[PMID: 37598015 DOI: 10.1016/j.annder.2023.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 03/05/2023] [Accepted: 04/04/2023] [Indexed: 08/21/2023]
Abstract
BACKGROUND Although non-scarring alopecia (NSA) is a frequent clinical finding in patients with systemic lupus erythematosus (SLE), it has been poorly described in the literature. It is considered a nonspecific sign in the current classification of skin lesions of LE. The aim of this study was to give an updated overview of the spectrum of NSA in LE patients, with emphasis on the clinical significance thereof. METHOD We conducted a review of the English literature using the PubMed-Medline database using the keywords "Alopecia" + "Lupus erythematosus". Publications describing LE patients with NSA were included. RESULTS Data for 237 patients from 27 publications were analyzed. Ninety-one patients had diffuse NSA, 43 had patchy NSA, 83 had lupus hair, 3 had alopecia of dermal cutaneous LE, and 17 had alopecia of linear and annular lupus panniculitis of the scalp. Patients with diffuse/patchy NSA and lupus hair shared the following features: strong association with systemic activity of LE, subtle clinical/trichoscopic signs of inflammation, histological aspect consistent with lesions specific to cutaneous LE, high likelihood of response to SLE therapy, and absence of progression to scarring alopecia. Association with SLE was rare in patients with dermal cutaneous LE or linear and annular lupus panniculitis of the scalp, and skin-directed therapies were most often effective. One patient of each subtype progressed to scarring alopecia. DISCUSSION Diffuse/patchy NSA and lupus hair may represent a topographic variation of a single entity specific for LE. Prospective studies are warranted to further document the clinical significance of this manifestation.

Abstract
Plica neuropathica (PN), also known as plica polonica, trichoma, matting, felting, or bird's nest hair, is a common but rarely reported hair disorder. It is characterized by the abrupt onset of irreversible hair entanglement, forming a densely matted hair mass. PN has been associated with the use of ionic or herbal shampoos, vigorous hair care practice, self-neglect, systemic infection, parasitic infestation, immunosuppressive drugs, and psychiatric conditions. However, literature supporting the coexistence of PN in psychiatric disorders is scarce. PN may be one of the presenting symptoms observed by physicians. In some cases of psychiatric illness, patients consult more readily with non-mental health professionals than psychologists or psychiatrists. To highlight this issue, we herein report a case of PN in a 32-year-old woman with a 1-month history of being unable to detangle her hair. The patient initially visited the dermatology department and was subsequently diagnosed with schizophrenia following psychiatric consultation. After establishing the fundamental diagnosis apparently underlying the PN, psychiatric treatment with antipsychotic medication and dermatological treatment of the hair condition were instituted. There was an improvement in both at the four-week follow-up. This case history highlights a rare presentation of schizophrenia.

Abstract
The human skin is populated by a diverse pool of memory T cells, which can act rapidly in response to pathogens and cancer antigens. Tissue-resident memory T cells (TRM ) have been implicated in range of allergic, autoimmune and inflammatory skin diseases. Clonal expansion of cells with TRM properties is also known to contribute to cutaneous T-cell lymphoma. Here, we review the heterogeneous phenotypes, transcriptional programs, and effector functions of skin TRM . We summarize recent studies on TRM formation, longevity, plasticity, and retrograde migration and contextualize the findings to skin TRM and their role in maintaining skin homeostasis and altered functions in skin disease.

