title: Leukocytoclastic vasculitis associated with influenza A virus infection.
abstract: Leukocytoclastic vasculitis (LCV) usually presents palpable purpura characterized by inflammation of vessel walls and fragmentation of nuclei. Various conditions can cause LCV, and it can be induced by influenza A virus infection. We report a 2-yr-old Korean girl who presented palpable purpuric and hemorrhagic lesions with fever. She was diagnosed as LCV by skin biopsy, and influenza A virus was isolated from nasopharyngeal swab. She was treated with oseltamivir (Tamiflu®) and prednisolone with dramatic effect of vasculitis and fever.
