Correlation of Dermoscopic Findings With Histopathological Features and Invasion Depth in Cutaneous Squamous Cell Carcinoma

This is a retrospective study including patients diagnosed with cutaneous squamous cell carcinoma between 2016 and 2025. Demographic, clinical, histopathological, and dermoscopic data were obtained from hospital records. Dermoscopic images taken with the FotoFinder dermoscope were independently evaluated by two dermatologists in a blinded manner. In addition, images were labeled using computer software and analyzed to measure the proportion of specific dermoscopic structures within the total lesion area. These quantitative data were used to examine the relationship between dermoscopic features and histopathological findings.