[PMID: 35469370 DOI: 10.1007/s11325-022-02618-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Revised: 03/09/2022] [Accepted: 04/15/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Sleep disturbances affect human health and contribute to several comorbidities. In men, androgenetic alopecia (AGA) is a common, non-scarring form of hair loss that affects a patient's self-esteem. There are limited data regarding the association between poor sleep quality and male AGA. We aimed to compare the prevalence of sleep abnormalities between male patients with AGA and controls to identify an association between the two conditions. METHODS A case-control study on patients with AGA and age-matched controls was conducted. Participants completed a standardized questionnaire that contained self-evaluated sleep measures, including Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale, and STOP-BANG questionnaire. Patients with AGA were classified into mild, moderate, and severe subgroups according to the Hamilton-Norwood classification for stratified analyses. Data between groups and among subgroups were compared. RESULTS Of 446 male participants, 223 (50%) were in the AGA group, and the remainder (50%) were in the control group. Multivariable logistic regression analysis revealed that hypertension (odds ratio [OR] = 1.90, 95% confidence interval [CI] = 1.16-3.11, p = 0.011) and STOP-BANG score ≥ 5 (OR = 2.05, 95%CI = 1.15-3.66, p = 0.015) were associated with AGA. For subgroup analyses, ordinal logistic regression model showed a significant association between severe AGA and three sleep profiles, namely total sleep time ≤ 6 h (OR = 2.16, 95%CI = 1.02-4.57, p = 0.044), PSQI > 5 (OR = 3.72, 95%CI = 1.42-9.72, p = 0.008), and STOP-BANG score ≥ 5 (OR = 3.01, 95%CI = 1.11-8.13, p = 0.030). CONCLUSION Our findings revealed an association between sleep disturbances and AGA, which may help guide appropriate management in these patients.

Abstract
Dermatosis neglecta (DN) is a frequently underrecognized skin disorder that occurs due to unconscious or conscious neglect of self-cleaning, causing the accumulation of keratin, sweat, sebum, and impurities. It is characterized by asymptomatic yellowish-to-brownish, waxy, adherent papules or plaques with cornflake-like scales that mimic several dermatological conditions. DN awareness is crucial for avoiding unnecessary invasive diagnostic procedures. Its lesions can be removed with some difficulty by ordinary cleansing and efficiently cleared with ethyl or isopropyl alcohol. Individuals with underlying physical or mental disabilities or psychiatric conditions are highly associated with DN. Nevertheless, supportive evidence for the coexistence of DN and psychological conditions is sparse, and most individuals with mental problems usually deny having psychiatric issues. Here, we present a case of DN resembling pemphigus foliaceus on the face with obsessive-compulsive disorder in a 16-years old male. The definitive diagnosis of DN in this patient was confirmed via histopathological examination. The lesions completely disappeared after appropriate facial cleansing and psychiatric management. DN may reveal underlying psychiatric disorders in patients.

Abstract
Background Patients with psoriasis are more likely than matched controls in the general population to have advanced liver fibrosis; however, our understanding of these patients is limited. There is currently no systematic evaluation of the prevalence and risk factors of liver fibrosis in psoriasis patients. Objective To evaluate the prevalence of psoriasis patients who are at high or low risk for advanced liver fibrosis and determine the risk factors for developing liver fibrosis. Methods Electronic searches were conducted using the PubMed, Embase, Scopus, and Cochrane Library databases from the dates of their inception till May 2022, using the PubMed, Embase, Scopus, and Cochrane Library databases. Any observational study describing the prevalence and/or risk factors for liver fibrosis in patients with psoriasis was included. Results Patients with psoriasis at high risk for advanced liver fibrosis had a pooled prevalence of 9.66% [95% confidence interval (CI): 6.92-12.75%, I 2 = 76.34%], whereas patients at low risk for advanced liver fibrosis had a pooled prevalence of 77.79% (95% CI: 73.23-82.05%, I 2 = 85.72%). Studies that recruited methotrexate (MTX)-naïve patients found a lower prevalence of advanced liver fibrosis (4.44, 95% CI: 1.17-9.22%, I 2 = 59.34%) than those that recruited MTX-user cohorts (12.25, 95% CI: 6.02-20.08%, I 2 = 82.34%). Age, sex, BMI, PASI score, psoriasis duration, MTX cumulative dose, and the prevalence of obesity, MTX users, diabetes mellitus, hypertension, dyslipidemia, and metabolic syndrome were not identified as sources of heterogeneity by meta-regression analysis. The pooled odds ratios for age >50 years, BMI > 30, diabetes mellitus, hypertension, dyslipidemia, and metabolic syndrome were 2.20 (95% CI: 1.42-3.40, I 2 = 0%), 3.67 (95% CI: 2.37-5.68, I 2 = 48.8%), 6.23 (95% CI: 4.39-8.84, I 2 = 42.4%), 2.82 (95% CI: 1.68-4.74, I 2 = 0%), 3.08 (95% CI: 1.90-4.98, I 2 = 0%), and 5.98 (95% CI: 3.63-9.83, I 2 = 17%), respectively. Conclusion Approximately 10% of the population with psoriasis is at high risk for advanced liver fibrosis, while 78% are at low risk. Patients over the age of 50 with obesity, diabetes, hypertension, dyslipidemia, and/or metabolic syndrome have an increased risk of developing liver fibrosis, necessitating monitoring.

