The amount of tissue that is excised is dependent on the nature of the surgical procedure. If a diagnostic procedure is performed, a small volume of tissue is removed so that histologic diagnosis can be achieved with minimal scarring. When surgery is performed to treat malignant disease, the aim is to excise the lesion with a clear margin in order to minimize the risk of local recurrence. [13]
