Teledermatoscopy in Switzerland: a preliminary evaluation

Abstract

Background: Since devices for digital epiluminescence microscopy and for telemedicine have become affordable, a critical evaluation of this new method has been needed.

Objective: Our aim was a critical evaluation of teledermatoscopy under routine conditions in private practice.

Methods: Pigmented skin lesions (PSLs) scheduled for excision were documented with a digital epiluminescence microscopy (DELM) system. Images were sent to the PSL consultation at the Department of Dermatology of the University Hospital Geneva, where a diagnosis was established. The histopathologic report including the initial diagnosis was sent afterward. Both approaches were compared concerning diagnostic accuracy.

Results: Over a period of 6 months, 55 lesions on 51 patients have been included in this study. Picture quality was good or very good in more than 90%. Diagnostic accuracy of the teledermatoscopy approach was superior to that of the conventional approach for malignant melanocytic lesions.

Conclusion: We have shown the feasibility of a teledermatoscopic consultation. The gain of diagnostic accuracy in this teledermatoscopic approach, especially for malignant melanocytic lesions, suggests that patients might benefit directly from such a consultation at distance.
