“…The DZ‐D100 dermoscope is a new digital camera supplied with a violet LED (405 nm) in addition to the common white light LED. Recently, Sano et al 6 . reported a similar case in which the border of melanoma was clarified using DZ‐D100 dermoscopy with VLD, but there was no description of histopathological examination of the lesion.…”

Malignant melanomas often present with irregular shapes and in multiple shades of brown under white light. 1 In pale-toned melanoma, it is often difficult to distinguish the boundary between the lesion and adjacent healthy skin with the naked eye, even with conventional dermoscopy (CDS). The DZ-D100 dermoscope (Casio Computer) is equipped with a violet light-emitting diode (LED), which is a near-ultraviolet (UV) light with a wavelength of 405 nm, in addition to a conventional white LED (Figure 1). Since the absorption wavelength of melanin contains violet light, the combination of CDS and violet-light dermoscopy (VLD) may reveal the distribution of subtle pigmentation of fine melanin in the skin, making it easier to distinguish between lesions and healthy skin.

The growing incidence of skin cancer, with its associated mortality and morbidity, has in recent years led to the developing of new non-invasive technologies, which allow an earlier and more accurate diagnosis. Some of these, such as digital photography, 2D and 3D total-body photography and dermoscopy are now widely used and others, such as reflectance confocal microscopy and optical coherence tomography, are limited to a few academic and referral skin cancer centers because of their cost or the long training period required. Health care professionals involved in the treatment of patients with skin cancer need to know the implications and benefits of new non-invasive technologies for dermatological oncology. In this article we review the characteristics and usability of the main diagnostic imaging methods available today.

“…Dermoscopy with ultraviolet light utilizes the fluorescence emitted by skin lesions to help detect superficial mycosis, nail diseases, Demodex mites, scabies, and pigmented diseases, and identify the demarcation of melanin distribution in cutaneous melanoma for complete excision. [11][12][13] Compared with Wood's lamps, dermoscopy with ultraviolet light does not require a dark room for image acquisition, but has a relatively small field of view and cannot replace Wood's lamps. 11 Handheld dermoscopy has no storage function and can only be achieved by externally connecting a smartphone or a digital camera.…”

Recent developments in dermoscopy for dermatology

Background: Dermoscopy is considered to be a bridge between clinical observation and histopathological examination, allowing the in vivo examination of skin microstructures that are not visible to the naked eye, from the epidermis to the superficial dermis. Dermoscopy has undergone rapid development, witnessing the history from natural light to polarized light, from handheld dermoscopy to videodermoscopy, and from classic dermoscopy to digital dermoscopy. Its application extends from the initial differential diagnosis of pigmented skin diseases (melanocytic and nonmelanocytic) to general dermatology, including appendage (nail and hair) abnormalities and diseases related to infection and inflammation. Aims:We aimed to provide the latest developments in dermoscopy from the perspective of handheld dermoscopy, videodermoscopy, fluorescence-advanced videodermatoscopy, polarized transilluminating dermoscopy, and digital dermoscopy. Methods:In this review, we searched the PubMed, Embase, Web of Science, and Cochrane Library databases for reviews, case reports, and observational studies on dermoscopy. Results:We provided an updated review of dermoscopy based on published literature. Conclusion:Dermoscopy is an indispensable diagnostic tool in dermatology, and it is expected to be further developed in the future.
