Abstract
Hair disorders, including central centrifugal cicatricial alopecia (CCCA), traction alopecia (TA), and acquired trichorrhexis nodosa (ATN), commonly occur in individuals with curly textured hair. Curly textured hair in individuals of African descent has unique properties and can present diagnostic and therapeutic challenges. CCCA has been linked to uterine leiomyoma and type 2 diabetes mellitus, as well as fibroproliferation. TA often presents with a fringe sign and can arise from high-tension hairstyles presumed to be protective. Trichoscopy is useful in establishing a diagnosis; perifollicular halos are more commonly seen than perifollicular erythema or scale in CCCA. In TA, miniaturized follicles, hair casts, and "flambeau sign" can be seen. Hairstyling practices likely contribute to TA and ATN; however, the data are mixed on the role of chemical relaxers and heat styling in CCCA. Unique considerations in the presentation of frontal fibrosing alopecia in curly textured hair have also been published recently. This review provides a comprehensive, up-to-date summary of these disorders with an emphasis on their unique properties, as well as considerations in hair care for curly textured hair.

Int J Dermatol 2024; 63:23-31. [PMID: 37950461 DOI: 10.1111/ijd.16895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 10/20/2023] [Accepted: 10/22/2023] [Indexed: 11/12/2023]
Abstract
Androgenetic alopecia (AGA) is the most prevalent type of hair loss in women and men. Recently, a European consensus group published guidelines for the diagnostic evaluation of AGA in men, women, and adolescents. This S1 guideline presents expert opinion-based recommendations for gender-dependent steps in the diagnostic procedure, which can easily be implemented in the daily clinical routine. For diagnosing AGA, detailed anamnesis and objective learning are not enough because there are several conditions mimicking this disease. Trichoscopy can be considered an important, non-invasive tool for diagnosing hair and scalp disorders that may have similar clinical signs to AGA.

Abstract
Trichoscopy is currently regarded as an essential part of the hair loss consultation. It allows visualization of morphologic structures that are not obvious to the naked eye, including peri- and interfollicular skin surface abnormalities and changes to hair shaft thickness and shape. In this paper, we aim to discuss current knowledge on trichoscopy of the most common forms of scarring and nonscarring alopecias.

Abstract
African hair shaft and pigmented scalp have unique features that challenge diagnosis in scarring alopecia. In addition, Black patients may associate 2 or more types of hair disorders. Therefore, it is imperative to understand their findings thoroughly to establish a good diagnosis. Differential diagnosis on the frontal scalp includes traction alopecia and frontal fibrosing alopecia. Disorders such as central centrifugal cicatricial alopecia, fibrosing alopecia in a pattern distribution, discoid lupus erythematosus, and lichen planopilaris usually affect the middle scalp. Folliculitis decalvans, dissecting cellulitis, and acne keloidalis nuchae are the main differential diagnosis of the posterior scalp.

Abstract
This review describes and highlights differences in clinical presentations of cutaneous lymphomas (CLs), particularly in darker skin types, i.e., Skin of Color (SOC). We illustrate differences in clinical features on physical exam that can be a diagnostic challenge and suggest ways to recognize and identify these conditions at an early stage through a high level of suspicion. The review includes a summary of the epidemiology of various CLs, specifically highlighting the presentation and incidence in African American/Black patients, where the data are available. We also include a discussion of adult HTLV-1-associated T-cell leukemia/lymphoma (ATLL) which, although a systemic T-cell lymphoma, may present with skin manifestations and mimic MF, other CTCL subtypes, or other inflammatory dermatoses. Finally, this review highlights the possible use of imaging modalities, such as dermoscopy and reflectance-confocal microscopy, in diagnosing and recognizing cutaneous lymphomas in patients with darker skin types.

Abstract
Central centrifugal cicatricial alopecia (CCCA) is a form of scarring alopecia that predominantly affects middle-aged women of African descent. Recent data suggest a multifactorial etiology of CCCA that is influenced by environmental and genetic factors. Emerging evidence regarding the genetic basis of the condition may elucidate new therapies. While topical and intralesional steroids and tetracycline antibiotics are the mainstay of treatment, refractory cases may be considered for hair transplantation. Emerging therapies using platelet-rich plasma, botanical formulas, and cosmetic procedures have shown promising results for the future management of CCA. As recent notable advances in CCCA have been achieved, this review provides an update on the epidemiology, pathophysiology, and management of CCCA.

