Abstract
Cyclosporin A (CyA) has recently been introduced successfully for the treatment of the pustular forms of psoriasis. We treated a 57-year-old female cook who had been suffering from Hallopeau's acrodermatitis continue for 12 years. She came under our care for a marked worsening of the clinical picture of the third finger of the right hand. We treated her with CyA at an initial dose of 4 mg/kg per day. After two months of therapy the finger had completely healed. No side-effects were noted, confirming the efficacy and safety of cyclosporin A in the treatment of acrodermatitis continue at low dose.
