abstract = {Accurate melanoma diagnosis is crucial for patient outcomes
and reliability of AI diagnostic tools. We assess interrater
variability among eight expert pathologists reviewing
histopathological images and clinical metadata of 792
melanoma-suspicious lesions prospectively collected at eight
German hospitals. Moreover, we provide access to the largest
panel-validated dataset featuring dermoscopic and
histopathological images with metadata. Complete agreement
is achieved in $53.5\%$ of cases (424/792), and a majority
vote ( ≥ five pathologists) in $90.9\%$ (720/792).
Considerable discordance is observed for non-invasive
melanomas (complete agreement in only 10/73 cases). The
expert panel disagrees with the local pathologists' and
dermatologists' diagnoses in $14.9\%$ and $33.5\%$ of cases,
respectively. This variability highlights the diagnostic
challenges of early-stage melanomas and the need to
reconsider how ground truth is established in routine care
and AI research. Including at least two pathologists or
virtual panels may contribute to more consistent diagnostic
results.},
