Abstract: The Nevigraph is a credit card sized (2.25?×3.25?) plastic card designed for use in dermatology offices and given to patients to monitor any mole changes over time between dermatologist visits. It includes a millimeter ruler, a range of 10 shades of brown/black with holes to place over the mole while comparing color, a place for the dermatologist to record the mole location, a space for the dermatologist to put their contact information, and a back side that includes descriptions and example pictures illustrating the ABCDEs of dermatology.
