Longitudinal_Tile_Dermoscopic

Here we present a dataset derived from two longitudinal studies on general (n=196) and high-risk populations (n=284). The dataset includes longitudinal images of pigmented lesions extracted from 3 Dimensional (3D) TBP (on average, 521 lesions per person), and corresponding dermoscopic images for lesions that were larger than 5 mm and lesions that were of interest by either the participant or clinician (on average, 20 lesions per person). This dataset overall includes images of 250,162 skin lesions. For 165,251 of these lesions, longitudinal low resolution images (including 28 melanomas) and for 7,779 of these lesions corresponding longitudinal dermoscopic images (including 19 melanomas) are available. This dataset of skin images is accompanied by comprehensive individual-level metadata on lesion anatomic location, individuals’ number of naevi, demographics, skin cancer history, freckling, as well as sun exposure and sun protection behaviour data.
