[Dermatology in telemedicine. Possibilities and limits]

Telemedicine including teledermatology is the application of telecommunication technology for the purpose of diagnostics, planning and guiding of therapy and education. With the possibility to gain fast access to specialty knowledge, telemedicine makes it possible to deliver health care to patients at distant sites. By participating in telemedical consultations, patients receive accurate diagnosis in a rapid manner and save travel costs and time. Due to recent advances in computing and telecommunications technology, telemedicine will assume a more and more important role in future health care delivery. Telemedicine is utilized by almost all medical specialties but to varying degrees. Dermatology as a visually based specialty is predestined to use the various capabilities of telemedicine. The main applications so far include teledermatohistology and clinical teledermatology. The objective of this paper is to present the current status of teledermatology as part of telemedicine with a look toward future applications.
