Abstract
An 11-year-old male Golden Retriever was presented for consultation due to a chronic progressive lesion on the nose that had started a year before. The majority of the nasal mucosa was affected, with the disruption of the normal architecture, pigment atrophy and abundant peeling on the rostral plane. Histopathology revealed a band of lichenoid infiltrate at the interface and vacuolation of the cells in the basal layer consistent with a diagnosis of canine discoid lupus erythematosus.

Abstract
Discoid lupus erythematosus (DLE) is a common autoimmune skin disease in dogs. Conventional treatments, such as corticosteroids, can be effective but often have side effects. This case report presents a successful use of cannabinoid therapy (CT) in a dog with DLE resistant to conventional treatment. A 2-year-old mixed-breed dog with a history of DLE presented with worsening lesions despite treatment with corticosteroids and other medications. Liver enzymes levels were elevated, indicating corticosteroid-induced side effects. CT with a CBD-rich full spectrum Cannabis oil was initiated. The dosage was gradually adjusted until the minimum effective dose was found. Within a few weeks of starting CT, the dog showed significant improvement in skin lesions and in liver enzymes levels. After 1 year, the dog remains clinically stable on a low dose of full-spectrum CBD-rich oil. No evidence of DLE recurrence was observed. This case suggests that CT may be a viable alternative or complementary therapy for DLE in dogs, particularly for those experiencing adverse effects from conventional treatments. Further research is warranted to confirm the efficacy and safety of CT for DLE management in dogs.

Abstract
Discoid lupus erythematosus (DLE) is a disfigurement disease. The atrophic scar and hair loss of this disease are followed by cosmetic defects and profoundly impact psychological health. Concentrated growth factor (CGF) has been widely adopted in medical cosmetology. Here we report a 36-year-old female systemic lupus erythematosus patient with a 5-year history of alopecia in DLE, who was recommended for CGF therapy and experienced hair regrowth. We suggest that CGF may be an effective cosmetic treatment for DLE.

Abstract
Lupus erythematosus is an autoimmune disorder with varied clinical features. Discoid Lupus Erythematosus (DLE) presents as erythematous, raised plaques. The patients might present with photosensitivity, arthralgia, and nail changes. However, dermoscopy, clinical features, and laboratory markers like high titers of Antinuclear antibodies (ANA) help in clenching the diagnosis. We report a patient in her mid-60s presented with non-healing ulcers oozing pus discharge associated with pain and joint stiffness. Thus, a series of investigations, treatment modifications, and the healing progression of the lesions highlight the importance of retrospective diagnosis.

Abstract
INTRODUCTION Dermoscopic findings are used to diagnose and evaluate disease activity in patients with cutaneous lupus erythematosus (CLE). OBJECTIVES This study aimed to characterize the dermoscopic features of discoid LE (DLE) and LE tumidus (LET) by lesion duration and CLE Disease Area and Severity Index (CLASI) scores and to examine the dermoscopic findings of lesions in different locations in DLE patients. METHODS Dermoscopic findings (follicular features, perifollicular surface, interfollicular features, and vessel pattern) were assessed and lesion duration (≤12 and >12 months) and CLASI scores (grouped as mild or moderate) were calculated. DLE lesion locations were categorized as, non-scalp, scalp and lip. RESULTS Forty-eight dermoscopic images from 35 DLE and 4 LET patients were analyzed. The most common dermoscopic findings in non-scalp DLE were follicular keratotic plugs (82.8%) and white scales (69%). In scalp DLE (n=9), the most common findings were absent follicular openings (77.8%), white structureless areas (77.8%), and perifollicular scaling (66.7%). All LET patients had pink-white background and linear vessels. Follicular plugs, peripheral pigmentation, and polymorphous vessels were lower in patients with mild CLASI activity than moderate activity (P = 0.036, 0.039, and 0.019, respectively). Fibrotic white dots, honeycomb pigment pattern, and blue-gray dots/globules were lower in those with mild CLASI damage scores than moderate damage (P = 0.010, 0.010, and 0.020, respectively). Peripheral pigmentation was more common in patients with lesion duration ≤12 months, while blue-gray dots/globules were more common with lesion durations >12 months. CONCLUSIONS Certain dermoscopic features may facilitate the differential diagnosis of DLE and LET.

Abstract
Cutaneous lupus erythematosus (CLE) is a group of diseases within the spectrum of lupus that primarily manifests with skin lesions. Discoid lupus erythematosus (DLE) is the most common subtype of CLE. Currently, there is no specific medication available for the treatment of CLE. Here, we reported the efficacy and safety of upadacitinib, a JAK1 selective inhibitor, in treating one DLE patient for 28 weeks. Upadacitinib 15mg QD alone improved DLE lesions significantly, while reduction of the drug to 15mg QOD led to a relapse of the skin lesions. Upadacitinib showed favorable safety in this DLE patient in the 28-week period, except for acne, which was controlled by topical application of benzoyl peroxide gel. In this case, we observed rapid and sustained improvement of DLE lesions using upadacitinib with favorable safety, which provided the opportunity to use upadacitinib as an alternative therapy for DLE.

