To assess the diagnostic accuracy of electrical impedance spectroscopy paired with an automated classification algorithm to differentiate malignant melanoma from benign skin lesions.
Conducted a multicenter study across 12 European clinics measuring electrical impedance spectra on skin lesions.
Trained an automated classification algorithm on 285 histologically confirmed lesions.
Evaluated diagnostic accuracy using an independent blinded cohort of 210 lesions (148 benign lesions and 62 malignant melanomas, including 38 with Breslow thickness ≤1 mm) across 183 patients.
Observed diagnostic sensitivity for malignant melanoma was 95% (59/62).
Observed diagnostic specificity for benign skin lesions was 49% (72/148).

Implication

Multicenter diagnostic study reveals high sensitivity but moderate specificity for melanoma detection, suggesting the need for refined algorithms before routine clinical adoption.
