Vasculitis: Livedoid vasculopathy is an uncommon condition. If this is a confirmed diagnosis and other entities are ruled out, treatment options include: Pentoxifylline (trental) (400 mg 3 times/d), low molecular weight heparin, hyperbaric oxygen therapy and IV methylprednisolone. You should follow closely with your dermatologist or rheumatologist.
