Epidermodysplasia verruciformis and generalized verrucosis: the same disease?
We report a patient with epidermodysplasia verruciformis (EV) who had severe generalized verrucous skin lesions for 50 years without any immunological abnormality. Microscopic examination showed two histopathological features, including seborrhoeic keratosis and common warts. The detected human papilloma virus (HPV) types were found to be HPV 3, 50, 5, and 76, using a degenerate PCR method. EV and generalized verrucosis are distinguished by slight differences in clinical symptoms or HPV types, so there should be no apparent differential points common to both diseases. Therefore, we propose that an abnormal susceptibility specific to HPV, which is the most characteristic feature in EV, should be regarded as a differential point in these two diseases.