Abstract
Cutaneous lupus erythematosus (CLE) is an autoimmune skin disease with various clinical forms, including the subtypes of discoid lupus erythematosus (DLE) and subacute cutaneous lupus erythematosus (SCLE). The altered function of the programmed cell death 1/programmed cell death ligand 1 (PD-1/PD-L1) axis in CLE pathogenesis has been suggested. Here, the soluble forms of PD-1 (sPD-1) and PD-L1 (sPD-L1) were explored in untreated DLE and SCLE. Levels of sPD-1 and sPD-L1 were determined by enzyme-linked immunosorbent assay in serums of 21 DLE, 18 SCLE, 13 systemic lupus erythematosus (SLE) patients and 20 healthy controls (HCs). Differences between patient groups and HCs, and the association between clinical activity of skin symptoms and sPD-1/sPD-L1 levels were analyzed with Mann-Whitney U-test and Spearmann's correlation. Regarding sPD-1 levels, no statistically significant differences were found between DLE and SCLE groups, nor compared to HCs. As for sPD-L1, a significantly lower level was found in the DLE group compared to the SCLE and HC groups (p = 0.027 and p = 0.009, respectively). In SLE, significantly higher sPD-1 was found compared to HCs (p = 0.002). No association between skin symptom activity and sPD-1/sPD-L1 levels was found in CLE. Alterations of the inhibitory effect of sPD-L1 on T-cell activity might elucidate the differences between DLE and SCLE.

Abstract
Discoid lupus erythematosus (DLE) is a chronic variant of cutaneous lupus erythematosus characterized by well-defined erythematous plaques with adherent scales and follicular plugging. The affected scalp shows erythema, edema, atrophy, alopecia, and telangiectasia. Trichoscopy of DLE shows branching capillaries, white patches, keratin plugs, reduced follicular ostia, and white dots and blue-gray dots arranged in speckles pattern. Prompt diagnosis and aggressive, early multimodal therapy helps in preventing disfiguring hair loss and psychosocial sequelae. Hereby, we present a case of reversal of hair loss in DLE with newer modalities of treatment such as injectable platelet-rich fibrin.

Abstract
Discoid lupus erythematosus (DLE) is a chronic autoimmune disease that primarily affects the skin, causing red, scaly patches that may be disfiguring and can cause permanent scarring. This study aimed to investigate the potential clinical and therapeutic applications of heme oxygenase-1 (HMOX1) in the context of DLE. Immunohistochemical staining and bioinformatics analysis were performed on skin biopsy samples from DLE patients to examine the levels of HMOX1 and to correlate with markers of inflammation. Our study revealed a negative correlation between HMOX1 levels and the inflammatory status of DLE lesions, as well as an inverse correlation between HMOX1 levels and the infiltration of M1 macrophages and activated mastocytes. These findings suggest that HMOX1 plays a crucial role in the regulation of inflammation in DLE and could be a potential therapeutic target and biomarker for DLE.

Abstract
BACKGROUND Cutaneous lupus erythematosus is an umbrella term for a group of autoimmune connective tissue disorders affecting the skin. Discoid lupus erythematosus (DLE) is the chronic condition and most common form of cutaneous lupus erythematosus. AIMS Current therapies of DLE are challenging and not completely satisfactory, highly expensive, off-label, or poorly available (like antimalarials due to COVID-19 outbreaks). Nicotinamide, also called niacinamide, is a water-soluble form of vitamin B3 (niacin). Its multiple effects let us think that nicotinamide could be a therapy for lupus-associated skin lesions. METHODS We performed a prospective randomized double-blind clinical trial on 60 subjects diagnosed with Discoid lupus erythematosus using topical Nicotinamide 2% and 4% preparations in form of cream and gel on skin and scalp lesions. Control group was included using only cream/gel base as placebo control. RESULTS Obtained data showed that topical Nicotinamide can be used for the treatment of DLE as adjuvant to other treatment regimens with good cosmetic results and minimal side effects. Topical 4% Nicotinamide is superior to 2% preparation in response but associated with a higher incidence of irritation. CONCLUSION Topical Nicotinamide can be used for the treatment of DLE as an adjuvant to other treatment regimens with good cosmetic results and minimal side effects. Further trials with long-term therapy, follow-up period, and bigger sample sizes are required.

