Lichen aureus: a case report.

Lichen aureus (LA) is a distinctive, rare disease occurring predominantly in males, characterized by solitary rust- or copper-coloured patches of lichenoid micropapules, often present on fingers and calves. A case of LA in a 41-year-old male is presented. Biopsy revealed the characteristic pattern of LA, including a dense dermal infiltrate of lymphocytes and histiocytes containing haemosiderin. No epidermal changes were present.
