Glittering trail: Feces of scabies indicated by high-power-field dermatoscopy using UV-A light.

Adequate lighting sources and magnification are essential factors for observation of skin lesions. In addition to white light, the usefulness of ultraviolet light has been validated as a diagnostic tool because of its ability to detect both endogenous and exogenous fluorescence. 1 Zhang L.W.

Scabies is caused by the mite Sarcoptes scabiei, which lives in the stratum corneum of human skin. Although mite bodies can be barely detected using conventional dermatoscopy, further detailed observation is impossible because of technical limitations.
