title: Best way to perform a punch biopsy.
abstract: Nail punch biopsy is used to obtain a tissue sample for the diagnosis and treatment of nail diseases. The best results will be possible if the surgeon is familiar with the anatomy and physiology of the nail apparatus. A punch biopsy can be used in all regions of the nail apparatus in the presence or absence of nail plate. When the procedure is performed with a careful handling of the anatomic site and specimen, in most cases a successful diagnosis can be achieved.
