Although some details of nail diseases can already be assessed with the naked eye, many nail abnormalities often represent a challenge because many differential diagnoses including life-threatening nail-unit melanoma must be taken into consideration. Therefore, physicians are often unsure about their clinical diagnosis and lack confidence in managing nail lesions. Furthermore, nail apparatus biopsy may be necessary for definite diagnosis but is reluctant procedure because it is painful and can result in permanent nail dystrophy. Dermoscopy is already well-known as non-invasive diagnostic technique for the in vivo observation of skin lesions, allowing a better visualization of surface and subsurface structures. Recently, many and sometimes highly specific criteria for the dermoscopic assessment of nail diseases have been described in a series of published reports. Thus, dermoscopy also can be used to evaluate the nail apparatus, and it is helpful for diagnosis of numerous nail diseases and tumors. In addition, this can play the role to reduce the number of unnecessary surgeries and help physicians determine the most appropriate biopsy technique and site when biopsy is performed. To use the nail dermoscopy properly, however, the good knowledge of nail anatomy and physiology, and the pathogenesis of nail diseases is required. In this lecture, I would like to provide important diagnostic aids for a well-founded dermoscopic assessment of nail diseases.