Abstract
Discoid lupus erythematosus (DLE) is the most common type of cutaneous lupus and is clinically characterized by alopecia, depigmentation, and scars on sun-exposed skin. Squamous cell carcinoma is a potential long-term complication. The most important risk factor for squamous cell carcinoma development in people with dark skin is chronic scarring and inflammation, such as those seen in long-standing discoid plaques. African Americans who develop squamous cell carcinoma in the setting of chronic scarring and inflammation have a greater risk of metastasis and recurrence compared to sun-induced squamous cell carcinoma seen in whites. Despite this, the pathogenesis of squamous cell carcinoma development in chronic DLE is not fully understood. Herein, we describe a case of an African American patient who developed squamous cell carcinoma on a long-standing discoid plaque. Analysis of the lesion revealed a null type pattern of p53 protein expression and abundant CD123+ plasmacytoid dendritic cells, as potential drivers of oncogenesis and inflammation, respectively. Dermatologists should be aware of the increased risk of squamous cell carcinoma development within long-standing discoid plaques for a prompt early diagnosis and active long-term surveillance.

Abstract
Cutaneous lupus erythematosus (CLE) is divided into the following four clinical subtypes: acute CLE (ACLE), subacute (SCLE), chronic CLE (CCLE) and lupus erythematosus tumidus (LET). The aim of this study was to describe the dermoscopic patterns of CLE by clinical variant. A total of 54 Caucasian patients from Poland (ACLE = 10; SCLE = 11; CCLE = 26; LET = 7) were included. The predefined parameters for dermoscopic assessment in inflammatory dermatoses were analyzed separately by two dermatologists. Under dermoscopy, all the variants of CLE showed predominantly polymorphous vessels on a pink−red background within the lesional skin. Dotted vessels, in association with other vessel morphologies, were observed more frequently in SCLE than in the other subtypes of CLE, but the difference did not reach statistical significance (p = 0.07). The findings associated with hair follicles, including rosettes (p = 0.02), follicular plugs (p = 0.01), follicular red dots (p < 0.01), perifollicular white halos (p < 0.01) and dermoscopic features corresponding to scarring, including white (p = 0.01) and pink (p < 0.01) structureless areas, were significantly more common in CCLE than in other variants of CLE. A lack of scaling, pigmentation, erosions and crusting were observed in all the cases of LET. The role of dermoscopy as an auxiliary tool in the differential diagnosis of CLE needs further elucidation.

Abstract
OBJECTIVE Cutaneous lupus erythematosus (CLE) is a heterogenous skin disease. The two most common subtypes are discoid LE (DLE) characterized by scarring skin damage and acute CLE (ACLE) presenting with transiently reversible skin lesions. It remains unknown what causes the difference of skin lesions. Studies have shown the existence of tissue-specific 5-Hydroxymethylcytosine (5 hmC)-modified regions in human tissues, which may affect the tissue-related diseases. Here, we aim to assess the expression of 5 hmc in DLE and ACLE lesions and explore the relationship of 5 hmc with scarring damage in DLE. METHODS 84 CLE samples were included in the study. We evaluated the skin damage score and reviewed the histopathologic sections. Immunohistochemical staining was performed to detect the expression of 5 hmc in the appendage and periappendageal inflammatory cells. The 5 hmc expression in periappendageal lymphocytic cells was investigated by multi-spectrum immunohistochemistry staining. RESULTS Scarring/atrophy was the most significant damage in differentiating the DLE from ACLE. Perifollicular inflammatory infiltration was present in all patients with DLE scarring alopecia (DLESA). The 5 hmc expression in the appendage and periappendageal inflammatory cells was significantxly increased in DLESA than ACLE. Similar expression pattern was seen in the staining of IFN-alpha/beta Receptor (IFNAR). The expression of 5 hmc in the appendage was positively correlated with that in the periappendageal inflammatory cells. There was an increased 5 hmc expression in lymphocytes cluster around hair follicle consisting of CD4+ cells, CD8+ cells, and CD19+ cells in DLESA lesions. CONCLUSION These data demonstrate a close association of the expression pattern of 5 hmc with the histopathological characteristic distribution, and with the type I interferons (IFNs) signals in DLESA, supporting the importance of 5 hmc in the amplification of appendage damage and periappendageal inflammation, thereby offering a novel insight into the scarring damage of DLE and the heterogeneity of CLE skin lesions.

Abstract
Discoid lupus erythematosus (DLE) is the most common form of chronic cutaneous lupus erythematosus commonly seen in photoexposed regions. Eyelid involvement in DLE is relatively rare. We present three cases of DLE with eyelid involvement. It closely mimics many clinical conditions; hence, diagnosis is often late. When left untreated, it can lead to many complications. The aim of this case series is to emphasize that ophthalmologists and dermatologists are aware of the various presentations of DLE in eyelids to prevent any misdiagnosis.

