Dermatological telemedicine services are provided by using a high resolution digital camera, a dermatoscope, a computer system and a data processing programme.

Teledermatology is defined as practical dermatology which uses appropriate e-communication tools and information technologies. It includes diagnostics, consultations, therapy, transmission of medical data and education of medical doctors. The term teledermatology was introduced by Perednia and Brown in 1995, who used the new technology for remote dermatological consultation. Teledermatological diagnostics of a disease can be compared with traditional dermatological diagnostics in real time when the dermatological examination is carried out.

The most frequent symptoms of dermatological diseases are:

• Moles – a large number of moles, changes in colour, size and mole edges,
• Malignant melanomain the family,
• Acne vulgaris and other facial changes which persist and do not show signs of improvement after following the prescribed treatment,
• Long-term changes in scalp and nails,
• Localized skin redness with peeling,
• Extensive skin change,
• Sores that have not healed for a longer period,
• Chronic skin diseases which do not react to prescribed therapy.