Abstract
Rumpel-Leede phenomenon is a rarely reported condition with an unknown prevalence. It is characterized by the acute development of non-blanchable purpuric macules resulting from dermal capillary rupture caused by compressive forces. We report a case of Rumpel-Leede phenomenon in both feet following the application of pneumatic compression in a 49-year-old woman who underwent en bloc spondylectomy for a giant cell tumor of the spine. The condition appeared after the application of pneumatic compression on both legs for venous thromboembolism prophylaxis, and the lesions spontaneously resolved after discontinuation of compression. Currently, most cases are reported in patients with a history of diabetes mellitus, hypertension, or thrombocytopenia. We report a case of Rumpel-Leede phenomenon in a patient without underlying medical conditions. In our patient, capillary fragility combined with increased intracapillary pressure was hypothesized as the underlying mechanism.

Abstract
BackgroundSyphilitic alopecia (SA), which mimics other types of alopecia, is an uncommon manifestation of secondary syphilis. Trichoscopic features may facilitate its diagnosis. However, studies on SA and its trichoscopic characteristics remain limited.ObjectiveTo investigate the epidemiological, clinical, and trichoscopic findings and laboratory results, treatment, and outcomes of SA in Thai patients as well as to comprehensively summarize all trichoscopic features of SA through a systematic review.MethodsData on patients diagnosed with SA between December 2010 and December 2021 were obtained from their medical records and analyzed retrospectively. A systematic review of trichoscopic data, both from our institution and from studies registered in the PubMed, MEDLINE, and Embase databases, was conducted. A descriptive summarization was performed to comprehensively study the trichoscopic features of SA.ResultsOf the 205 patients with secondary syphilis, 23 patients with SA (symptomatic SA: 20, essential SA: 3) were included. The mean age was 27.6 ± 8.8 years, and male predominance was noted. The moth-eaten pattern was the most common SA presentation, and the parieto-occipital scalp was the most commonly affected area. All patients with SA achieved significant hair regrowth within 3 months of antibiotic therapy. Trichoscopic images were available for 20 patients with SA from our institute and were included in the systematic review. Fourteen articles provided information on 21 patients. Overall (N = 41), 26 (63.4%), 8 (19.5%), and 7 (17.1%) patients had moth-eaten alopecia, diffuse alopecia, and mixed alopecia, respectively. The most frequent trichoscopic finding was short regrowing hairs (78%), followed by decreased hair per follicular unit (75.6%), and empty follicles (51.2%). Unique features included flame hairs, bent tapering hairs, reddish-brown background, and brown rings around the perifollicular areas, each described in one case. However, the results were based only on case reports and small case series.ConclusionsGiven the progressively increasing frequency of SA, trichoscopic examination may be valuable when SA is suspected in patients with idiopathic alopecia; however, our findings are quite non-specific. The absence of exclamation mark hairs may help in the diagnosis of SA. Further comparative studies on other types of alopecia are required to determine the most useful diagnostic features.

Abstract
Introduction All types of lupus erythematosus (LE) may cause hair loss. Nonscarring alopecia was correlated with systemic LE, based on its high specificity. Discoid LE can also appear as nonscarring patches in early stages. Patchy alopecia LE-specific may also mimic alopecia areata (AA) - which can co-occur with LE. The distinction is fundamental to early diagnosis and effective treatment. This study aims to analyze clinical, epidemiological, trichoscopic, and histopathological features of patients with patchy LE-specific alopecia, nonscarring type, mimicking AA. Methods This is a multicentric retrospective study. We reviewed the medical records of patients with a confirmed diagnosis of LE mimicking AA. Results Ten patients were included (90% female) with a mean age of 45.9 years. Clinically, 60% showed erythema and 70% presented incomplete hair loss. The most common trichoscopic findings were interfollicular arborizing vessels (90%) and scattered brown discoloration (80%). On histopathology, perivascular inflammation (85.7%), peribulbar lymphocytes (85.7%), and dermal pigment incontinence (71.4%) were present in most cases. Discussion/Conclusion Trichoscopy was found as an essential first step for the patchy alopecia diagnosis, enabling to differentiate LE from AA. Putting it mildly, trichoscopy raises the suspicion that leads to a biopsy, increasing the diagnostic accuracy with better outcome for patients.

