“…Trombiculid larva were recently described in a case of trombiculiasis. 128 Dermoscopy of skin lesions due to trombiculiasis has been reported to show perifollicular, brown, striated halo with a granular, radiated arrangement and a hypopigmented central area with a sunburst appearance; an oval, follicular white structure was also present in the majority of the central areas. 129…”

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.

“…Trombiculidae sensu Kudryashova ( 1998 ), with more than 3000 nominal species worldwide (Liu et al 2013 ; Nielsen et al 2021 ), is the most species-rich family within terrestrial Parasitengona mites. Most species, recognized based solely on morphological criteria, are known exclusively from larvae, which parasitize various vertebrate and a few invertebrate hosts (Nadchatram 2006 ; Wohltmann et al 2006 ; Shatrov and Kudryashova 2008 ; Stekolnikov and Kar 2015 ; Stekolnikov et al 2016 ; Caputo et al 2018 ; Felska et al 2018 ; Kaya and Yilmaz 2019 ). Despite the large number of papers related to Trombiculidae (Actinotrichida: Parasitengona) published during the last 80 years, knowledge about ecological demands and biology of species remained scarce.…”

The study aims to ascertain the diversity of trombiculid species associated with Chiroptera in Poland, and for the first time in the case of research on Central European Trombiculidae, we use both DNA and morphology in an integrative taxonomic approach to determine species identities of trombiculids. The research was carried out from 2015 to 2019. In total, 2725 larvae were collected from 300 specimens of bats belonging to 11 species. Deutonymphs were obtained through laboratory rearing of larvae; few larvae and deutonymphs were collected also from bats' daily roosts. The presence of trombiculid larvae on hosts was observed between July and April of the following year, with the highest numbers recorded in autumn, during bat swarming. Male bats were infested more often than females (16.4 vs. 6.6%). The highest infestation rate was recorded for Barbastella barbastellus, Myotis nattereri and Plecotus auritus, and the highest prevalence of chiggers (> 30%) for Myotis bechsteinii and P. auritus. The larvae found on bats occupied the areas with free access to the host’s skin: auricles, tragus, and snout. Morphological identification of specimens to the species level was hindered by the mosaic distribution of diagnostic traits. Morphological analyses indicated the presence of Leptotrombidium russicum and Leptotrombidium spp. in the examined material, whereas molecular analyses additionally suggested three other potential species assigned to the same genus based on the assessed scope of intrageneric variation (ASAP method). We argue that the identification of the parasitic larvae (chiggers) using morphological characters does not address the question of actual species boundaries, which, in turn, affects the inferences about host specificity and host range.

Background: Mites are among the smallest arthropods that can be seen without magnification, were the use of dermatoscopy is an invaluable tool. They are a cosmopolitan pest, and at the moment more than 250 species have been shown to produce problems for humans and animals alike. These mites are capable of producing a wide array of clinical signs and symptoms, from local to systemic, from mild to severe, as well as transmitting pathogens. This study aimed to provide an update to the clinical impact on human health, the distribution and species involved in the clinical conditions produced by trombiculids through a systematic review.

This study aimed to provide an update to the clinical impact on human health, the distribution and species involved in the clinical conditions produced by trombiculids through a systematic review. Methods: A systematic literature review was conducted in Medline, Lilacs, Redalyc, Scopus, SciELO and Google Scholar, were we use as a threshold of publication date the year 2008. We limited the search strategy to articles published in Portuguese, French, English and Spanish. Eligible studies were case reports and case series that reported outcomes in humans caused by trombiculid bites. Patient-level and study-level information was extracted. Results: The literature search yielded 832 studies; 13 were case reports, 4 case series and 2 descriptive studies reporting a total of 49 cases. Most patients were male, and the median age was 33.7±6.4 years old. The most frequently reported symptoms were local erythema, pruritus and papules. No deaths were documented. Trombiculids from the genera Trombicula, Eutrombicula and Leptotrombidium appear to be the most commonly reported. Discussion: Trombiculiasis is an infestation caused by the larval stage of various types of mites, known as chiggers, they belong to the class Arachnida and the family Trombiculidae. This systematic review provides an overview of the trombiculids of clinical importance, their distribution and effects of the bite on human health. Our results show that there are different species of mites that can have important consequences for human health. No fatal cases owere registered.Even so, the transmission of scrub typhus is important and remains one of the most life-threatening rickettsial infections in some regions of Asia. Conclusions: The bite of different species of trombiculids around the world can cause a wide array of clinical consequences to human health. Even as mortality appear to be nonexistent, trombiculid bites must be adequately diagnosed and treated properly: A systematic literature review was conducted in Medline, Lilacs, Redalyc, Scopus, SciELO and Google Scholar, were we use as a threshold of publication date the year 2008.
