Research into interobserver variability in diagnosis using teledermoscopy has so far been limited, but a recent study has reported good agreement between dermatologists from different continents using teledermoscopy.
Five dermatologists from New Zealand, Australia and the US were asked to view images of 979 lesions from 206 patients and record their diagnoses using MoleMap Diagnose. Interobserver variability between the diagnoses was analysed.
Four out of 5 dermatologists agreed on lesions that were agreed as melanoma and benign naevus. There was moderate to good agreement on seborrhoeic keratosis and basal cell carcinoma, but poor agreement for invasive squamous cell carcinoma. The ability to distinguish between malignant and benign lesions was good.
