Overview of teledermatology in low-resource settings.

Telemedicine has grown significantly in recent years, relying in particular on the internet dissemination, that allowed the unprecedented development of networks between practitioners sometimes separated from very distant geographical areas. If technological progress has led to the implementation of telemedicine, its development is mainly due to its ability to meet real needs of health systems in low- and middle-income countries. Very visual in its medical practice, dermatology is well suited for telemedicine. In fact, many teledermatology networks are now operational which include the MSF teleexpertise system and the Africa Teledermatology Project. An overview of these teledermatology networks in low- and middle-income countries is proposed. Analysis of MSF teledermatology cases was used to assess their values and limitations.