Abstract
Introduction Intramuscular corticosteroids (IMC) have gained popularity for the treatment of severe alopecia areata (AA) in recent years; however, evidence on their efficacy and safety is still limited. Objective To evaluate the efficacy, relapse rate, and tolerability of IMC in the treatment of AA, as well as factors associated with treatment outcomes. Methods Time-to-event analysis was performed on patients with severe, extensive, or rapidly progressive AA receiving IMC. The IMC regimen comprised triamcinolone acetonide 20–40 mg/mL injected every 4–6 weeks. The evaluated outcomes included initial (25% regrowth), significant (75% regrowth), and complete hair regrowth (100% regrowth). Relapse and adverse events were also noted. Factors associated with treatment outcomes and relapse were analyzed using the Cox proportional hazards model. Results A total of 101 patients were eligible for analysis. Significant hair regrowth was obtained in 80.2% of the patients (n = 81), in a median time of 3.4 months (95% confidence interval [CI] = 2.9–4.4). Complete hair regrowth was achieved in 48.5% of the subjects (n = 49), and relapse was observed in 47.5% (n = 48). Acneiform eruption was the most common adverse effect. Multivariable analysis revealed that nail involvement was a negative predictor of significant hair regrowth (adjusted hazard ratio [HR] = 0.04, 95% CI = 0.01–0.55; P = 0.015), whereas duration of AA longer than 6 months was associated with disease recurrence (adjusted HR = 4.02, 95% CI = 1.52–4.66; P = 0.005). Conclusion This study demonstrated the efficacy and safety of IMC in the treatment of severe or active AA; however, the relapse rate remained relatively high after discontinuation of the therapy. Nail involvement was a negative predictor of significant hair regrowth, while disease duration longer than 6 months predicted AA relapse.

Abstract
INTRODUCTION Scalp biopsy is a standard method for the definitive diagnosis of alopecia. The hair count parameters of each scalp area remain unclear. This study aimed to determine hair count values at different scalp locations from histopathology and to establish reference values for each part of the scalp. METHODS We obtained biopsy specimens from the frontal, vertex, temporoparietal, and occipital areas of the scalps of normal deceased subjects. All specimens were evaluated for the number of follicular units, hair counts, hair types, and stages of the hair cycle. RESULTS In total, 240 specimens were collected from 60 cadavers. Across all scalp sites, the temporoparietal area showed the lowest mean hair count, number of follicular units, terminal and vellus hairs, and terminal-to-vellus hair ratio. The average anagen-to-telogen hair ratio was comparable across all scalp sites. This study did not observe a significant association of hair parameters with gender differences or increasing age in all scalp areas. CONCLUSIONS The present study revealed the diversity of the hair index among different scalp areas and suggested that normal hair count values should be separately standardized on each scalp region. Our findings may provide useful reference values for the histopathological evaluation of hair disorders in Asians.

Abstract
Circle hair is a rare body-hair disorder of unknown etiology, typically characterized by perfectly or nearly perfectly coiled hair located below the cornified layer of the skin. Its main histopathological features are dilated hair-follicle infundibula and entrapped hair shafts. After its first description in 1963, there have only been a small number of reported cases, and its pathophysiology remains unclear. Herein, we report a case of an 80-year-old woman with skin lesions and abnormal hairs on both legs. We also propose a possible mechanism of her circle hairs: it may have occurred as an effect of her acquired ichthyosis secondary to her underlying multiple myeloma. There is no specific treatment for circle hairs, and reassurance that it is a harmless condition is sufficient. We prescribed a topical humectant and keratolytic agent to moisten the skin and lessen the hair entrapment, which resulted in clinical improvement. As the pathogenesis of the disease is unknown, further studies are warranted.

