Vertical plane ex vivo dermoscopy: a novel dermoscopic technique. A preliminary study

Marcus Maia et al. An Bras Dermatol. 2018 Nov/Dec.

Abstract

Dermoscopic examination allows visualization of horizontal images on the skin, showing well-defined patterns. The authors propose ex vivo dermoscopic visualization using a vertical view of skin sections. The new image clearly distinguishes the stratum corneum, epidermis, and dermis as well as the anatomical location of the pigment. Will this new approach be useful in dermoscopic diagnosis? Further studies are needed.
