Capillaroscopy for noninvasive scabies diagnosis
Scabies diagnosis is confirmed by the microscopic identification of mites, eggs or the mite's faeces (scybala) in skin scrapings.

This is an invasive and, particularly for children, obnoxious procedure. Noninvasive techniques for in vivo imaging of scabies include dermoscopy, videodermoscopy and reflectance confocal microscopy.

Published in the British Journal of Dermatology, the authors recently explored capillaroscopy as a substitute for scraping for the noninvasive in vivo confirmation of scabies. The image demonstrates a mature female mite (Sarcoptes scabiei var. hominis) within a typical burrow (VideoCap 3.0 Reuma; DS Medica, Milan, Italy; original magnification × 200).

The inset shows the sampling site (arrow). Suspected burrows were located during clinical examination and visualized within approximately 10 min.
