Group type: EXPERIMENTAL
Intervention: Nevisense 3.0
Description: Nevisense, an AI-based point-of-care system for the non-invasive evaluation of irregular moles remains the only FDA approved system available for melanoma detection in the US. Nevisense 3.0 will be used as a one-time exposure of \<8 seconds per lesion. Disposable electrodes that contact the participant are 5mm x 5mm in size. Nevisense 3.0 measures electrical impedance of skin lesions and provides an output called the electrical impedence spectroscopy (EIS) score. Electrical impedance is a measure of a material's overall resistance to the flow of alternating electric currents of various frequencies. The principle is that electrical impedance is different in normal versus abnormal tissue.

Group type: EXPERIMENTAL
Intervention: Dermlite Cam
Description: Dermlite Cam is a digital camera that captures images of the skin under cross-polarized and non-polarized light and is 510(k) exempt. The DermLite Cam device appears as a single piece camera with a charging cable and USB computer cable. As part of the camera unit, an extensor arm exists to allow for the capture of standardized clinical images. The DermLite Cam will be used to acquire 3 images of \<5 seconds per lesion (one clinical, one polarized dermoscopic, and one non-polarized dermoscopic). NOTE - for the purposes of this study, teledermatology images (dermoscopic and clinical - at approximately 6 inches, 12 inches, and 18 inches) were taken using the Barco Demetra after technical issues arose that prohibited the continued use of the Dermlite Cam.

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Skin biopsy
Description: A skin biopsy is a small procedure that removes a sample of skin from the surface of the body. The method utilized will be either a shave or punch technique. The maximum size of a punch biopsy will be 6mm and these wounds are generally closed with no more than 2-3 sutures. A skin biopsy takes \<15 minutes including preparation time, administration of intradermal anesthesia using lidocaine 1% with epinephrine 1:100,000, removal of the skin sample, achievement of hemostasis, dressing the wound, and providing instructions for home care. Samples will be placed formalin for routine processing.

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Barco Demetra
Description: Barco Demetra is a non-invasive skin imaging system, which acquires multispectral and white light dermoscopic images and clinical photographs of the skin which can then be stored, retrieved, displayed, and reviewed by medical practitioners. The Barco Demetra received 510(k) Premarket approval (K192829). The system involves a hardware imaging device and a stand-alone software application. The hardware device is a portable, battery-powered medical device for acquiring and visualizing images of the skin and uploads all images to cloud storage. The software application is cloud software with an associated web application; it can be used to visualize images and related data and can generate consultation reports. For the purposes of this study, teledermatology images (dermoscopic and clinical - at approximately 6 inches, 12 inches, and 18 inches) were taken using the Barco Demetra after technical issues arose that prohibited the continued use of the Dermlite Cam.
