Incisions should be made in an oval-shape excision with at least a 1-mm margin around the lesion. The incisions must be made throughout the entire depth of the dermis and include any visible subdermal extension. Primary closure is usually required, although some excisions (eg, < 1-cm circular incisions on the back) are best left to heal by secondary intention. This yields the most appealing-looking scar on the back. In all other areas, nonabsorbable suture is commonly used to close these wounds. As a general rule, the sutures are left in 5-6 days for facial areas; 10-14 days on the extremities and scalp, which receive more daily trauma; and 7-10 days for all other areas.
