Abstract
Tinea capitis is a widespread fungal infection that is even more common in rural areas of the world predominantly among children. The diagnosis of the infection and the identification of the responsible dermatophyte are determined by potassium hydroxide mount microscopy, Wood's lamp examination and mycological culture of the skin scrapings and hair samples. Nevertheless, this conventional setting has several limitations such as lack of availability, low sensitivity and specifity, and particularly prolonged turnaround time for fungal culture. Trichoscopy is a well-proven practical and beneficial aid to faciliate the diagnosis of scalp and hair disorders. Studies performed during the last 15 years revealed several characteristic trichoscopic findings of non-inflammatory tinea capitis namely comma hairs, corkscrew hairs, Morse code-like hairs and zigzag hairs. Thereby, trichoscopy has proved itself in the establishment of prompt diagnosis of TC, identification of the responsible fungus enabling to appropiate treatment on time, and evaluating treatment response by screening the clearance of the trichoscopic features.

Abstract
BACKGROUND The incidence of alopecia areata (AA) has increased over the last few decades. Trichoscopy is a noninvasive procedure performed in dermatology clinics and is a helpful tool in determining the correct diagnosis of hair loss presentations. OBJECTIVE Through mapping the researches that have been done to represent the spectrum of trichoscopic findings in AA and to identify the most characteristic patterns. METHODS Thirty-nine studies were eligible for the quantitative analysis. Meta-analysis and subgroup analysis were performed. RESULTS Thirty-nine studies (29 cross-sectional, five retrospective, two descriptive, one case series, one observational, and one cohort) with a total of 3204 patients were included. About 66.7% of the studies were from Asia, 25.6% from Europe, and 7.7% from Africa. The most characteristic trichoscopic findings of AA were as follows; yellow dots, black dots, broken hairs, short vellus hairs, and tapering hairs. CONCLUSION There is no single pathognomonic diagnostic trichoscopic finding in AA rather than a constellation of characteristic findings. The five most characteristic trichoscopic findings in AA are: yellow dots, black dots, broken hairs, short vellus hairs, and tapering hairs. Yellow dots and short vellus hairs considered the most sensitive clues for AA, while black dots and tapering hairs are the most specific ones. Furthermore, trichoscopy is a useful tool that allows monitoring of response during the treatment of AA. Treatment responded cases will show an increase in short vellus hairs, but loss of tapering hairs, broken hairs, and black dots, while yellow dots are the least responsive to the treatment.

Abstract
Alopecia areata is an autoimmune disease that affects the hair follicle and can present as bald patches on the scalp and hair loss in other parts of the body. Diagnosis is clinical but can be aided by trichoscopy, a simple, rapid technique that reduces the need for invasive procedures and can also help with monitoring treatment response. We review the usefulness of trichoscopy in alopecia areata. The most common trichoscopic findings are yellow dots, black dots, exclamation mark hairs, short vellus hairs, and coudability hairs. Other, less common, findings can also help establish a diagnosis. Good response to treatment is indicated by the disappearance of black dots, broken hairs, and exclamation mark hairs. The observation of yellow dots, by contrast, indicates chronic disease and poor response to treatment.

Abstract
OBJECTIVE Pediatric patients often reveal localized alopecic foci on the scalp. The essential point upon approaching a child with localized alopecia is distinguishing the two most common causes, alopecia areata and tinea capitis, as their treatments are entirely different. Although potassium hydroxide examination is the preferred method for their clear distinction, dermatoscopy is also emerging as a rapid diagnostic tool. This study aimed to assess and compare the dermatoscopic findings of alopecia areata and tinea capitis. MATERIALS AND METHODS Enrolled in this study were 34 children with tinea capitis and 21 children with alopecia areata admitting to a single-center outpatient clinic between 2017-2021. The authors confirmed all children's diagnoses by an integrative evaluation of clinical features, potassium hydroxide examination results, and treatment response patterns. Clinical features and the variables of interest (dermatoscopic findings) were investigated through the medical records and the baseline dermatoscopic images. RESULTS The most common dermatoscopic finding within the tinea capitis cohort was comma hairs, detected in 33 (97.1%) of the patients. Other findings of the tinea capitis group included squamation (n=31, 91.2%), broken and dystrophic hairs (n=30, 88.2%), corkscrew hairs (n=24, 70.6%), zigzag hairs (n=18, 52.9%), and pigtail hairs (n=9, 26.5%). The most common dermatoscopic finding within the alopecia areata cohort was exclamation mark hairs (n=13, 61.9%), that was followed by black dots (n=9, 42.9%), yellow dots (n=8, 38.1%), vellus hairs (n=6, 28.6%), and broken and dystrophic hairs (n=5, 23.8%). CONCLUSION Among the detailed evaluation of dermatoscopic findings of tinea capitis and alopecia areata patients, the only overlapping feature was dystrophic and broken hairs that could be present in both diseases; but were more common within the TC group than within the AA group (88.2% vs. 23.8%).

