“…By contrast, the burrow of the mite correlates dermoscopically to the contrail feature eventually revealing multiple small brown dots, with the latter corresponding to fecal pellets. Subsequent investigations confirmed these previous findings and demonstrated the utility of dermoscopy in the diagnosis of scabies [23,24,25,26]. In a further recent trial comparing the dermoscopic diagnosis of scabies with the traditional ex vivo microscopic examination, it has been shown that dermoscopy achieves not only comparable high diagnostic sensitivity values as the standard ex vivo diagnosis (91 vs. 90%, respectively), but also improved the diagnostic skills for making treatment decisions even among inexperienced clinicians [27].…”

Entodermoscopy: A New Tool for Diagnosing Skin Infections and Infestations

Background: There is upcoming evidence that dermoscopy facilitates the in vivo diagnosis of skin infections and infestations. As such, dermoscopy connects the research fields of dermatologists and entomologists, opening a new research field of ‘entodermoscopy’. Objective: To provide an overview on the current applications of entodermoscopy. Methods: Systematic review of the English- and German-language literature by searches of Medline, Medscape and abstracts of the 1st World Congress of the International Dermoscopy Society. Results: Dermoscopic patterns have been described for viral warts, molluscum contagiosum, scabies, pediculosis, tinea nigra, tungiasis, cutaneous larva migrans, ticks and reactions to spider leg spines. Besides the diagnostic role of dermoscopy, there is increasing evidence that it can also assist in the monitoring of treatment efficacy for some of these conditions. Conclusion: Although most of the current available literature is based on single observations and small case studies rather than controlled trials, an increasing interest in this field can be observed.

“…From 1955 to January 2005, we found 61 dermoscopy articles reporting a variety of different indications in the context of NPSD [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61]. Preferentially we did not include dermoscopy articles in which the differential diagnosis to pigmented skin tumors was discussed.…”

“…For example, the so-called ‘jet with condensation trail’ has been shown to be specific for the diagnosis of scabies [15,16,17,18,19] and as a result, dermoscopy has replaced in our department the more time-consuming technique of the skin scraping. Dermoscopy can also be used for diagnosing pediculosis capitis and pubis, since the dermoscopic examination of affected hairs provides a sufficient magnification for identifying pediculus hominis and pthyrius pubis.…”

Dermoscopy improves the diagnostic accuracy in the clinical evaluation of pigmented skin lesions, but it is also useful for the assessment of vascular structures that are not visible to the naked eye. As a consequence, dermoscopy has been employed more and more for the differential diagnosis of nonpigmented skin disorders, including tumors but also inflammatory and infectious diseases. This article provides a review of the dermoscopic features seen in various nonpigmented tumoral and nontumoral skin lesions as well as the dermoscopic criteria used for monitoring skin reactions to various treatments.

“…The burrow of the mite – often shaped like an ‘s’ or ‘z’ [12] – correlates dermoscopically with the ‘contrail feature’ eventually revealing multiple small brown dots, with the latter corresponding to fecal pellets [11]. There are other studies verifying these data [13,14,15]. The presence of a ‘jet with contrail’ image representing the mite and its burrow has been reported to be 91% sensitive and 86% specific in the diagnosis of scabies [16].…”

Background:Sarcoptes scabiei causes mange in many domestic and wild mammals, and it has been reported to be transmitted from animals to humans. Canine scabies is known to infest humans, as well. Case Report: We report a 27-year-old woman who presented with severe pruritic papules on the trunk and arms. The patient reported that she had just bought a puppy which was also itchy. Direct microscopy from the dog showed scabies mites. The patient was treated by 5% permethrin which accomplished full recovery. Discussion: Canine scabies in humans is a challenging disease to diagnose since mites are hard to find on skin scrapings of dogs and the burrows that are the hallmark of scabies are absent. Dermatological examination of the lesions in our patient did not show any burrows or a specific dermoscopic image of scabies. Instead, we observed curvilinear crusts on most of the papules. Conclusion: To our knowledge, dermoscopic appearance of canine scabies in humans has not been described before. We think this special pattern of excoriations is the result of superficially dug tunnels that had been torn leaving vacant curved linear remnants behind, and this may provide a good support for the diagnosis of canine scabies contributing to the spectrum of entodermoscopy.
