Diagnostic accuracy and interobserver concordance: teledermoscopy of 600 suspicious skin lesions in Southern Denmark.

In this large prospective study, no significant difference in sensitivity was observed between FTF and TDS, but specificity was lower on TDS than FTF. Taking management plans into account, we would, however, potentially have dismissed 2 of 23 melanomas, if only TDS had been used for assessment. One of these was a melanoma located on the scalp, an anatomic region less suitable for TDS.
