Answer

To perform the biopsy, the base of the lesion is injected with 1% lidocaine, and an alligator-mouth biopsy forceps is used to obtain the specimen. Application of silver nitrate to the base of the biopsy site generally controls any bleeding, though in rare cases, suture placement may be required to achieve hemostasis.
