Dermoscopy for skin cancer detection

The worldwide incidence of melanoma and nonmelanoma skin cancers is increasing alarmingly. The development of new techniques such as dermoscopy leads to a consequent progress in skin cancers screening. The purpose of this review is to highlight recent advances in dermoscopy, reviewing primary research articles published in the last year.With the recent standardization of diagnostic procedures obtained by the Consensus Net Meeting on Dermoscopy and the definition of new melanoma-specific criteria, the efficacy in early melanoma diagnosis is improved. Dermoscopy is cost effective, leading to a decreased number of excised benign lesions, and the dermoscopic follow-up allows early detection of melanomas. However, the technique must be performed by experts in order not to miss melanomas. For this reason, instruction in dermoscopy is mandatory. Moreover, computer-aided diagnosis has been tested to be a valid support for physicians. Teledermoscopy is a new tool that allows a second expert opinion to manage atypical lesions.Dermoscopy opens up a new dimension on clinical morphology of skin lesions. Digital follow-up examinations, computer-aided diagnosis, and teledermoscopy are new facilities that will change the current management of skin cancers in general and melanoma in particular. Dermoscopy in the hands of experienced physicians has higher discriminatory power than naked-eye examination to detect skin cancers.
