title: Scabies presenting as a necrotizing vasculitis in the presence of lupus anticoagulant.
abstract: A 75-year-old man presented with a progressive eruption of 6 weeks' duration. Purpura and focal areas of cutaneous infarction were present on the legs. There were scabies burrows on the wrists and hands, and a mite was extracted. Histology of a skin biopsy showed a necrotizing leucocytoclastic vasculitis. Circulating lupus anticoagulant was detected. Treatment consisted of topical 5% permethrin cream and systemic steroids.
