We report a case of herpes zoster with generalized varicelliform eruption. A 56-year-old male presented with rice-sized erythematous grouped ruptured or crusted vesicles with a band-like distribution on the left chest and back and generalized rice-to-pea-sized erythematous vesicles on his whole body. Histologic examination revealed ballooning degeneration and multi-nucleated giant cells in the epidermis and leukocytoclastic vasculitis in the dermis.
