Lichen aureus.
Lichen aureus is a localized variant of pigmented purpuric dermatitis (PPD) and is rarely reported. A case of lichen aureus in a 28-year-old woman and a 13-year-old boy are presented. Biopsy results revealed the characteristic pattern of lichen aureus, including diffuse deposition of hemosiderin and dermal infiltrate of lymphocytes and histiocytes, some of which had Birbeck granules in the cytoplasm. The former case is unusual for its zosteriform distribution and localization (lower abdomen).