Abstract
BACKGROUND Tinea capitis is the most common pediatric dermatophyte infection. Optimal treatment regimen differs according to the type of the dermatophyte involved. OBJECTIVES The aim of this work was to study the trichoscopic signs in relation to isolated organism in a sample of Egyptian patients with tinea capitis and the possibility of using them as a guide for selection of appropriate antifungal. METHODS This study was carried out on 60 subjects with tinea capitis. Patients were mycologically examined, both direct microscopy with KOH preparation and culture of the scraped hair materials on Sabouraud dextrose agar. Culture mounts were used for identification of the organism. Trichoscopic examination of all patients was performed using the Dermlite DLIII dermoscope. RESULTS There was significant higher prevalence of both comma and corkscrew hair in endothrix infection and T. violaceum-infected cases. On the other hand, there was significant higher prevalence of zigzag, barcode hairs, and white sheaths in ectothrix infection and M. canis-infected cases. CONCLUSION While some trichoscopic findings are nonspecific, others were found to be more specific. Finding zigzag hairs and barcode hairs points to ectothrix infection (M. canis), and it is recommended to start treatment with griseofulvin. On the other hand, finding comma hairs and corkscrew hairs without zigzag hairs and barcode hairs points to endothrix infection (T. violaceum), and it is recommended to start treatment with terbinafine in the usual dose.

Abstract
BACKGROUND Hair loss (alopecia) is a common problem and is a major cause of psychological stress and anxiety among affected individuals. It is of utmost importance to diagnose these cases at the earliest and treat them accordingly. Trichoscopy provides a noninvasive option that can be used for early diagnosis and monitoring the progression of the hair disorders. AIMS AND OBJECTIVES To perform trichoscopy and document the findings in patients with nonscarring alopecia's. MATERIALS AND METHODS A total of 100 cases satisfying the inclusion criteria were screened for general physical examination and scalp examination including hair shaft and root, and tests for hair anchorage and fragility were also done. The lesions were examined through dermoscope, photographs were taken, and findings were documented. RESULTS Among the total of 100 cases screened, 57 were female and 43 were male. The mean age of the study group was 26 ± 14.8 years. Females were affected by alopecia areata (AA) and female pattern hair loss (29.8%) equally, whereas males were most commonly affected by AA (41.8%). The common trichoscopic follicular features noted were broken hair (48%), black dots (48%), single hair follicle unit (45%), short vellus hair (44%), upright hair (41%), and yellow dots (40%). The common interfollicular features seen were honeycomb pigmentation (26%) and arborizing red lines (12%). CONCLUSION The emergence of newer hair signs on trichoscopic studies aids in identification and has a definitive role in the diagnosis of clinically difficult cases, so it is recommended to use trichoscopy in the routine examination of nonscarring alopecia's.

Abstract
INTRODUCTION An increased incidence of tinea capitis has been observed over the last few decades. Trichoscopy is a non-invasive, in-office method helpful in establishing the correct diagnosis in patients with hair loss and inflammatory hair disorders. The objective was to review and analyze current data on the trichoscopy of tinea capitis. METHODS A systematic review of the literature was conducted using the PubMed, EBSCO and Scopus databases. The search terms included 'tinea capitis' combined with 'trichoscopy', 'dermatoscopy', 'dermoscopy', 'videodermatoscopy' or 'videodermoscopy'. RESULTS Of 326 articles, 37 were considered eligible for the quantitative analysis. The most characteristic (with a high predictive value) trichoscopic findings of tinea capitis included comma hairs (51%), corkscrew hairs (32%), Morse code-like hairs (22%), zigzag hairs (21%), bent hairs (27%), block hairs (10%) and i-hairs (10%). Other common, but not characteristic, trichoscopic features were broken hairs (57%), black dots (34%), perifollicular scaling (59%) and diffuse scaling (89%). Morse code-like hairs, zigzag hairs, bent hairs and diffuse scaling were only observed in Microsporum tinea capitis (8/29, 28%; 6/29, 21%; 4/29, 14% and 4/29, 14%, respectively). In Trichophyton tinea capitis, corkscrew hairs were more commonly detected compared to Microsporum tinea capitis (21/38, 55% vs 3/29, 10%). CONCLUSION The presence of characteristic trichoscopic features of tinea capitis is sufficient to establish the initial diagnosis and introduce treatment before culture results are available. Trichoscopy may be useful in distinguishing between Microsporum and Trichophyton tinea capitis.