Abstract
Description Alopecia of the scalp has various causes and presentations. However, linear alopecia is unusual and lupus erythematosus presenting as linear alopecia is exceedingly rare. To date, there have been 16 documented cases of linear alopecia diagnosed as chronic cutaneous lupus erythematosus occurring in a linear configuration following Blaschko's lines. We report 2 additional cases and review the clinical and histologic features along with treatment. This Blaschkoid linear variant of cutaneous lupus erythematosus has distinct clinical and histologic characteristics that set it apart from other causes of alopecia and from classic forms of cutaneous lupus. These distinct features include a linear configuration, a younger age of presentation, a disproportionate number of Asians affected, and a paucity of cases with systemic involvement. Histologically, the lesions are characterized by prominent mucin in the dermis and subcutaneous tissues. Blaschkoid linear lupus of the scalp is sufficiently distinctive to suggest the diagnosis on histology alone, in the appropriate clinical context. The most common and successful treatments included systemic and/or combination treatment with oral hydroxychloroquine, oral steroids, and/or intralesional steroids.

Abstract
BACKGROUND The coexistence of psoriasis and cutaneous lupus erythematosus (LE) is uncommon. Treatment for concomitant psoriasis and LE is challenging because some valid treatments for LE such as hydroxychloroquine and systemic corticosteroid are known to aggravate psoriasis. Th17 pathway is shared by these two disease entities. Thus, biologics targeting Th17 pathway, including ustekinumab and secukinumab, have been successfully used in the treatment of patients with concomitant psoriasis and LE. PURPOSE We report a patient with aggravation of discoid lupus erythematosus (DLE) after secukinumab treatment for psoriasis. RESEACH DESIGN Case report. STUDY SAMPLE One patient was included in this case report. DATA COLLECTION AND ANALYSIS Clinical and pathological pictures were presented after informed consent. RESULT Symptoms of psoriasis and psoriatic arthritis almost resolved after 150 mg secukinumab every four weeks for 2 years, but lesions of DLE enlarged and became generalized. CONCLUSION LE is a highly heterogeneous disease, and further studies are required to find the optimal treatment in patients suffering from both LE and psoriasis.

Abstract
Pediatric discoid lupus erythematosus (DLE) is a rare inflammatory skin disorder. This article aims to review all the available clinical and therapeutic data on reported cases of pediatric DLE. A systematic review of the literature was conducted using Pubmed and Embase with no limitation on publication date, sex, or nationality. Thirty-two articles were included with 201 cases, a mean age of 8.9 years (2 months-16 years) and an F:M ratio of 1.8. Lesions were located on the head and neck in 58.5% and were disseminated in 36.5% of the cases. Associated symptoms were pruritus (10.1%) and alopecia (8.7%). 12% progressed to systemic lupus erythematosus (SLE) and 14.5% had concurrent SLE. The only statistically significant predictor for progression to SLE was the onset of symptoms before or at the age of 10 years (p = 0.004). Treatments consisted mainly of sunscreens (26.3%), topical corticosteroids (24.3%), and oral antimalarials (25.3%). Retrospective nature of the included studies, small sample size, short duration of follow-up and limited data on the patients' demographics. Pediatric DLE affects mostly the head and neck, with a female predominance, a possible association with inflammatory and autoimmune diseases, and overall good treatment response and prognosis.

Abstract
Introduction Lupus erythematosus (LE) is an autoimmune disease with a strong influence of genetic and environmental factors. C-C motif chemokine receptor 5 (CCR5) gene expression may affect the development and intensity of LE. Aim To evaluate the possible association between the 32bp deletion in rs333 locus located within the CCR5 gene and the development of LE or the occurrence of various clinical symptoms in the course of the disease. Material and methods One hundred and twenty patients with LE (77 with systemic lupus erythematosus (SLE) and 43 with discoid lupus erythematosus (DLE)) and 100 healthy controls from the Polish population were genotyped for deletion in rs333. Results 32 bp deletion in the rs333 was significantly more frequent among healthy individuals than DLE patients. Moreover, heterozygotes and homozygotes with deletion in rs333 were significantly more frequent within the control group than the group of patients with discoid lupus erythematosus. In contrast, any statistically significant differences in allele or genotype frequencies between healthy persons and SLE patients were observed. Furthermore, nucleotide sequence variability of rs333 was not associated with certain clinical symptoms of LE patients. Conclusions Deletion in the rs333 might be a protective factor for DLE, but not SLE in the Polish population. Nevertheless further studies performed on larger populations are needed to confirm these observations.

Abstract
BACKGROUND Tissue resident memory T cells (TRMs) persist long-term in peripheral tissues without recirculation, triggering an immediate protective inflammatory state upon the re-recognition of the antigen. Despite evidence incriminating the dysregulation of TRMs in autoimmune diseases, few studies have examined their expression in cutaneous lupus erythematosus (CLE). OBJECTIVES We aimed to examine whether there are differences among TRM populations in CLE depending on different clinical conditions, such as the CLE subtype or association with systemic lupus erythematosus, and to determine the effect of type I interferon (IFN) on the development of TRMs in CLE. METHODS CLE disease activity was evaluated using the Cutaneous Lupus Erythematosus Disease Area and Severity Index. The expression of the TRM markers CD69 and CD103 in CLE lesions was evaluated by immunofluorescence. Flow cytometry was performed on peripheral blood mononuclear cells after IFNα treatment. RESULTS The number of TRMs expressing either CD69 or CD103 was significantly higher in CLE lesions than in control skin; however, it was not significantly different between discoid lupus erythematosus and subacute CLE, or dependent on the presence of concomitant systemic lupus. Lesional severity was not correlated with an increase in TRMs in CLE. IFNα treatment induced a conspicuous increase in CD69 expression in skin-homing T cells, more profoundly in CD4+ T cells than in CD8+ T cells. CONCLUSIONS Skin TRMs, either CD69 or CD103-positive cells, showed increased levels in the lesional skin of CLE, and IFNα increased the expression of CD69 in T cells.

