title: Failure of etretinate in epidermodysplasia verruciformis.
abstract: In a patient suffering from benign lesions of epidermodysplasia verruciformis due to human papillomavirus type 5 little clinical improvement could be observed after 6 months of oral etretinate. The drug was given 75 mg/day for 1 month before dosage was reduced to 50 mg/day. Control biopsy after 3 months of treatment still revealed large quantities of virions and typical cytopathic effects in light and electron microscopic examination.