Abstract
BACKGROUND Frontal fibrosing alopecia (FFA) is a scarring alopecia that affects the frontotemporal hairline. Clinically, it may develop with cutaneous hypopigmentation of the affected areas, which has been associated with a reduction in the epidermal melanocyte count. In trichoscopy, peripilar white halos can be observed, which have been associated with fibrosis in other scarring alopecias. OBJECTIVE To evaluate the trichoscopic, histopathological and immunohistochemical characteristics of the peripilar white halos in FFA patients. MATERIALS AND METHODS We conducted a descriptive cross-sectional study that included 12 patients with FFA presenting peripilar white halos. Two 2-mm punch trichoscopy-guided biopsies were performed in all patients, one fragment for vertical section and another for horizontal section. The vertical sections were stained with Fontana-Mason and Melan-A. RESULTS On trichoscopic examination, peripilar white halos ≤ 1 mm in size were observed on the affected scalp. In vertical sections, a reduction in basal melanin pigmentation and a decrease in the melanocyte count in the upper segment of the hair follicle were observed with Fontana-Masson staining and Melan-A immunostaining, respectively. LIMITATIONS The small sample size and absence of a control group. CONCLUSION This study shows follicular melanocyte involvement in FFA, and this finding may be associated with the peripilar white halos observed in trichoscopy.

Abstract
Primary cicatricial alopecia (PCA) is a form of alopecia in which inflammatory cells target follicles, including the bulge region containing follicular stem cells, leading to permanent alopecia. New classifications of PCA subtypes have recently been proposed, including those that account for novel trichoscopic and histopathological features of PCA, enabling greater precision in the evaluation and diagnosis of this condition. Nonetheless, diagnosis remains challenging clinically and histopathologically because the etiology of PCA is multifactorial. Inconsistent use of terminology, overlapping disease concepts, and changes in the clinical or histopathological severity of inflammation in the disease course in the same patient also make diagnosis quite challenging. The present study comprehensively reviews recent progress in diagnostic techniques, including the use of clinical, trichoscopic, and histopathological features, in evaluating each PCA subtype, containing overlapping and specific features. Elucidating the features of PCA, including those that are common to multiple subtypes as well as specific to each in both early and advanced-stage lesions, is important for accurate diagnosis. Improving the evaluation and treatment of this disease depends on having a broader clinical understanding that takes into account not only the features of the disease at a given point in time, but also the changes that occur during the entire disease course.

Abstract
Trichoscopy represents a non-invasive diagnostic modality widely used in daily practice. Despite the common perception that this technique has been fairly established, some key issues remain to be addressed. Complexity and inconsistency in terminology in past literature are likely to confuse investigators when they are recording, reporting, and retrieving the findings. In addition, a diagnostic algorithm adopting sufficiently integrated and updated findings is not readily available. By adopting a systematic review approach, this review attempted to redefine major trichoscopic findings and integrate their synonyms individually into the most frequently used terms besides identifying and discussing terms which potentially cause confusion. The findings are categorized into five subgroups: hair shaft, follicular, perifollicular, scalp findings, and hair distribution pattern abnormalities. The calculation of sensitivities and positive predictive values of such redefined findings was conducted by reviewing the descriptions in the past literature on major hair diseases, including alopecia areata, androgenetic alopecia/female pattern hair loss, telogen effluvium, trichotillomania, lichen planopilaris, frontal fibrosing alopecia, central centrifugal cicatricial alopecia, discoid lupus erythematosus, folliculitis decalvans, tinea capitis, and dissecting cellulitis, to confirm the diagnostically meaningful findings for representative diseases. This attempt redefined, for instance, yellow dots, short vellus hairs, exclamation mark hairs, black dots, and broken hairs as the findings of diagnostic significance for alopecia areata and hair diameter diversity, peripilar sign, and focal atrichia for androgenetic alopecia/female pattern hair loss. An updated diagnostic flowchart is proposed with the instructions to maximize its usefulness. Current limitations and future perspectives of trichoscopy as well as other emerging non-invasive diagnostic modalities for hair diseases are also discussed.