Abstract
ABSTRACT Discoid lupus erythematosus (DLE) is the most common skin manifestation of lupus; however, the molecular mechanisms underlying DLE remain unknown. Therefore, we aimed to identify key differentially expressed genes (DEGs) in discoid lupus skin and investigate their potential pathways.To identify candidate genes involved in the occurrence and development of the disease, we downloaded the microarray datasets GSE52471 and GSE72535 from the Gene Expression Database (GEO). DEGs between discoid lupus skin and normal controls were selected using the GEO2R tool and Venn diagram software (http://bioinformatics.psb.ugent.be/webtools/Venn/). The Database for Annotation, Visualization, and Integrated Discovery (DAVID), Enrichr, and Cytoscape ClueGo were used to analyze the Kyoto Encyclopedia of Gene and Genome pathways and gene ontology. Protein-protein interactions (PPIs) of these DEGs were further assessed using the Search Tool for the Retrieval Interacting Genes version 10.0.Seventy three DEGs were co-expressed in both datasets. DEGs were predominantly upregulated in receptor signaling pathways of the immune response. In the PPI network, 69 upregulated genes were selected. Furthermore, 4 genes (CXCL10, ISG15, IFIH1, and IRF7) were found to be significantly upregulated in the RIG-I-like receptor signaling pathway, from analysis of Enrichr and Cytoscape ClueGo.The results of this study may provide new insights into the potential molecular mechanisms of DLE. However, further experimentation is required to confirm these findings.

Abstract
Background Linear cutaneous lupus erythematosus is a rare subtype of lupus erythematosus (LE) that develops linear lesions following the lines of Blaschko. Linear cutaneous lupus erythematosus may present as various subtypes of LE, including linear discoid lupus erythematosus. There are few reports about pigmentedlinear discoid lupus erythematosus in the literature. Aims We aimed to summarize the clinical and pathological features of patients with pigmented linear discoid lupus erythematosus following the lines of Blaschko. Methods Eighteen patients with pigmented linear discoid lupus erythematosus attending the outpatient department of the Dermatology, Peking Union Medical College Hospital, China, were enrolled in the study. We recorded clinical data including sex, age at onset, disease duration, location and distribution of the lesions, symptoms, trigger factors, antinuclear antibody (ANA) testing, therapy, and therapeutic responses. Histopathological features were also summarized. Results All 18 patients presented with well-defined brownish pigmented linear or segmental macules or plaques, following the lines of Blaschko. All the lesions were located on the head or neck. Unilaterally distributed lesions were found in 94.4% of patients. Two patients showed low titers of ANA in a speckled pattern. No systemic involvement or progression to systemic LE was noted. The patients were clinically diagnosed as pigmented lichen planus (55.6%), pigmented linear discoid lupus erythematosus (33.3%), and linear morphea (11.1%) before histopathological examination. Limitations The study was retrospective and direct immunofluorescence was not performed. Not all patients' information was available and 4 patients were lost to follow-up because their contact information was changed. Conclusion Pigmented linear discoid lupus erythematosus mostly occurs on the head and neck. It manifests as brownish macules along the lines of Blaschko. Differentiation between pigmented linear discoid lupus erythematosus and other dermatoses that have a linear distribution can be difficult both clinically and pathologically, but histological details can help distinguish them.

Abstract
Alopecia for patients with discoid lupus erythematosus can sometimes be a refractory condition, where mixed infiltrates of T lymphocytes and histiocytes leads to destruction of hair follicles, which might cause permanent scarring. Early diagnosis and timely treatment can achieve hair regeneration and prevent further disease progression. Concentrated growth factor, a novel autologous plasma extract, contains various growth factors that could promote tissue regeneration. In this article, we report a case of cell growth factor combined with corticosteroids for the treatment of discoid lupus erythematosus alopecia. This case study concludes with satisfactory clinical effect.

Macrophage Migration Inhibitory Factor (MIF) and Its Homologue d-Dopachrome Tautomerase (DDT) Inversely Correlate with Inflammation in Discoid Lupus Erythematosus. Molecules 2021; 26:molecules26010184.