Abstract
Background: The occipital region of the scalp is generally accepted as an unaffected area of androgenetic alopecia (AGA) for both genders. However, evidence of AGA involving the occipital scalp has been demonstrated in women; meanwhile, it is unclear whether occipital involvement also occurs in men. Objective: We aimed to determine if there is occipital involvement in men with AGA. Methods: This case-control study compared hair counts of scalp biopsy specimens from the occipital region of 82 men with Hamilton-Norwood III-VII and 82 unaffected men. Results: The mean ages of men with AGA and controls were 40.1 ± 8.9 and 38.6 ± 10.5 years, respectively (P = 0.291). A significant decrease in total hair follicles, terminal hair follicles, follicular units and terminal to vellus (T:V) ratio, along with a significant increase in follicular stelae was indicated in the AGA group compared to controls (all P < 0.05). Subgroup analyses revealed that average counts of total hair follicles, terminal hair follicles and T:V ratios were also significantly lower in males with Hamilton-Norwood VI and VII than in controls (all P < 0.05). There were no correlations between increasing age and hair count parameters, but a significant negative association was found between total follicle numbers and disease duration (r = -0.23, P = 0.02). Conclusions: AGA can involve the occipital area of male patients with advanced disease. Therefore, the occiput of particular cases should not be used to determine reference data for normal scalp hair, and preoperative measurements of miniaturized hairs in the donor site are strongly recommended in all persons undergoing hair transplantation.

Abstract
BACKGROUND Increased rates of autoimmune diseases (ADs) have been reported in association with alopecia areata (AA); however, the risk factors for coexisting ADs in AA patients have been poorly investigated. OBJECTIVE To evaluate the prevalence and factors associated with AD comorbidities in patients with AA. METHODS This case-control study included patients diagnosed with AA between January 2000 and March 2020. Individuals with AA, both with and without concomitant ADs, were statistically compared. Variables significantly associated with coexisting ADs were identified using univariate and multivariate logistic regression analyses. Multinomial logistic regression analysis was performed to identify the specific risk factors for each concomitant AD. RESULTS Among the 615 patients with AA, comorbid ADs were found in 76 (12.4%). Autoimmune thyroid disease (AITD) exhibited the highest frequency (n = 42, 6.8%), followed by vitiligo (n = 15, 2.4%), and systemic lupus erythematosus (SLE) (n = 12, 2.0%). Logistic regression analyses revealed that female sex (odds ratio [OR] = 2.45, 95% confidence interval [CI] = 1.24-4.82; P = 0.011), nail abnormalities (OR = 2.49, 95% CI = 1.14-5.46; P = 0.023), and atopic diseases (OR = 1.98, 95% CI = 1.09-2.43; P < 0.001) were significantly associated with coexisting ADs. Regarding each concomitant AD, nail abnormalities were an associated factor for AITD (OR = 4.65, 95% CI = 1.96-7.24; P = 0.01), whereas coexisting atopic diseases were demonstrated as a predictor of vitiligo (OR = 2.48, 95% CI = 1.43-4.58; P = 0.02). Female sex (OR = 1.61, 95% CI = 1.18-4.27; P = 0.04) and family history of AD (OR = 1.85, 95% CI = 1.26-4.19; P = 0.03) were predictors of SLE. CONCLUSION This study suggests that female AA patients with nail abnormalities and atopic diseases have increased rates of AD comorbidities. A thorough review of systems for associated factors can help physicians screen for concomitant ADs.

