INTRODUCTION
Periungual warts grow in the periungual or nail margin, damaging the nail bed and inhibiting nail growth1. Asymptomatic infection of HPV happens constantly, lesions appear as smooth, flat or slightly elevated papules, usually skin colored or may be pigmented. Most Lesions were controlled or cleared by cellular and humoral immune responses2. Thus, tissue erosion caused by warts has been rarely observed. Here, we first report a case of fingertip damage caused by periungual warts.
