“…All cases of scrofuloderma also had white structureless areas corroborating the associated scarring evident clinically. Follicular plugging in LV was reported to be higher in the present series than in literature and was also appreciated in PNT [4]. The serosanguineous crust was noticed in most patients with scrofuloderma and represented sinuses seen clinically; at places, there was an overlying hemorrhagic crust.…”

“…All the patients with LV, the majority (80%) with scrofuloderma, and the single patient with PNT in the presented series showed yellow-orange structureless areas. Ankad et al, in their series of 19 cases with LV, reported the presence of yellow-white globules instead of the yellow-orange structureless areas explained due to a predominance of Fitzpatrick skin type IV/V in their patients [4]. Although most cases in the current series also had Fitzpatrick Linear vessels with or without branches were frequently observed in LV and represent dilated capillary loops that appear well focused because of their displacement towards the epidermis by the underlying granulomas.…”

“…The application of dermoscopy for granulomatous diseases is gaining recognition as it gives a swift clue to the diagnosis much before histopathology results are accessible. The most available literature is on dermoscopy of LV, including a significant case series from India of 19 cases [4]. For other clinical types, there are anecdotal reports or small case series.…”

Introduction: Cutaneous tuberculosis is an uncommon form of tuberculosis, accounting for 1-2% of all forms of extra-pulmonary tuberculosis. Knowledge of the dermoscopy characteristics of different clinical types of cutaneous tuberculosis can help timely diagnosis resulting in better outcomes. Materials and methods: All clinically suspected and biopsy confirmed cases of cutaneous tuberculosis seen from July 2019 through December 2021 were retrospectively recruited. Information including age, gender, disease duration, site and morphology of lesions, and presence of concomitant tuberculosis elsewhere was noted. Two investigators retrospectively reviewed the dermoscopic characteristics of these cases. Results: Twenty-two patients comprised of 12 women and ten men met the inclusion criteria. Lupus vulgaris was the commonest presentation of cutaneous tuberculosis seen in 13 patients. Five had scrofuloderma, two had tuberculosis verrucosa cutis and one patient each had lichen scrofulosorum and papulo-necrotic tuberculid. Yellow-orange structureless areas (100%), linear/dot vessels (100%), white scales (92.3%), and white structureless areas (84.6%) were the predominant dermoscopy findings in lupus vulgaris. In scrofuloderma, linear vessels and white structureless areas were visible in all cases. Dirty white scales with a papillated surface were characteristically seen in tuberculosis verrucosa cutis, with one of the two patients each showing vessels and yellow-orange structureless areas. White globules with surrounding erythema were seen in lichen scrofulosorum and yellow-orange structureless areas with keratin plugs in papulo-necrotic tuberculid. Conclusion: A thorough understanding of the characteristic dermoscopy of cutaneous tuberculosis can help suspect the diagnosis early resulting in better management opportunity.

Over the last three decades, the use of dermoscopy has been extended to inflammatory and infectious dermatoses. Regarding the latter, while the first applications concerned skin parasitoses, there has been a significant increase in the publication trend regarding nonparasitic dermatoses over recent years, yet data on this topic are sparse and often lack a standardized analytical approach. This systematic literature review summarizes published data on dermoscopy of 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 152 papers addressing 43 different dermatoses and describing 184 different dermoscopic findings were included in the analysis. The majority of them displayed a level of evidence of V (107 single case reports and 40 case series), with only 5 studies showing a level of evidence of IV (case–control studies). Moreover, our analysis also underlined a high variability in the terminology used in published articles (even for the same dermatosis). Therefore, despite significant potential, future studies designed according to a systematic and standardized approach are required for a better characterization of dermoscopy of nonparasitic skin infections. Supplementary Information The online version contains supplementary material available at 10.1007/s13555-022-00855-2.

Lupus vulgaris (LV) is a type of paucibacillary cutaneous tuberculosis that can occur due to inoculation, lymphatic, or hematogenous route. It occurs in a previously sensitized individual with high immunity to tuberculosis. LV can have different morphology of presentation, which can lead to difficulty in diagnosis. The Tuberculin test is strongly positive. Histopathology will show epithelioid granulomas in the superficial dermis and acid‐fast bacilli rarely demonstrable within the granulomas. Dermoscopy will show focused linear vessels on a yellow to orange background. Culture is the gold standard for diagnosis, but its positivity rate is low. Mycobacterium tuberculosis bacilli can be detected using polymerase chain reaction from the lesions. Histopathology, tuberculin test, dermoscopy, molecular test, and culture would help diagnose LV. This review discusses the introduction, pathogenesis, clinical features, differential diagnosis, investigations, complications, and treatment of lupus vulgaris in detail. This review can help the dermatologist understand the condition better with appropriate diagnosis and therapy.
