title: Refractory livedoid vasculitis responding to PUVA: a report of four cases.
abstract: Livedoid vasculitis is a chronic disease characterized by recurrent painful irregularly shaped ulcers, which heal with scars, most commonly located on feet or lower extremities. This condition is often resistant to the therapy. We report four cases with refractory livedoid vasculitis that responded to systemic psoralens and ultraviolet A radiation therapy.