Abstract
Dermatology for the pediatric skin of color population is the application of dermatology to the genetically diverse and distinctive segment of the pediatric population that includes children of non-White racial and ethnic groups with increased pigmentation including individuals of Asian, LatinX, African, Native American, Pacific Island descent, Indigenous Peoples, among others, with overlap in particular individuals, and mixtures thereof. Treating children of color is a unique skill set within the field of pediatric dermatology, requiring knowledge and sensitivity. The discipline of pediatric skin of color can be challenging. Difficulty in diagnosis of common conditions stems from underlying pigmentation, variations in common hairstyling practices, and differences in demographics of cutaneous disease, whereas some conditions are more common in children of color, other conditions have nuances in clinical appearance and/or therapeutics with regard to skin color. This article is the first in a series of two articles looking at recently published skin-related issues of high concern in children of color. Conditions reviewed in Part 1 include (1) hairstyling hair-related concerns (traction alopecia, central centrifugal cicatricial alopecia, endocrine disruption), (2) autoimmune concerns (cutaneous lupus, vitiligo), and (3) infections (tinea capitis, progressive macular hypomelanosis).

Abstract
Fibrosing alopecia in a pattern distribution (FAPD) is a unique entity which presents clinicopathological characteristics of both male/female pattern androgenetic alopecia (AGA) and lichen planopilaris (LPP). This entity was first reported in 2000 and its criteria was recently proposed. Etiopathogenesis of FAPD has been speculated to be immunological destruction involving miniaturized hair follicles but still remains elusive. To date, few Asian FAPD cases have been reported in the literature. In this study, Japanese FAPD cases were identified based on the aforementioned criteria and analyzed to delineate clinicopathological characteristics. By retrospectively revisiting medical records and clinical photographs, 24 Japanese cases comprising 17 women and seven men were diagnosed as FAPD. All male patients had disease onset by their early 30s, whereas most female patients had developed the condition in middle age or later. Their initial diagnoses prior to the diagnostic confirmation of FAPD were mostly LPP. Based on the clinical phenotypes, the cases were categorized into AGA and LPP types. These subtypes were characterized by foremost trichoscopic and histopathological findings of AGA or LPP, respectively. Unlike previously reported cases, our patients tended to manifest hair loss in both vertex and frontal to mid-scalp with minimal regression of anterior hairline, manifesting unique "parachute" pattern, which has been reported as a representative characteristic of East Asian AGA in the literature. Anti-inflammatory therapies seemed to be effective to deter hair loss but insufficient to achieve improvement. Further accumulation of the cases is necessary; however, these findings may provide additional pathophysiological insights into FAPD and highlight uniqueness of the etiology and clinical phenotype of Japanese FAPD putatively influenced by racial predispositions.

Abstract
Lichen planopilaris (LPP) is characterized by chronic cicatricial alopecia that is lymphocytic in nature. The underlying pathophysiology of LPP is not well understood. Failure of therapeutic management occurs quite often resulting in significant psychosocial stress on the patient when they are unable to prevent further hair loss or reverse it. Although the occurrence of LPP is rare, it is especially seldom observed in the pediatric population. Herein, we discuss a case of a nine-year-old child who was recently diagnosed with LPP.

