“…Using dermoscopy at 40x magnification, the 'jet with contrail' sign appears in the form of a small brown triangular structure (anterior part of mite) trailed by a linear segment (a burrow with or without eggs, and fecal pellets). Similar signs with different terminologies for the anterior part of the mite were identified [69] such as: 1) the "delta glider" sign [70] ; 2) the "hang-glider" sign [71] ; 3) the "circumflex accent like sign" [72] ; 4) the "delta-wing" sign [73] . Dermoscopic diagnosis can be enhanced by applying ink to the lesion, revealing a live mite [74] .…”

Zoonotic arthropods Myiasis (myia, Greek word for "fly)The chief zoonotic potential occurs in humans through skin invasion by the developing larvae (maggots) of Diptera. Infested larvae feed on dead or living tissues of the skin [9] . The recorded prevalence of the disease relies only on published case reports. Myiasis is considered a differential diagnosis of skin diseases in tropical poor communities due to bad hygiene and poor housing conditions [10,11] . However, human myiasis may also occur in countries with enhanced hygiene, as reported from New York [12] , and in France [13] . Notably, in temperate countries, myiasis occurs in summer when fly breeding is at its maximum [14] . Predisposing factors involve skin cancers, diabetes, and vascular diseases [10,15] . Nosocomial infection with Sarcophaga larvae was recorded revealing the ability of maggots to reach to

“…Upon microscopic correlation, triangular structure corresponded to the pigmented anterior section of mite, while the ‘contrail‐shaped’ structure represented the burrow with/without eggs and faecal pellets. Subsequent studies detected similar clues, 10–27 though different terminology has been used to refer to the anterior part of the mite, including ‘delta glider’ sign, 15,16,26 ‘hang‐glider’ sign, 17,20,21,22,25 ‘circumflex accent‐like’ sign 16 and ‘delta‐wing’ sign 19,28 . Application of ink can enhance the appearance of dermoscopic findings, 29 and movement of mite inside the burrow may also be highlighted on high‐magnification dermoscopy 12,14 .…”

Besides classic applications, dermoscopy has gained significant appreciation also for non‐tumoral dermatoses (general dermatology). In this field, skin parasitoses (infestations), bites and stings have been reported among the conditions that may benefit most from dermoscopic examination. However, published data on this topic are sparse and often lack a standardized analytical approach. In this systematic review of the literature, we sought to summarize available data on dermoscopy of cutaneous parasitoses, bites and stings, analysing dermoscopic features and used setting (polarization or not/magnification), pathological correlation and level of evidence of published studies as well as trying to align dermoscopic terminology of reported findings following a standardized methodology. A total of 150 publications addressing 29 different dermatoses and reporting 96 different dermoscopic findings were included in the analysis. Most of them displayed a level of evidence of V (113 single case reports and 36 case series), with only one study featuring a level of evidence of IV (case–control study). Additionally, our analysis also displayed poor uniformity in the terminology used in published articles (even for the same dermatosis). Therefore, albeit promising, dermoscopy of cutaneous parasitoses, bites and stings needs future systematized studies for a better characterization.

“…RCM is a real‐time, dynamic, non‐invasive skin detection device that can observe tunnels, mites, eggs, and feces in real‐time in the body. 21 In these microscopic features, it is highly specific to find scabies mites, scabies eggs, or dung ball structures for the diagnosis of scabies, and scabies can be diagnosed when one of the three is found under RCM, dung ball is the most common feature of reflex confocal microscope in scabies, and its sensitivity and specificity are high. It is of great significance to diagnose scabies.…”

ObjectiveTo summarize the image features of dermatoscopy and reflectance confocal microscopy (RCM) in children with scabies, and to explore the clinical significance in the diagnosis of children scabies.MethodsA retrospective analysis was conducted on 102 children scabies diagnosed clinically in the dermatology outpatient department of Tianjin Children's Hospital from April 2018 to June 2022. All children were examined by dermatoscopy and RCM, and images were collected.Results102 patients, 92 patients (90.2%) showed characteristic dermoscopic manifestations: white tunnels and small brown or dark brown triangular structures at their ends. 91 patients (89.2%) showed characteristic reflectance confocal microscopic manifestations: tunnels, scabies mites, feces, and eggs in the epidermal layer. All patients showed different degrees of non‐specific manifestations of dermoscopy and RCM.ConclusionChildren scabies have typical dermatoscopic and reflectance confocal microscopic characteristics, and dermatoscopy and RCM are effective non‐invasive diagnostic methods with high clinical application value in the diagnosis and differential diagnosis of children scabies.
