Abstract

Worldwide melanoma incidence and mortality are increasing (1). Despite the ongoing research, advanced melanoma is still incurable; therefore, the most appropriate solution seems to be early detection combined with complete surgical excision (2). Since the diagnostic protocol of suspicious lesions includes a complete excision with safety margins (2), the problem of unnecessary scarring is significant. The real challenge in this case is to have a properly formulated diagnosis before acquiring a biopsy. Currently available non-invasive techniques are coherence tomography, digital dermoscopy, and reflectance confocal microscopy. All these techniques allow for a presumptive diagnosis, but the most promising results are provided by reflectance confocal microscopy. Reflectance confocal microscopy (RCM) is an optical imaging technique that uses a laser diode as a source of coherent monochromatic light which penetrates the tissue and illuminates a single point. Light from the stimulated section is reflected and passes through a filter, thereby forming the image on the detector. This filter enables selective excitation of a particular point on which focus is achieved and rejects reflection from the out-of-focus area, thus obtaining a "co...Continue Reading