Front Med (Lausanne) 2021; 8:683900. [PMID: 34422857 PMCID: PMC8377356 DOI: 10.3389/fmed.2021.683900] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 06/25/2021] [Indexed: 12/24/2022] Open
Abstract
Background: Nailfold capillaroscopy (NFC) is a valuable tool to detect microcirculation abnormalities in connective tissue diseases (CTDs). However, whether the universal serial bus (USB) digital microscopy used as onychoscopy is as effective as the videocapillaroscopy in determining the diagnostic and prognostic values of CTDs remains to be determined. Objective: This study aims to investigate NFC features of systemic lupus erythematosus (SLE), dermatomyositis (DM), and systemic sclerosis (SSc) patients and compare with normal controls as well as examine which feature could differentiate among CTDs. Furthermore, we aim to explore different capillaroscopic abnormalities and their association with disease activity. Methods: Nailfold images were taken from patients and healthy controls using a USB digital microscopy. Patterns on the capillary morphology, diameter, architecture, and density were recorded and compared. We further determined the NFC findings in SLE, DM, and SSc and corresponded to their respective disease activity scoring system. Results: A total of 245 participants, consisting of 54 SLE, 32 DM, and 51 SSc patients, as well as 108 controls, were enrolled. All capillaroscopic features, except for tortuous capillaries, were significantly more common in CTDs than healthy control (all p < 0.05). A multinomial logistic regression analysis revealed that bushy capillaries had significantly higher odds for both SLE and DM than SSc (OR: 4.10, 95% confidence interval (CI): 1.71-9.81, p = 0.002 and OR: 7.82, 95% CI, 2.86-21.38, p < 0.001, respectively). Elongated capillaries demonstrated significant odds for SLE compared with SSc (OR: 3.35, 95% CI: 1.005-11.20, p = 0.049), while prominent subpapillary plexus showed greater odds for SLE compared with both DM and SSc (OR: 2.75, 95% CI: 1.07-7.02, p = 0.03 and OR: 5.78, 95% CI: 2.29-14.58, p < 0.001, respectively). The presence of hemorrhage, enlarged capillaries, and the low-density index had significantly higher odds in favor of SSc than SLE. Bushy capillaries were the only pattern with a strong association for DM over SSc. The presence of enlarged capillaries indicated higher SLE severity, but no specific finding was related to DM or SSc skin scores. Conclusions: Nailfold capillaroscopic examination using a digital microscope is a valuable method for the diagnosis of SLE, DM, and SSc. Several morphologic patterns can help differentiate among CTDs; however, the prognostic significance of this method requires further investigations.

Abstract
Alopecia areata (AA) is an autoimmune disease of the hair follicles. It is characterized by a well-defined non-scarring alopecic patch or patches that may extend to the entire scalp or lead to total body hair loss. Due to its unpredictable clinical course, AA causes substantial psychological harm. Despite the high prevalence of this disease and extensive research, its exact pathomechanism is unclear, and current treatments have a high relapse rate that has deemed AA incurable. Over the past few decades, researchers have investigated multiple potential factors that may help alleviate its pathogenesis and provide effective treatment. Given its complex immunopathogenesis, AA is considered an autoimmune disease with multiple factors. This review gathers current evidence that emphasizes molecular mechanisms, possible causative etiologies, and targeted immunotherapies for AA. Understanding its underlying mechanisms may shed light on new strategies to effectively manage AA in the future.

Abstract
Lupus erythematosus (LE) is a chronic autoimmune condition with a wide spectrum of clinical presentations. Alopecias, both non-scarring and scarring, frequently occur in the context of LE and can assume several different patterns. Furthermore, alopecia occurring with LE may be considered LE-specific if LE-specific features are present on histology; otherwise, alopecia is considered non-LE-specific. Non-scarring alopecia is highly specific to systemic LE (SLE), and therefore has been regarded as a criterion for the diagnosis of SLE. Variants of cutaneous LE (CLE), including acute, subacute, and chronic forms, are also capable of causing hair loss, and chronic CLE is an important cause of primary cicatricial alopecia. Other types of hair loss not specific to LE, including telogen effluvium, alopecia areata, and anagen effluvium, may also occur in a patient with lupus. Lupus alopecia may be difficult to treat, particularly in cases that have progressed to scarring. The article summarizes the types of lupus alopecia and recent insight regarding their management. Data regarding the management of lupus alopecia are sparse and limited to case reports, and therefore, many studies including in this review report the efficacy of treatments on CLE as a broader entity. In general, for patients with non-scarring alopecia in SLE, management is aimed at controlling SLE activity with subsequent hair regrowth. Topical medications can be used to expedite recovery. Prompt treatment is crucial in the case of chronic CLE due to potential for scarring and irreversible damage. First-line therapies for CLE include topical corticosteroids and oral antimalarials, with or without oral corticosteroids as bridging therapy. Second and third-line systemic treatments for CLE include methotrexate, retinoids, dapsone, mycophenolate mofetil, and mycophenolate acid. Additional topical and systemic medications as well as physical modalities used for the treatment of lupus alopecia and CLE are discussed herein.

