Teledermatology has developed over the last 30–40 years. Numerous studies have investigated combinations of computer, video, telecommunications and camera equipment to deliver dermatological advice to patients at a distance. Most were small pilot projects examining systems and equipment, usually abandoned subsequently. However, they demonstrated that it is possible to transmit diagnostically useful clinical data with supporting images from referring clinicians to a distant dermatologist to seek advice on diagnosis and management of patients. Of all applications of telemedicine, teledermatology may be the most appropriate.
