐Extravasaten gekennzeichnet.…”