Abstract
BACKGROUND Fibrosing alopecia in a pattern distribution (FAPD) is a primary cicatricial alopecia considered a subtype of lichen planopilaris (LPP). OBJECTIVE The clinical and histopathological features, and treatment response of 24 female patients with FAPD were evaluated. METHODS Demographic, clinical, histopathological and treatment data of patients with FAPD were retrospectively collected. RESULTS Twenty-four women were included (mean age 60.7 years). The mean Lichen Planopilaris Activity Index score was 1.50, and the median Sinclair grade was 3. Twelve patients had diffuse alopecia in the centroparietal region, four had frontal accentuation and eight had vertex accentuation of hair loss. Eight had associated loss of facial hair. Predominant trichoscopic features included hair shaft diameter variability (100%), perifollicular erythema and/or scaling (95%) and loss of follicular ostia (95%). Histopathological examination revealed features of scarring alopecia with interface changes in follicular epithelia mainly targeting terminal and intermediate hairs, and less frequently, vellus hairs. Treatment with hair growth-promoting, anti-inflammatory and anti-androgen agents arrested disease progression in 14 patients and resulted in hair regrowth in two patients. Six patients had progression of their hair loss in spite of treatment. LIMITATIONS Referral bias to a specialist hair clinic, retrospective design and small sample size. CONCLUSIONS We present clinicopathological features of FAPD which can aid in the diagnosis of this insidious scarring alopecia. Our findings suggest a more favourable outcome if treatment is initiated in early stages of the disease.

Abstract
Central centrifugal cicatricial alopecia (CCCA) is the most common form of primary scarring alopecia diagnosed in women of African descent. Although the etiology was originally attributed exclusively to hairstyling practices common among women of African descent, more recent research on CCCA supports the concept that there are several contributing factors, including variants in gene expression, hair grooming practices that increase fragility on the hair follicle, and associations with other systemic conditions. Treatment of CCCA involves a combination of patient counseling and education on alternative hairstyles, medical therapies, and procedural methods when necessary.

Abstract
Trichoscopy is an emerging technique for the evaluation of various hair and scalp disorders including primary cicatricial alopecias (PCAs). Early diagnosis of PCAs can lead to effective management and trichoscopy could be a useful aid during this process. Multiple studies have reported the trichoscopic features of PCAs, however, a focused review evaluating these disorders with their trichoscopic features is lacking. With the objective of evaluating the trichoscopic findings reported in the literature for various PCAs, we conducted a systematic literature search in PubMed and Embase. The search yielded 310 studies in a total of which 54 studies were included in our review. Majority of these studies originated from the Caucasian or Asian population. Through this review, we provide an overview of the frequent and specific trichoscopic findings in different PCAs with their clinical significance where applicable based on the current knowledge and identify the areas for future research.

Abstract
Frontal fibrosing alopecia (FFA) is characterized by progressive band-like scarring alopecia involving the frontotemporal hairline and limbs and irreversible alopecia of the eyebrows. Two opposite types of pigmentary alterations have been reported in FFA: hyper- and hypopigmentation. Here, we report a 57-year-old Hispanic female with FFA who presented with peripilar hypopigmentation and idiopathic guttate hypomelanosis on the upper extremities. To our knowledge, this is the first report of peripilar white halos in a patient of a White Hispanic origin. Upon review of other previous publications on trichoscopy of FFA, this pattern has not been detected. The common pattern of focal absence of melanocytes and melanin in both is another confirmation that FFA is associated with pigmentation abnormalities.

Abstract
Background Fibrosing alopecia in a pattern distribution (FAPD) has only been described in Caucasian patients, and it is not clear whether it can develop in dark-skin ethnicities. Materials and Methods Sixteen Brazilian female patients, 12 of African descent and 4 Hispanic, with progressive scarring alopecia in a pattern distribution were analyzed. Results Dermatoscopic features showed perifollicular erythema and scaling (14/16), hair fiber diameter diversity (16/16), loss of follicular ostia (16/16), and follicular keratosis (3/16). Late stages showed a honeycomb pigmented network (12/16), a hyperpigmented perifollicular halo (12/16), and small white patches (12/16). Histopathological features showed lichenoid perifollicular infiltrate (14/16), follicular miniaturization (16/16), concentric fibrosis (16/16), perifollicular lymphocytic infiltrate (16/16), and vellus hair involvement (10/16). Premature desquamation of the inner root sheath was found in 11 patients. Conclusions The concomitant findings of cicatricial pattern hair loss (with or without the recess of the front hair line), hair fiber diversity, perifollicular erythema and scaling, a whitish perifollicular halo, and histological findings of androgenetic alopecia, with vacuolar interface alteration of the upper portion of the follicular epithelium, are the main key features to suggest the diagnosis of FAPD. FAPD is a possible diagnosis in patients of color with cicatricial pattern hair loss. Clinical, dermatoscopic, and histopathological examination allow a proper final differential diagnosis.

