Abstract

Solitary purpuric plaque: clinical and dermoscopic evolution of lichen aureus

Highlights

  • Lichen aureus (LA) is a rare variant of persistent pigmented purpuric dermatitis (PPPD), and is characterized by the appearance of a solitary goldenyellow, lichenoid macule [1,2]

  • We report a clinical and demoscopic evolutionary aspect of lichen aureus in our patient

  • Three months after the purplish erythematous appearance is replaced by a coppery brown color, the dermoscopy revealed a copper-red pigmentation background, more red blood cells than white streaks (Fig. 3)

Summary

Introduction

Lichen aureus (LA) is a rare variant of persistent pigmented purpuric dermatitis (PPPD), and is characterized by the appearance of a solitary goldenyellow, lichenoid macule [1,2]. We report a clinical and demoscopic evolutionary aspect of lichen aureus in our patient. A 53-year-old woman with a history of diabetes who had been on insulin for 10 years, consulted for the management of asymptomatic leg-level lesions that had been evolving for 3 months. The dermatological examination revealed a purpuric infiltrated placard on the anterior surface of the left leg (Fig. 1).
