Telepathology is the practice of pathology at a distance. It uses telecommunications technology to facilitate the transfer of image-rich pathology data between distant locations for the purposes of diagnosis, education, and research.

Telepathology has been successfully used for many applications, including the rendering of histopathology tissue diagnoses at a distance. Although digital pathology imaging, including virtual microscopy, is the mode of choice for telepathology services in developed countries, analog telepathology imaging is still used for patient services in some developing countries.

Telepathology is currently being used for a wide spectrum of clinical applications including diagnosing of frozen section specimens,primary histopathology diagnoses, second opinion diagnoses, subspecialty pathology expert diagnoses, education,compentency assessment, and research. Benefits of telepathology include providing immediate access to off-site pathologists for rapid frozen section diagnoses. Another benefit can be gaining direct access to subspecialty pathologists such as a renal pathologist, a neuropathologist, or a dermatopathologist, for immediate consultations.
