Validating an open access and low-cost 3D-printed dermatoscope for enhanced accessibility into dermoscopy

Traditional dermatoscopes remain expensive and therefore relatively inaccessible, particularly in the resource-poor and nonspecialist setting. To address this concern, we have developed a self-assembly three-dimensional (3D)-printed dermatoscope, which has an estimated total cost of £5–20. No significant difference between traditional and 3D-printed dermoscopy has been demonstrated. Thus, the use of our self-assembly 3D-printed device is validated as a reliable tool for diagnosing benign lesions that is equal to traditional dermoscopy on the lesions tested. Such 3D-printed dermatoscopes have the potential to improve access to dermoscopy significantly where it is currently limited because of financial or other constraints.
