Area of Science:

  • Dermatology
  • Pathology

Background:

  • Lichen aureus is a rare, asymptomatic dermatosis.
  • It is classified within the pigmented purpuric dermatoses group.
  • Its etiology remains unknown.

Purpose of the Study:

  • To describe the clinical and histological features of lichen aureus.
  • To report on the natural course and resolution of the condition in a cohort of patients.

Main Methods:

  • Retrospective case series analysis.
  • Clinical observation of eight patients over 20 years.
  • Histopathological examination of skin biopsies.

Main Results:

  • The eruption presented as asymptomatic, lichenoid, erythematous-purpuric papules coalescing into patches, predominantly on the limbs.
  • Histology showed a normal epidermis with a dermal lymphohistiocytic infiltrate, extravasated red blood cells, and hemosiderin.
  • Five out of eight patients experienced spontaneous resolution within two to four years.

Conclusions:

  • Lichen aureus is a benign condition with a favorable prognosis.
  • Spontaneous resolution is common, suggesting observation without intervention is appropriate.
  • Further research into the etiology of lichen aureus is warranted.
