Bullous and pruritic variant of disseminated superficial actinic porokeratosis: successful treatment with grenz rays.

We describe a case of intensively pruritic and partially bullous disseminated superficial actinic prorokeratosis, with acute flare-ups. Histopathological examination showed the characteristic cornoid lamella and subepidermal blister formation in one biopsy. Grenz ray treatment resulted in a marked regression of the skin lesions and pruritus. Copyright (R) 2000 S. Karger AG, Basel
