EditorThe diagnosis and treatment of livedoid vasculopathy is a challenge to the clinician. 1 A 47-year-old patient presented with livid reticular discoloration and ulceration on both legs, aggravated by exposure to cold since the age of 26 years. Clinical examination revealed painful focal purpuric ulcerating lesions, atrophic scarring, teleangiectasia, hemosiderin deposits and hyperpigmentation (Fig. 1a). Laboratory parameters such as coagulation factors, phospholipid antibodies, ANA, ENA, ANCA, C3, C4, immunocomplexes, C-reactive protein, cryoglobulins, cold agglutinins, erythrocyte sedimentation rate, serum protein electrophoresis, and urine were normal or negative. Repeated MRIs of the brain, X-rays of the chest and ultrasound investigations of the abdomen were normal. A skin biopsy specimen revealed dermal thickened vessel walls and fibrin deposits with occasional obliteration. Since 1983
