Usefulness of dermoscopy/dermatoscopy to improve the clinical and histopathologic diagnosis of skin cancers

Multiple studies have shown that dermoscopy increases the sensitivity and specificity for the detection of skin cancers compared to naked-eye examination. Dermoscopy can also lead to the detection of thinner and smaller cancers. Furthermore, dermoscopy leads to more precise selection of lesions requiring excision. In essence, dermoscopy helps clinicians differentiate benign from malignant lesions through the presence or absence of specific dermoscopic structures. Therefore, since most dermoscopic structures have direct histopathologic correlates, dermoscopy can allow the prediction of certain histologic findings present in skin cancers, thus helping select management and treatment options for select types of skin cancers.