Abstract
BACKGROUND Age at disease onset may modulate systemic lupus erythematosus (SLE), but its relation to cutaneous/extracutaneous manifestation remains understudied. OBJECTIVE To compare the cutaneous, systemic features, laboratory characteristics, and disease severity between late- and adult-onset SLE patients. METHODS Analyses of the cutaneous, systemic involvement, laboratory investigations, SLE disease activity index 2000 (SLEDAI-2K), and disease damage were performed to compare between groups. RESULTS Of 1006 SLE patients, 740 and 226 had adult- (15-50 years) and late-onset (>50 years), respectively. Among 782 with cutaneous lupus erythematosus (CLE), acute CLE (ACLE) and chronic CLE (CCLE) were more common in the adult- and late-onset SLE, respectively (p = 0.001). Multivariable logistic regression analysis demonstrated that male patients and skin signs, including papulosquamous subacute CLE, discoid lupus erythematosus, and lupus profundus, were associated with late-onset SLE (all p < 0.05). Late-onset SLE had lower lupus-associated autoantibodies, and systemic involvement (all p < 0.05). ACLE, CCLE, mucosal lupus, alopecia, and non-specific lupus were related to higher disease activity in adult-onset SLE (all p < 0.001). There was no difference in the damage index between the two groups. CONCLUSIONS Late-onset SLE had a distinct disease expression with male predominance, milder disease activity, and lower systemic involvement. Cutaneous manifestations may hold prognostic values for SLE.

Abstract
Introduction Cutaneous manifestations are central to the primary diagnosis of systemic lupus erythematosus (SLE). However, information on the clinical, histopathologic, and direct immunofluorescence (DIF) features among subtypes of cutaneous lupus erythematosus (CLE), as well as longitudinal prospective observational study to evaluate the natural history and the progression to SLE, is lacking among Asians. Our objectives are to summarize the differences in the clinical, histopathologic, and DIF characteristics and serological profiles between various subtypes of CLE, and to provide its natural history and the association with disease activity in our Asian population. Methods A prospective observational study on CLE patients was performed between May 2016 and May 2020. Patients underwent full physical/dermatologic examination, skin biopsy for histology, and DIF. Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) scores and laboratory data were evaluated. Time schedule and characteristics for resolution and/or the disease progression to SLE were recorded in subsequent follow-ups. Results Of 101 biopsy-proven CLE patients, 25 had acute CLE (ACLE), 8 had subacute CLE (SCLE), 39 had chronic CLE (CCLE) only, 22 had CCLE with SLE, and 7 had LE-nonspecific cutaneous lesions only. Patients with exclusive CLE showed lower female preponderance, serological abnormalities, and correlation to systemic disease. However, when CLE was accompanied with any LE-nonspecific cutaneous manifestations, they were associated with high antinuclear antibody (ANA) titer, renal, hematologic, joint involvement, and greater SLEDAI score. Of 207 biopsy sections, SCLE/CCLE regardless of systemic involvement showed significantly higher percentage of superficial/deep perivascular and perieccrine infiltration than ACLE. On DIF, deposition of multiple immunoreactants was associated with higher systemic disease. Approximately 10% of CLE-only patients later developed SLE but had mild systemic involvement. Conclusion Our findings support that each CLE subtype has a diverse and unique character. Comprehensive understanding of the differences among CLE subtypes is important for achieving the correct diagnosis and providing appropriate disease monitoring and management.

Abstract
Linear and annular lupus panniculitis of the scalp (LALPS) is a unique subset of lupus panniculitis, which results in non-scarring alopecia along the Blaschko line of the scalp in an otherwise healthy young patient. Numerous cases have been reported around the world, but data on their trichoscopic findings and correlations with the underlying pathology is sparse. We hereby present a case of 23-year-old male with LALPS and further describe his trichoscopic findings as well as their correlations with histopathological features.
