Scabies Norvegica in infant

Introduction: Crusted scabies are a rare manifestation of scabies characterized by uncontrolled proliferation of mites in the skin. Crusted scabies are a severe variant of highly contagious scabies. Various cutaneous, neurologic and immunologic diseases have been described to predispose to crusted scabies. Case presentation: The presented case is a 7-month-old male. He was hospitalized at the Clinic of Dermatovenerology, due to hyperkeratotic changes in the palms and food, papules throughout the body, and nail changes all of these accompanied by scratching. Initially, it was diagnosed as atopic dermatitis, hyperkeratosis palmoplantaris, and onychomycosis mani. The changes had started to appear five months ago. Also, the mother of the child presents the papules throughout the body, also associated with itching as classical scabies. Conclusion: Crusted scabies are a severe variant of highly contagious scabies. Is known the failure of the immune system to suppress the proliferation of the mite is an important cause of crusted scabies development. Crusted scabies usually do not present as an acute eruption as in classical scabies. The eruption is slow in onset and insidious in progression. In the present case, we learned that in the stimulation of the condition, there was a major role in the application of topically fluoride steroids.

Proliferative papulo‐nodular glossitis due to Leishmania infantum in a dog

AbstractCanine leishmaniosis, caused by the protozoan Leishmania infantum, is an endemic vector‐borne disease in Europe. From a diagnostic point of view, the disease can sometimes be a real challenge for the clinician, due to the variability of clinical presentations in a sick dog. These clinical signs can be classified, based on the frequency of presentation, in typical and atypical signs. In dogs is common to find different clinical presentations of cutaneous disease and systemic involvement, while clinical presentations in mucosa are not so common. A 6‐year‐old, entire, male German shepherd crossbred dog was examined for evident nodular lesions on the tongue. The most important laboratory alteration detected was hyperglobulinemia with an increase in the gamma fraction classified as polyclonal gammopathy. High anti‐Leishmania antibodies were detected by ELISA. Tongue biopsy samples were obtained from the lesions with the presence of a diffuse inflammatory infiltrate characterised by macrophages and neutrophils with no compatible forms of Leishmania parasites. However, the presence of Leishmania amastigotes was confirmed by specific immunohistochemistry. A good clinical response to the anti‐Leishmania based on meglumine antimoniate and allopurinol was observed after meglumine antimoniate administration. This clinical case describes the presentation of proliferative papulo‐nodular glossitis in an L. infantum‐positive dog as the most evident clinical finding reported.

Cutaneous Toll-like Receptor 9 Pre-Defines Hydroxychloroquine Dosage in Patients with Both Discoid and Subacute Lupus Erythematosus.

Background and Objectives: Cutaneous lupus erythematosus (CLE) presents clinically heterogeneous manifestations, partially explained by the different expression of Toll-like receptors (TLRs) type 8 and 9, located to endosomal compartments where they are poised to recognize microbial nucleic acids. This disease is empirically treated with hydroxychloroquine (HCQ), which is hallmarked with a safe and effective profile, but induces a slow and sometimes clinically insufficient therapeutic response. Currently, no biomarkers predictive of response are validated or even proposed in the scientific literature. We aimed to evaluate endosomal TLR type 7, 8 and 9 as predictive biomarkers of HCQ efficacy. Materials and Methods: We conducted a case-control study comparing CLE patients retrospectively assigned to three subgroups based on 3-6-month Cutaneous LE Disease Area and Severity Index (CLASI) reduction upon treatment with HCQ (I = <40% vs. II = 40-80% vs. III = >80%). Before HCQ, lesional skin specimens were collected in untreated CLE and through immunohistochemistry; TLR-7, -8 and -9 expression was evaluated in the epidermis and the lymphocytic infiltrate was evaluated in the dermis. Results: Sixty-six lesional skin biopsies were compared with healthy controls. CLE patients displayed lower epidermal expression of total TLR 8 and 9 as well as infiltrating TLR-8, TLR9 + lymphocytes compared to controls. High HCQ responders differed from low responders for TLR-9 positivity (high vs. low) and for the lymphocytic dermal infiltrate (high vs. low). Conclusions: TLR9 could be envisaged as a possible biomarker to predict HCQ response level and dosage in CLE patients.