Abstract
BACKGROUND/OBJECTIVES Trichoscopic findings characteristic of alopecia areata have been established in adults. The objective of the study was to assess trichoscopic findings in children with alopecia areata. METHODS Retrospective analysis of trichoscopic findings in 50 children (3-11 years old) and 50 adults (19-31 years old) with alopecia areata was performed. RESULTS Yellow dots were less commonly detected in children compared with adults (26/50, 52% vs 48/50, 96%). Pigtail hairs and empty follicular openings were more commonly observed in children compared with adults (14/50, 28% vs 2/50, 4% and 40/50, 80% vs 16/50, 32%, respectively). No significant difference in the frequency of other trichoscopic features between children and adults was found. Black dots, broken hairs, exclamation mark hairs, and tapered hairs were detected in 20/50 (40%), 27/50 (54%), 22/50 (44%), and 6/50 (12%) children, respectively, and in 26/50 (52%), 27/50 (54%), 20/50 (40%), and 11/50 (22%) adults, respectively. Triangular hairs (short hidden hairs), short vellus hairs, and upright regrowing hairs were observed in 22/50 (44%), 35/50 (70%), and 23/50 (46%) children, respectively, and in 24/50 (48%), 37/50 (74%), and 28/50 (56%) adults, respectively. Pohl-Pinkus constrictions were present in 2/50 (4%) children and 4/50 (8%) adults. CONCLUSIONS The most common trichoscopic findings of alopecia areata in children are empty follicular openings and short vellus hairs. Pigtail hairs and empty follicular openings are more commonly presented in children compared with adults. In contrast, yellow dots are less commonly observed in children compared with adults. Triangular hairs (short hidden hairs) are new trichoscopic findings of alopecia areata.

Abstract
AIM The purpose of the study was to describe the trichoscopic features of pseudonits and to assess the usefulness of trichoscopy in their differential diagnosis. METHODS A retrospective study was performed on those patients seen for the suspicion of head or pubic lice and who underwent trichoscopy with polarized light at ×10 magnification for a more accurate diagnosis. Forty-two patients (28 males/14 females, mean age: 34.5 years, range: 7-59) were evaluated. RESULTS In 30 cases, trichoscopy confirmed the suspicion of head (24 cases) or pubic (6 cases) lice, whereas in 12 cases it allowed for a final diagnosis of seborrheic dermatitis (5 cases), hair casts (3 cases), trichobacteriosis (2 cases), white piedra (1 case), and trichorrhexis nodosa (1 case), by showing different types of pseudonits. CONCLUSION Hair examination using trichoscopy in routine clinical practice may provide useful information for the correct diagnosis, ranging from common head and pubic lice infestations to rarer shaft abnormalities. Differentiating pseudonits from nits is essential to make the correct diagnosis in order to prevent unnecessary treatment, anxiety, and/or embarrassment.

Abstract
Trichotillomania is a form of traction alopecia resulting from repetitive and compulsive hair pulling and plucking. Trichotillomania and patchy alopecia areata may have similar clinical and dermoscopic features in some cases. On trichoscopic examination, the presence of black dots, coiled or hook hair, shafts of varying lengths with fraying or split ends (trichoptilosis), and an absence of exclamation mark hairs and yellow dots are suggestive of trichotillomania.

Abstract
Trichoscopy (dermoscopy of the hair and scalp) is a technique that improves diagnostic accuracy and follow-up with hair and scalp disorders. Although several studies of trichoscopy have been made in Caucasian and Asian populations, little has been published regarding trichoscopy findings in skin of color, despite the great prevalence of hair diseases in populations with this kind of skin. The aim of this review was to describe the trichoscopic features of normal scalp and of hair disorders in patients with dark skin phototypes. This will help dermatologists to distinguish between unique trichoscopic features of dark skin, and allow them to provide more accurate diagnoses and treatments for these patients.

Abstract
Dermoscopy is a noninvasive diagnostic tool that is currently being used for neoplastic skin lesions, several inflammatory and infectious diseases, and skin appendage disorders. As the clinical applications of dermoscopy beyond pigmented lesions are constantly increasing, the aim of this article is to provide an update on this topic. This comprehensive review substantiates how several diseases may show peculiar dermoscopy features so as to enhance the diagnosis and avoid (in selected cases) unnecessary histologic confirmation. In other cases, dermoscopy features may be shared with other conditions, with the advantage of narrowing down the differential diagnosis by ruling out those dermatoses with similar clinical aspect but different dermoscopic presentation.
