History:

 A 50-year-old woman with long history of atopic dermatitis presented in winter with chilblains-like pruritic, red-purplish, scaly patches and plaques with some fissures and erosions involving  chiefly the hands especially the dorsal surface of the fingers and also the feet with few lesions on the trunk of two months duration. A superpotent corticosteroid in ointment base (Clobetasol) twice daily plus antihistaminics greatly improved the rash within 2 weeks.
