Alternative uses of dermoscopy in daily clinical practice: An update

      Dermoscopy is a noninvasive diagnostic tool that is currently being used for neoplastic skin lesions, several inflammatory and infectious diseases, and skin appendage disorders. As the clinical applications of dermoscopy beyond pigmented lesions are constantly increasing, the aim of this article is to provide an update on this topic. This comprehensive review substantiates how several diseases may show peculiar dermoscopy features so as to enhance the diagnosis and avoid (in selected cases) unnecessary histologic confirmation. In other cases, dermoscopy features may be shared with other conditions, with the advantage of narrowing down the differential diagnosis by ruling out those dermatoses with similar clinical aspect but different dermoscopic presentation.

      • Dermoscopy in lymphoproliferative disorders—experience from a cutaneous lymphoma clinic in a tertiary cancer center
        Journal of the American Academy of DermatologyVol. 80Issue 6
        • Preview
          To the Editor: We read with interest the review by Micali et al1 providing a comprehensive update on the use of dermoscopy beyond pigmented lesions. Data on the role of dermoscopy in the diagnosis of lymphoproliferative disorders (LPDs) have grown significantly in the past 5 years with the publication of case reports, case series, and large studies reporting on the dermoscopic features of specific cutaneous lymphoma subtypes.1,2 Several publications concluded that LPDs demonstrate characteristic dermoscopic patterns reflective of the specific lymphoma type and that their features differ from those seen in inflammatory skin conditions.