Treatment of Patient with Cutaneous Lupus Erythematosus with Roflumilast Cream 0.3%

Introduction: Cutaneous lupus erythematosus (CLE) is the cutaneous form of a common autoimmune disease, lupus erythematosus, driven by a dysfunction within the adaptive and innate immune system. CLE is subcategorized further into acute, subacute and chronic disease. Here we report a case of a patient with systemic and refractory cutaneous disease with improvement in manifestations demonstrating efficacy following treatment with roflumilast cream 0.3% in a complex chronic CLE patient with uncontrolled disease, intense pruritus and scarring. Case Report: A 48-year-old Asian female with history of smoking, chronic refractory SLE since 2008 with a new onset of pruritic rash. Previous therapies including thalidomide, hydroxychloroquine, methotrexate, mycophenolate mofetil, numerous research trials, oral and intramuscular steroids that failed to control her systemic LE. A Rheumatology colleague referred the patient for new onset cutaneous manifestations. Initial presentation revealed lesions involving 2% of the occipital scalp. Pathology confirmed the diagnosis of discoid lupus. Intralesional triamcinolone , plus topical betamethasone dipropionate 0.05% twice daily (BID) and timolol 0.5% OP solution for wound healing were initiated. Fifteen months later the patient had disease progression of her CLE on to her scalp, face, legs and arms, with the chief complaint of persistent pruritus despite oral prednisone, hydroxychloroquine and thalidomide. The patient’s rheumatologist requested alternative treatment for cutaneous disease without use of long term topical high potency steroids. A second series of intralesional triamcinolone injections plus betamethasone dipropionate 0.05% BID for 3-4 weeks and titrate down to 2-3 applications per week, and addition of roflumilast cream 0.3% was initiated once daily to her face, scalp, and lower legs. On the third office visit, four weeks later, the patient reported pruritus and cutaneous manifestations in lower legs controlled and scalp and face have marked improvement. After 8 weeks on this regimen, the patient return reported that scalp and face continued to improve and disease on the legs continue to be controlled despite not using topical treatment for four weeks. Roflumilast cream 0.3% once daily was continued as monotherapy. Two months later, the patient reported that her skin was fully controlled was starting to repigment with monotherapy. Conclusions: This case report of a 48-year-old female with refractory treatment resistant chronic SLE and CLE treated with roflumilast cream 0.3%, a phosphodiesterase-4 (PDE-4) inhibitor, resulted in disease control, the symptom improvement of improved pruritus as well as repigmentation of the skin. The results observed in this patient suggest this topical intervention, if implemented at the beginning of treatment for cutaneous onset of disease, may have the potential to halt the progression of cutaneous involvement. This case report serves to highlight a promising intervention that may lead to better cutaneous control without long term side effects of topical steroid use.

Cutaneous vasculitis in autoinflammatory diseases.

Autoinflammatory diseases (AIDs) characterized by recurrent episodes of localized or systemic inflammation are disorders of the innate immune system. Skin lesions are commonly found in AIDs and cutaneous vasculitis can coexist with AIDs and even present as the most striking feature. This review aims to focus on the frequent cutaneous vasculitis association in three monogenic AIDs including familial Mediterranean fever (FMF), deficiency of adenosine deaminase type 2 (DADA2), and the recently identified adult-onset VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome. Cutaneous vasculitis in FMF is characterized by: (1) small-vessel vasculitis similar to IgA vasculitis with palpable purpura but increased intussusception complication and less vascular IgA deposit, and (2) cutaneous arteritis-like vasculitis presenting as subcutaneous nodules most often with higher glomerular involvement. DADA2 has a wide spectrum of clinical presentations ranging from fatal systemic vasculitis with multiple strokes, especially in pediatric patients, to limited cutaneous disease in middle-aged patients. DADA2 shares similar clinical and histopathological features with polyarteritis nodosa (PAN). As a result, DADA2 is commonly initially misdiagnosed as childhood PAN. Livedo racemosa reveals the most common cutaneous manifestation of cutaneous vasculitis in patients with DADA2. VEXAS syndrome is a life-threatening disease. A diagnosis of VEXAS syndrome should be strongly considered or could be made in patients with skin lesions characterized by Sweet syndrome-like eruption, livedo racemosa, concomitant relapsing polychondritis, deep venous thrombosis, pulmonary involvement, and progressive hematologic abnormalities such as myelodysplastic syndrome with a unique finding of cytoplasmic vacuoles in myeloid and erythroid precursor cells from bone marrow aspirate smear. As skin involvement is common in AIDs and may present as the most frequent manifestation, especially in DADA2 (70% to 90%) and VEXAS syndrome (83% to 91%), dermatologists play a crucial role in contributing to the early diagnosis of these AIDs with early initiation of the appropriate therapy to avoid progressing fatal outcomes.

Disease progression and changes in KL-6 in patients with limited cutaneous systemic sclerosis-associated interstitial lung disease