Abstract
Discoid Lupus Erythematosus (DLE) is a chronic cutaneous disease of unknown etiology and of immunoinflammatory origin that is characterized by inflammatory plaques and may lead to disfiguring scarring and skin atrophy. Current treatments are limited, with a large proportion of patients either poorly or not responsive, which makes DLE an unmet medical need. Macrophage migration inhibitory factor (MIF) is the prototype of a pleiotropic family of cytokine that also includes the recently discovered homologue D-dopachrome tautomerase (DDT) or MIF2. MIF and DDT/MIF-2 exert several biological properties, primarily, but not exclusively of a proinflammatory nature. MIF and DDT have been suggested to play a key role in the pathogenesis of several autoimmune diseases, such as multiple sclerosis and type 1 diabetes, as well as in the development and progression of certain forms of cancers. In the present study, we have performed an immunohistochemistry analysis for the evaluation of MIF in DLE lesions and normal skin. We found high levels of MIF in the basal layer of the epidermis as well as in the cutaneous appendage (eccrine glands and sebocytes) of normal skin. In DLE lesions, we observed a significant negative correlation between the expression of MIF and the severity of inflammation. In addition, we performed an analysis of MIF and DDT expression levels in the skin of DLE patients in a publicly available microarray dataset. Interestingly, while these in silico data only evidenced a trend toward reduced levels of MIF, they demonstrated a significant pattern of expression and correlation of DDT with inflammatory infiltrates in DLE skins. Overall, our data support a protective role for endogenous MIF and possibly DDT in the regulation of homeostasis and inflammation in the skin and open up novel avenues for the treatment of DLE.

Abstract
In recent years, calcineurin inhibitors have been used as the first line alternative to topical corticosteroids in the treatment of discoid lupus erythematosus (DLE). We aim to evaluate the efficacy and safety of topical tacrolimus 0.1% vs topical halobetasol propionate 0.05% in patients with DLE. This comparative study was carried out in the Department of Dermatology and Venereology, Chittagong Medical College Hospital (CMCH), Bangladesh between the period of July 2018 and June 2019. The change of DLE activity assessed with the cutaneous lupus erythematosus disease area and severity index was used as a primary outcome measure. The effective sample was 40 patients in each group. Both groups were similar in terms of baseline demographic and clinical characteristics. After 8 weeks of treatment, the mean total erythema score decreased significantly in both groups (in tacrolimus treated group [TTG] from 12.53 ± 8.05 to 8.03 ± 5.69, [P < .001] and in halobetasol propionate treated group [HTG] from 11.83 ± 7.17 to 7.30 ± 4.56 [P < .001]), as well as the mean total scale/hypertrophy score (in TTG from 8.08 ± 5.30 to 4.33 ± 3.21; [P < .001] and in HTG from 7.40 ± 4.73 to 3.68 ± 2.01, [P < .001]. The magnitude of reduction was significantly better in HTG [P = .032]). The mean total activity score decreased significantly in both groups (in TTG from 22.95 ± 13.40 to 14.33 ± 8.89, [P < .001] and in HTG from 22.15 ± 11.95 to 13.7 ± 7.22, [P < .001]). The present study demonstrated that tacrolimus 0.1% ointment and halobetasol propionate 0.05% ointment had a comparable efficacy in DLE patients; however, halobetasol showed significantly better improvement regarding scaly, hypertrophic lesions.

Abstract
BACKGROUND Discoid lupus erythematosus (DLE) may lead to disfiguring scarring and permanent hair loss. Dermoscopy may serve as a noninvasive tool useful in the preliminary diagnosis of hair loss and inflammatory skin diseases. The aim of the paper was to summarize and analyze the dermoscopic features of DLE lesions in various anatomical locations. METHODS A systematic review of PubMed, Scopus and Web of Science was performed using the search terms: 'lupus' OR 'discoid lupus' OR 'cutaneous lupus' combined with 'dermoscopy' OR 'dermatoscopy' OR 'videodermoscopy' OR 'videodermatoscopy' OR 'trichoscopy' OR 'mucoscopy' OR 'onychoscopy'. RESULTS About 29 out of 318 initially identified papers were included in the analysis. In scalp DLE (n = 166), the most common findings were: white structureless areas (62%), arborizing vessels (57.8%), white scales (54.2%), follicular keratotic plugs (47%), absent follicular openings (45.8%), perifollicular scaling (43.9%), pink-white background (40.4%), speckled brown pigmentation (38%), and fibrotic white dots (33.7%). In non-scalp DLE (n = 129), the most frequent features were: follicular keratotic plugs (66.7%), white perifollicular halo (65.9%), white scale (39.5%), speckled brown pigmentation (38.8%), white structureless areas (37.2%), and arborizing vessels (34.9%). There are scarce data in the literature on dermoscopic findings in labial (n = 8), mucosal (n = 3) and ungual DLE (n = 1). CONCLUSIONS DLE is characterized by a wide variety of dermoscopic findings with variable frequencies depending on the location of the lesions. Nevertheless, further studies are needed in order to reliably assess frequencies, correlation with disease stage and significance of individual dermoscopic features.

