• Punch biopsy uses a cylindrical instrument that is rotated into the skin and removes a cylindrical specimen.
This method is used when tissue at a greater depth is required for diagnosis.
• Incisional biopsy removes a portion of the tumor with a scalpel.
• Excisional biopsy removes the entire lesion .
Because of the ease and minimal complications of these procedures, they can all be performed in the office, with local anesthesia being used to eliminate discomfort. Adverse effects include bleeding, infection and scarring.
