This project is a pilot study to determine if use of the J-Tip Needle-Free Injection System, used to administer local anesthesia, has any effects on the appearance of skin samples when viewed under a microscope compared with skin samples that have been injected with local anesthesia using a needle. If use of the J-Tip device for local anesthesia delivery is shown not to alter the microscopic appearance of skin, anesthesia for skin biopsies in the future may potentially be performed without a needle, allowing for less fear and pain.

This study is for patients with melanoma. This study is being done to answer if a 1-centimeter margin as good as a 2-centimeter margin at reducing the risk of melanoma returning.