Abstract
Hair loss is common in women of color, and is associated with significant psychosocial complaints. Early clinical recognition and prompt initiation of intervention with medical treatment is critical to halt the disease process. In this article, we review the clinical presentations of nonscarring and scarring alopecias in women of color, use of dermoscopy for early recognition of the disease process, and medical, procedural, and surgical interventions. In conditions that result in scarring alopecia, such as late-stage traction, frontal fibrosing, or central centrifugal cicatricial alopecia, patients may benefit from procedural interventions, such as hair transplantation, platelet rich plasma injections, low-level laser therapy, or scalp therapy.

Abstract
BACKGROUND The application of heat, used to straighten the typically coiled hair, has long been hypothesized to play a role in the etiologic factor for central centrifugal cicatricial alopecia (CCCA). The aim of this study was to evaluate the effect of thermal hair straightening on hair loss pattern in Asian women exist. MATERIALS AND METHODS Thirty-five patients with hair loss who have been using hair straightening devices and 25 patients with telogen effluvium were enrolled in this prospective study. Laboratory analysis and dermatoscopic findings were used to compare these groups. RESULTS The peripilar white halo around hairs, peripilar dark/gray halo around follicular orifices, the predominance of a single hair perifollicular unit (FU), hair diameter diversity, the thin miniaturized hair, interfollicular pinpoint white dots, and white patches were statistically higher in hair straightener group (P < 0.001). White patches of the scalp increased by the time of the application of these devices (P < 0.01). White patches of vertex region were significantly higher than the midfrontal region (P < 0.01). CONCLUSION The common side effects of thermal hot comb strengtheners' were summarized as damage to the hair shaft; decreasing in the brightness of the hair, burns, and scars on the scalp; and lastly CCCA-like hair loss.

Abstract
Central centrifugal cicatricial alopecia (CCCA) is included among the primary lymphocytic cicatricial alopecias. The current nomenclature of CCCA suggested by the North American Hair Research Society refers to the traditional clinical presentation pattern of this type of alopecia, which begins in the central area of the scalp and has a progressive and symmetric centrifuge evolution. However, some exceptions should be highlighted, and a new clinical variety of CCCA presenting with patches of hair loss affecting the lateral and posterior scalp has been recently described. Here, we report a new case of CCCA presenting with a patchy pattern. In addition to the fact that this new patchy presentation of CCCA is not contemplated in the current terminology, it has a difficult differential diagnosis with other alopecias that have patches as their presentation. In these cases, both the trichoscopy and the histopathology are indispensable for diagnosis that will allow a targeted treatment and avoid an unfortunate prognosis.

Abstract
Several patterns of hair loss can occur in lupus erythematosus (LE). Alopecias which show histological characteristics of LE are LE-specific, and include discoid LE (DLE), diffuse or patchy hair loss in acute LE, subacute cutaneous LE, and rarely tumid LE. Lupus hair in SLE is a poorly characterised entity and may be a form of telogen effluvium. Alopecia areata can coexist with LE and may mimic DLE. Non-lupus alopecias such as telogen effluvium and anagen effluvium have a myriad of causes which include disease flares, drugs and stress in the setting of LE. The latest validated Systemic Lupus International Collaborating Clinics classification criteria for SLE includes non-scarring alopecia as a criterion; therefore, recognising the aetiology of hair loss in the setting of LE is crucial in classifying a patient to have systemic disease.

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.

Abstract
Trichoscopy is a noninvasive visualization tool used to more accurately diagnose hair and scalp disorders. Alopecia areata (AA) in the patient of African descent can mimic the early signs of central centrifugal cicatricial alopecia (CCCA), especially if the initial presentation of hair loss occurs on the central scalp. Two African-American women presented with singular round-ovoid patches of decreased hair loss on the central scalp. Given the clinical presentation, CCCA was the working diagnosis. However, using dermoscopy, the patients were found to have exclamation hairs and short broken hairs on a background of honeycomb-like pigmented network and regular pinpoint white dots consistent with AA. The diagnosis was confirmed on biopsy. We demonstrate the role of dermoscopy for diagnosing AA in the patient of African descent.

