Lichen aureus

Lichen Aureus is a rare, chronic, and benign skin disease that is classified under the group of pigmented purpuric dermatoses (PPD). It is characterized by golden-brownish lichenoid macules and papules.

Etiology

The exact cause of Lichen Aureus is unknown. However, it is believed to be a type of hypersensitivity reaction to certain triggers such as infections, drugs, or other underlying diseases. Capillaritis is often associated with this condition.

Clinical Features

Lichen Aureus typically presents as a single patch or plaque with a golden or rust color. The lesions are usually located on the legs, but can also appear on the arms, trunk, and rarely on the face. The condition is usually asymptomatic, but some patients may experience mild itchiness.

Diagnosis

Diagnosis of Lichen Aureus is primarily based on clinical examination and histopathological findings. A skin biopsy is often performed to confirm the diagnosis. The histopathological features include a band-like lymphocytic infiltrate in the upper dermis, extravasation of red blood cells, and hemosiderin deposition.

Treatment

There is no specific treatment for Lichen Aureus. Management is usually aimed at controlling the symptoms and may include topical corticosteroids, oral antihistamines, and phototherapy. In some cases, the condition may resolve spontaneously.

Prognosis

The prognosis of Lichen Aureus is generally good. However, the condition can persist for many years and may cause cosmetic concerns due to the persistent pigmentation.
