A pediatric case of generalized lichen aureus.

Lichen aureus is a particularly rare subtype of pigmented purpuric dermatosis and is characterized by the sudden appearance of golden or rust-colored macules or needle-tip-sized flat papules (concentrated in one region to form lichenoid papules) on the lower limbs. These skin lesions are usually confined to an isolated, unilateral distribution, and linear segmental distribution is rare. In this report, we have documented one such case, where the lesions on the limb were arranged in strips (segmental distribution) that roughly followed the direction of the venous drainage. And the first attack and subsequent aggravation were both associated with the onset of allergic rhinitis, a Type I hypersensitivity.