Abstract
BACKGROUND Traction alopecia refers to (often permanent) hair loss caused by prolonged physical damage. No study has yet described the unique trichoscopic findings of the condition. We describe the trichoscopic findings of traction alopecia and its relationships with the duration of traction. METHODS We studied 25 patients who were clinically diagnosed with traction alopecia. The patients were divided into two groups in terms of traction duration. Trichoscopy was performed at a minimum of two scalp locations in each patient. RESULTS Reduction in hair density, hair diameter diversity, empty follicles, and vellus hairs were observed in all patients. In addition, the following were observed: loss of follicular openings in 19 (76%) patients, yellow dots and broken hairs in 17 (68%), black dots in 12 (48%), hair casts in 7 (28%), circular hairs in 5 (20%), and arborizing red lines in 3 (12%). The trichoscopic findings varied with the duration of traction. CONCLUSIONS Traction alopecia is a chronic condition that is difficult to treat. Trichoscopy can be used for diagnosis. Our study is the first to identify the early and late trichoscopic features of traction alopecia. The limitation of the study is the lack of histologic diagnosis.

Abstract
Skin of color comprises a diverse and expanding population of individuals. In particular, women of color represent an increasing subset of patients who frequently seek dermatologic care. Acne, melasma, and alopecia are among the most common skin disorders seen in this patient population. Understanding the differences in the basic science of skin and hair is imperative in addressing their unique needs. Despite the paucity of conclusive data on racial and ethnic differences in skin of color, certain biologic differences do exist, which affect the disease presentations of several cutaneous disorders in pigmented skin. While the overall pathogenesis and treatments for acne in women of color are similar to Caucasian men and women, individuals with darker skin types present more frequently with dyschromias from acne, which can be difficult to manage. Melasma is an acquired pigmentary disorder seen commonly in women with darker skin types and is strongly associated with ultraviolet (UV) radiation, genetic factors, and hormonal influences. Lastly, certain hair care practices and hairstyles are unique among women of African descent, which may contribute to specific types of hair loss seen in this population, such as traction alopecia, trichorrhexis nodosa and central centrifugal cicatricial alopecia (CCCA).

Abstract
Frontal fibrosing alopecia (FFA) and fibrosing alopecia in a pattern distribution (FAPD) as originally reported by Kossard in 1994 and by Zinkernagel and Trüeb in 2000, respectively, represent two distinct patterns of cicatricial pattern hair loss. Both share a patterned distribution and histological evidence of a lichenoid follicular inflammation with fibrosis. FFA is characterized by a marginal alopecia along the frontotemporal hairline, and FAPD by a progressive alopecia of the centroparietal scalp. Since the original reports, evidence has accumulated that there exists considerable clinical overlap among FFA, FAPD, and lichen planopilaris, with coexistence of features of the three conditions within the same individual. Moreover, familial cases of FFA have been reported, pointing to a possible genetic background to the condition. Our observation of familial occurrence of FFA and FAPD in daughter and mother, respectively, further underscore a nosologic relationship between the two conditions with respect to both an androgenetic background and the (lichenoid) inflammatory reaction pattern.

Abstract
Central centrifugal cicatricial alopecia (CCCA) is the most common scarring alopecia among African American women. Data about epidemiology, etiology, genetic inheritance, and management are scarce and come from individual reports or small series. CCCA has been associated with hot combing and traumatic hair styling for years; however, studies fail to confirm it as the sole etiologic factor. It has been shown in a small series that CCCA can be inherited in an autosomal dominant fashion, with a partial penetrance and a strong modifying effect of hairstyling and sex. CCCA presents clinically as a central area of progressive irreversible hair loss that expands to the periphery. A patchy form has also been described. Dermoscopy is helpful to identify the optimal site for the biopsy, which establishes the diagnosis. Well-designed randomized controlled trials are needed to discover the optimal management. At this point, patients are advised to avoid traction and chemical treatments; topical and intralesional steroids, calcineurin inhibitors, and minoxidil can be helpful in halting the progression.

