“…Cydnidae bugs, also known as the burrower bug, belong to Chilocoris species that usually live inside the soil feeding on the roots of underground plants. When accidentally crushed, they release an orange‐brown pigment that stains the skin 120 . These pigmented macules should be distinguished by other pigmented lesions, including acral melanoma.…”

Sonthalia et al 121 described brown dots and globules of bizarre shapes having a stuck-on appearance, whereas brown dots, globules and criss-cross lines have been reported by Amrani et al 122,123 Finally, Jindal et al 120 revealed the presence of orange-brown streaks having ridge enhancement pattern (Fig. 3c) and further replicated the appearance using a drop of black fountain pen ink over the sole, thus suggesting that the pigment is released by the bug seeps through the skin dermatoglyphics.…”

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.

“…Four single reports described dermoscopic features of cydnidae pigmentation [57][58][59][60].The main feature consisted of brown dots/globules and/or lines [57,59,60]. Additionally, Jindal et al observed the presence of orange-brown structureless areas with ridge enhancement over the sole, thereby suggesting that the pigment released by the bug seeps through the skin dermatoglyphics [58].…”

Dermoscopy has been showed to facilitate the non-invasive recognition of several infectious disorders (infectiouscopy) thanks to the detection of peculiar clues. Although most of the knowledge on this topic comes from studies involving light-skinned patients, there is growing evidence about its use also in dark phototypes. This systematic literature review summarizes published data on dermoscopy of parasitic, bacterial, viral and fungal dermatoses (dermoscopic findings, used setting, pathological correlation, and level of evidence of studies) and provides a homogeneous terminology of reported dermoscopic features according to a standardized methodology. A total of 66 papers addressing 41 different dermatoses (14 bacterial, 5 viral, 11 fungal infections, and 11 parasitoses/bites and stings) and involving a total of 1096 instances were included in the analysis. The majority of them displayed a level of evidence of V (44 single case reports and 21 case series), with only 1 study showing a level of evidence of IV (case-control analysis). Moreover, our analysis also highlighted a high variability in the terminology used in the retrieved studies. Thus, although promising, further studies designed according to a systematic and standardized approach are needed for better characterization of dermoscopy of infectious skin infections.