Abstract
A 43-year-old male presented with shortness of breath and palpitations. Physical examination was significant for skin lichenification, an erythematous maculopapular rash with annular plaques, a fissured tongue, and digital clubbing. Electrocardiogram captured a supraventricular tachycardia and right bundle branch block. Left heart catheterization found several proximal left coronary artery branch aneurysms, a right coronary-pulmonary artery fistula, venous-luminal vessels between the right heart chambers and cardiac veins, and thebesian venous lakes. Functional cardiac capacity was reduced, with left ventricular ejection fraction of 35 to 40%, on ventriculogram. A diagnosis of discoid lupus erythematosus was established after skin biopsies revealed systemic lupus erythematosus-like features but negative anti-nuclear, anti-Smith, anti-ds-deoxyribonucleic acid, anti-Ro, and anti-La antibodies. The case reported is unique, in that while our patient had pathologic electrophysiologic changes typically seen with autoimmune disease, the patient had many anatomical cardiac anomalies without atherosclerotic coronary disease. It is uncertain whether these findings are purely incidental or are related to an underlying genetic disorder.

Gene Co-expression Networks Identifies Common Hub Genes Between Cutaneous Sarcoidosis and Discoid Lupus Erythematosus. Front Med (Lausanne) 2020; 7:606461.

Abstract
In this study we analyzed gene co-expression networks of three immune-related skin diseases: cutaneous sarcoidosis (CS), discoid lupus erythematosus (DLE), and psoriasis. We propose that investigation of gene co-expression networks may provide insights into underlying disease mechanisms. Microarray expression data from two cohorts of patients with CS, DLE, or psoriasis skin lesions were analyzed. We applied weighted gene correlation network analysis (WGCNA) to construct gene-gene similarity networks and cluster genes into modules based on similar expression profiles. A module of interest that was preserved between datasets and corresponded with case/control status was identified. This module was related to immune activation, specifically leukocyte activation, and was significantly increased in both CS lesions and DLE lesions compared to their respective controls. Protein-protein interaction (PPI) networks constructed for this module revealed seven common hub genes between CS lesions and DLE lesions: TLR1, ITGAL, TNFRSF1B, CD86, SPI1, BTK, and IL10RA. Common hub genes were highly upregulated in CS lesions and DLE lesions compared to their respective controls in a differential expression analysis. Our results indicate common gene expression patterns in the immune processes of CS and DLE, which may have indications for future therapeutic targets and serve as Th1-mediated disease biomarkers. Additionally, we identified hub genes unique to CS and DLE, which can help differentiate these diseases from one another and may serve as unique therapeutic targets and biomarkers. Notably, we find common gene expression patterns in the immune processes of CS and DLE through utilization of WGCNA.

Discoid lupus erythematosus (DLE) is the most common variant of chronic cutaneous lupus erythematosus. Several cases of Blaschko-linear lupus erythematosus, which is regarded as a distinct subtype of lupus erythematosus, have been reported across the globe. Dermatomal involvement in DLE is rare and that too has been reported in patients of systemic lupus erythematosus at site of healed herpes zoster either as an isomorphic or isotopic phenomenon. Here, we report a case of DLE on account of its unusual morphology, de novo multidermatomal configuration, without previous episode of herpes zoster or trauma.

Abstract
INTRODUCTION Between 5 and 25% of patients with cutaneous lupus erythematosus (CLE) can progress to systemic lupus erythematosus (SLE) during the course of the disease. There is no clear predictive guideline for the progression of CLE to SLE. AREAS COVERED Lupus erythematosus (LE), a chronic autoimmune disease, has a wide spectrum of manifestations. On one side of the spectrum is CLE, in which patients only display skin lesions. On the other side of the spectrum is SLE, which develops severe systemic involvement. CLE has even been considered as a separate entity from LE, while CLE is also proposed to be associated with SLE. In this review, the authors will describe the relationship between CLE and SLE; summarize the incidence, risk factors, systemic involvement, and management of patients who transition to SLE. The literature search was conducted mainly through PubMed from March to July 2020. EXPERT OPINION The identification of clinical characteristics and biomarkers in patients facing risk of developing SLE and monitoring the disease on a regular basis are essential to promptly manage and hopefully prevent transition to the systemic form.

Successful treatment of facial localized discoid lupus erythematosus with intralesional betamethasone: A report of three cases. Dermatol Ther 2020; 33:e13389.

Abstract
Discoid lupus erythematosus (DLE) is a chronic autoimmune skin disease that usually causes disfiguring scarring, dyspigmentation, and atrophy. Despite a range of available topical and systemic therapies, the treatment of DLE remains a therapeutic challenge, especially in some refractory cases. Here, we reported three male patients with long-term chronic lesions of unilateral facial localized DLE, who failed to have their disease controlled with many previous topical/systemic treatments, showed rapid and well response to intralesional injections of betamethasone (2 mg/mL, 0.2 mL/site) monotherapy once every 2 weeks for two, two, and four times of treatment, respectively. Intralesional betamethasone may provide a safe and effective alternative in the management of refractory localized DLE skin lesions.