Abstract
BACKGROUND There are limited data on the validity of dermatoscopy in primary cicatricial alopecias (PCAs) and its subtypes, including lichen planopilaris and discoid lupus erythematosus. Trichoscopic features of PCAs, their prevalence, and validity were evaluated in this study. METHODS One hundred patients with PCA underwent dermatoscopy. Biopsy specimens were obtained after the site was marked with a dermatoscope. The control group comprised 100 patients with non-cicatricial alopecia and 100 normal individuals. Finally, the prevalence, sensitivity, and specificity of trichoscopic features were evaluated using SPSS and Stata software. RESULTS The absence of follicular opening, perifollicular scale, and presence of one scarring pattern or white patch were sensitive and specific patterns in the trichoscopy of PCAs. The presence of tortuous branching vessels and follicular keratotic plugging was 100% specific for a diagnosis of discoid lupus erythematosus. CONCLUSIONS Some trichoscopic features can help a dermatologist to differentiate between non-cicatricial alopecia and PCA. Moreover, a group of dermatoscopic features can be helpful in the diagnosis of PCA subtypes.

Abstract
BACKGROUND 'Flame hairs' is a trichoscopic feature described as hair residue from pulling anagen hairs in trichotillomania. OBJECTIVE To detect whether flame hairs are present in other hair loss disorders. METHODS We retrospectively, independently and blindly reviewed the trichoscopic images of 454 consecutive patients with alopecia areata (99 cases), trichotillomania (n = 20), acute chemotherapy-induced alopecia (n = 6), acute radiotherapy-induced alopecia (n = 2), tinea capitis (n = 13), lichen planopilaris (n = 33), frontal fibrosing alopecia (n = 60), discoid lupus erythematosus (n = 30), dissecting cellulitis (n = 11), central centrifugal cicatricial alopecia (n = 94) and traction alopecia (n = 86) for the presence of flame hairs. We prospectively obtained trichoscopy-guided scalp biopsies from flame hairs in trichotillomania, alopecia areata, traction alopecia and central centrifugal cicatricial alopecia (1 case each). RESULTS Flame hairs were detected in 100% of the acute chemotherapy- and radiotherapy-induced alopecias, where they were the predominant hair abnormality. They were also found in trichotillomania (55%), alopecia areata (21%), traction alopecia (4%) and central centrifugal cicatricial alopecia (3%). On pathology, they corresponded to distorted hair shafts. CONCLUSION The flame hair is a type of broken hair which can be seen in various hair loss disorders. It results from traumatic pulling of anagen hairs or from anagen arrest due to inflammation or drugs. © 2015 S. Karger AG, Basel.

Abstract
BACKGROUND Central centrifugal cicatricial alopecia (CCCA) is the most common cause of scarring alopecia among women of African descent which affects the central scalp and spreads centrifugally but spares the lateral and posterior scalp. OBJECTIVES The objective of this study is to report on a new clinical variety of CCCA presenting with patchy alopecia involving the lateral and posterior scalp in addition to the central scalp. MATERIALS AND METHODS We reviewed the medical records and the clinical, dermatoscopic and pathologic data of 14 African-American women with CCCA presenting with patchy alopecia. RESULTS Two patients had individual well-delineated patches of hair loss, and 12 patients had multiple irregular patches of hair loss. In all cases, the alopecia affected the lateral and posterior scalp in addition to the central scalp. Four patients had a history of traumatic hairstyles, and 10 patients were also affected by marginal traction alopecia. On dermatoscopy, the patches showed peripilar white-gray halos and broken hairs. The pathologic diagnosis of CCCA was based on the following features: follicular dropout, absent or only focally preserved sebaceous glands, premature desquamation of the inner root sheath and perifollicular fibrosis with mild inflammatory infiltrate. CONCLUSION CCCA can present with patches of hair loss involving the parietal and posterior scalp in addition to the central scalp. Without dermatoscopy and pathology, this variety can be easily misdiagnosed as traction alopecia.
