Abstract
Epstein-Barr virus (EBV) is a human oncogenic herpesvirus. Recent studies suggest that NK/T cell lymphocytosis associated with EBV infection often shows characteristic cutaneous manifestations such as ‘hydroa vacciniforme’ or ‘hypersensitivity to mosquito bites’. In this report, we described pathogenic roles of latent or lytic infection of EBV to explain induction mechanism of these cutaneous manifestations.
