Scabies is a highly contagious ectoparasitosis caused by the mite Sarcoptes scabiei hominis. Dermatoscopy, which allows the noninvasive, in vivo examination of the entire skin surface in a few minutes, has been demonstrated to be equivalent to scraping in terms of diagnostic accuracy. At low magnification (×10), it shows burrows and detects small dark triangular structures corresponding to the mites’ heads. Higher magnifications (>×100) provide detailed and unequivocal images of the mites, also allowing the detection of eggs and feces, usually not appreciable at lower magnifications. Dermatoscopy is also useful for the screening of asymptomatic contacts and family members and for post-therapeutic follow-up.
