[Abstract] Objective:To investigate the diagnostic value and clinical significance of dermoscopic image analysis technique for black heel disease (heel petechiae). Methods:Three patients with black heel disease were randomly seen with four lesions, and the diagnosis was first made by dermatoscopic image analysis technique and then confirmed by histopathology, and the results were retrospectively analyzed. RESULTS:Black heel disease had characteristic diagnostic features in dermatoscopic images-“pebble-like structures on ridges”-that corresponded well with histopathological findings, and these features were consistent with those reported in foreign literature. Conclusion:Dermatoscopic image analysis is a non-invasive, simple and reliable examination method, which avoids the conclusion that only blind surgical biopsy is required to differentiate melanoma from melanosis.
