Dermoscopy for the in vivo detection of sarcoptes scabiei

Dermatology. 2004;208(3):241-3. doi: 10.1159/000077310.

Abstract

We report the case of an 80-year-old patient who had intense pruritus which did not respond to a 3-month treatment with topical corticosteroids. On dermoscopy examination of the excoriations, we found the typical dermoscopic aspect of the scabies mite at a distance. Dermoscopy allows identifying a triangular structure which corresponds to the anterior section of the mite including the mouth part and the 2 pairs of front legs. This aspect has been described as resembling a jetliner with its trail, a delta glider or a spermatozoid. Traditional diagnostic methods for scabies failed in this case because the mites were at a distance from the burrows. This was due to the fact that the reaction to the mite was less pronounced and the diagnosis is frequently missed. Dermoscopy is a useful tool for the diagnosis of scabies either as a diagnostic test or to guide the traditional diagnostic tests.