Value of CD123 Immunohistochemistry and Elastic Staining in Differentiating Discoid Lupus Erythematosus from Lichen Planopilaris. Int J Trichology 2020; 12:62-67. [PMID: 32684677 PMCID: PMC7362963 DOI: 10.4103/ijt.ijt_32_20] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 03/17/2020] [Accepted: 04/08/2020] [Indexed: 12/03/2022] Open
Abstract
Background: Differentiating scarring alopecia secondary to lichen planopilaris (LPP) and discoid lupus erythematosus (DLE) has always been a challenge clinically and pathologically. Plasmacytoid dendritic cells (PDCs) have been reported in the cutaneous lupus erythematosus by CD123 immunostaining. This study assesses CD123 marker positivity and patterns of elastic fiber loss in scalp biopsy to differentiate DLE from LLP. Patients and Methods: Forty-three cases with clinical and pathological diagnosis of LPP and DLE were selected, and CD123 immunohistochemistry staining and elastic staining were performed on them. The presence of CD123-positive cells, clustering and distribution of cells, and patterns of elastic fibers loss in the dermis were evaluated. To analyze the data, the Chi-square test was used; moreover, the sensitivity and specificity of CD123 were calculated based on a diagnostic test for 2-by-2 tables. Results: Infiltration of PDC was seen in 90% of DLE cases. The presence of more than 10% and 20% PDC cells in inflammatory cells had 90% and 85% sensitivity and 34.7% and 91.3% specificity, respectively. PDC clusters more than 20 cells had 100% specificity for DLE. Location and patterns of PDC infiltration were not statistically significant (P = 0.378). The wedge-shaped loss of elastic fibers and the diffuse loss were the dominant patterns in LPP and DLE, respectively (P = 0.006). Conclusion: Our results suggested that CD123 along with elastic staining and histological features might be useful to diagnose challenging cases of lymphocytic scarring alopecia with clinical differential diagnosis of LPP and DLE.

Abstract
Hypertrophic lupus erythematosus is a variant of discoid lupus erythematosus, which manifests as verrucous plaques and/or keratoacanthoma-like nodules on the face and arms. Diagnosis and treatment of hypertrophic lupus erythematosus can be challenging as it can resemble cutaneous squamous cell carcinoma clinically and histopathologically. Furthermore, cutaneous squamous cell carcinoma is a known complication of discoid lupus erythematosus. We present a diagnostically challenging case of a patient with a rapidly enlarging rhinophymatous mass and multiple keratoacanthoma-like lesions of the bilateral upper extremities whose work-up was initially equivocal. CD123 staining helped to elucidate a final diagnosis of cutaneous squamous cell carcinoma arising in a background of occult hypertrophic lupus erythematosus.

Melanocytic and pseudomelanocytic nests coexist in interface dermatitis from head-neck sun-exposed skin: A report of three cases. J Cutan Pathol 2020; 47:649-653.

Abstract
Discrete junctional cellular aggregates ("nests"), partially staining with melanocytic markers, are described in lichenoid tissue reaction, mainly from chronically sun-exposed skin. The concomitant epidermal flattening and papillary dermal fibrosis with melanophages, may raise the differential diagnosis to that of a regressing melanoma. We describe three cases of interface dermatitis of the head/neck area with clinicopathological features of melanotic discoid lupus erythematosus. These cases showed junctional aggregates, a few composed of inflammatory cells and colloid bodies ("pseudomelanocytic nests"), while others composed of S100- but MART-1+, MITF+, and SOX-10+ cells ("true melanocytic nests"); negativity of the melanocytic component for PRAME was a clue to benignity. True junctional melanocytic nesting may be induced by lichenoid dermatoses on chronically sun-damaged skin. The presence of colloid bodies and of the double negativity for S100 (within nests) and PRAME (both within nests and single melanocytes), together with clinicopathological correlation, avoids misdiagnosis.

Abstract
The occurrence of Tolosa-Hunt syndrome (THS) in the setting of discoid lupus erythematosus (DLE) has not been previously reported. We report a case of a 55-year-old Chinese man with established cutaneous lupus who presented with 1 week of worsening blurry vision and ptosis of the left eye with severe headache 2 weeks prior to presentation. His cranial nerve examination was significant for left afferent pupillary defect, red desaturation, ptosis, and oculomotor nerve palsy. He also presented with active DLE lesions. Magnetic resonance imaging brain demonstrated asymmetric thickening and enhancement of the left cavernous sinus consistent with THS. After a 4-week gradual steroid taper his ophthalmoplegia resolved. The unusual occurrence of THS and DLE prompts consideration of nonsystemic autoimmune disorders in diagnosis of THS.