BackgroundLittle is known about the annual change in Krebs von Lungen-6 (KL-6) and its correlation with forced vital capacity (FVC) in limited cutaneous systemic sclerosis-associated interstitial lung disease (lcSSc-ILD). We aimed to clarify the correlation during the clinical course. MethodsWe retrospectively reviewed data from consecutive patients with lcSSc-ILD. We measured FVC and KL-6 annually and calculated their annual changes using the difference in absolute values. Decline in FVC was defined as annual decline in FVC ≥5 %. ResultsThirty-eight patients with SSc-ILD were included. The median age was 62 years and 58 % were female. The median FVC was 87.3 % and the median KL-6 was 1629 U/ml. The median observation period was 55.2 months and the annual changes in FVC and KL-6 were evaluated 151 times simultaneously. The annual change in KL-6 had a significant negative correlation with that in FVC in the first year from the initial evaluation (from the baseline to one-year follow-up) (r = −0.819, p < 0.01), but not after the first year. In the multivariable analysis adjusted by age, sex, and FVC at each year, the annual change of KL-6 (per 100 U/ml) was significantly associated with decline in FVC in the first year (odds ratio: 3.03, 95 % confidence interval: 1.21–7.59, p = 0.02), but not after the first year. ConclusionsOnly in the first year from the initial evaluation, there was negative correlation between the annual change in FVC and that in KL-6 and the annual elevation in KL-6 was associated with decline in FVC in patients with lcSSc-ILD.

Iranian psoriasis registry: Research protocol and preliminary results of a pilot study.

Psoriasis as a common cutaneous inflammatory disease affect many aspects of patients' life. Disease registries render it possible to collect valuable data regarding a disease prevalence and burden as well as long-term observations concerning possible therapeutic regimens. This registry was designed for the ongoing systematic data collection on patients with psoriasis at two referral dermatology centers in Iran. The pilot phase of the registry was used to identify possible obstacles in the application and execution of systematic registration. A total of 281 patients were registered with the mean age of 42.02 years. The disease duration was 12.06 ± 10.90 years with the variety of clinical presentations. There was no significant difference between males and females in the age of disease onset (p = 0.53). Notably, 167 patients had children. Among them, 13 had children with psoriasis. The gender of the affected parent did not affect the possibility of psoriasis transmission to the child, and no significant difference was seen between the two sexes (P = 0.569). Regarding treatment, 99.4% of patients (n = 280) had used topical agents, 52.3% (n = 147) biologics, and 60.9% (n = 171) nonbiologic medications. Clinical trials report the efficacy and safety data regarding limited study populations in a restricted time window, and the results may differ from the general population. This highlights the importance of registry-based studies for collecting and analyzing longitudinal information. In terms of long-term disease complications such as malignancies, cardiovascular events, and serious adverse events, registry-based studies will help clinicians better recognize and manage each disease.

Efficacy and safety of repository corticotropin injection for refractory cutaneous dermatomyositis: a prospective, open-label study.

Cutaneous dermatomyositis (DM) is often refractory to multiple medications. Repository corticotropin injection (RCI) is FDA-approved for DM, but little is known about its efficacy and safety for treating cutaneous DM. We conducted a prospective, open-label trial assessing efficacy and safety of RCI for treating refractory cutaneous DM. DM patients with moderate-to-severe cutaneous activity [Cutaneous Dermatomyositis Disease Area and Severity Index activity (CDASI-A)] >14 despite prior treatment with ≥2 systemic agents were enrolled. Patients were initiated on 80 u RCI twice weekly for 6 months. Primary outcomes included significant decreases in CDASI-A and Physician's Global Assessment (PGA) scores at 6 months. Of nineteen patients enrolled, fifteen patients (11 females, 4 males) with DM (7 classic, 8 amyopathic) completed 6 months of RCI treatment. Patients were treated with a median 3.0 systemic medications prior to enrolment and were taking a median of 2.0 systemic medications at enrolment. Median baseline CDASI-A score was 19.0 and median PGA activity score was 2.5/10. For patient-reported outcomes, baseline median patient global skin score (PtGSS) was 3.0/10 and median dermatology life quality index (DLQI) score was 7.0/10. At 6 months, there were statistically significant improvements in CDASI-A scores (median= 10.0), PGA scores (median= 0.8/10), PtGSS scores (median= 7.0) and DLQI scores (median= 2.0), among others. Adverse effects were mild. RCI treatment resulted in statistically significant and clinically meaningful improvement in cutaneous DM activity and quality of life. Our results suggest RCI is an effective, safe, and well-tolerated treatment for patients with refractory cutaneous dermatomyositis. This clinical trial was registered with ClinicalTrials.gov (ClinicalTrials.gov Identifier: NCT01906372).

Anifrolumab for systemic lupus erythematosus: A clinical study of Japanese patients in Kanazawa University Hospital.

We investigated the effectiveness of anifrolumab in treating systemic lupus erythematosus (SLE). We treated seven patients with SLE (age range, 31-68 years; median age, 48 years); one male and six females) with anifrolumab between January 2022 and February 2023 at Kanazawa University Hospital. The period between the onset and initiation of anifrolumab treatment was 60-276 months (median, 234 months), and the SLE disease activity index-2000 (SLEDAI-2 K) before treatment was 2-6 months (median, 3 months). Five patients experienced skin rashes or alopecia, and their cutaneous lupus erythematosus disease area and severity index (CLASI) activity scores were 2-9 (median, 4). Six patients continued treatment with anifrolumab, but one did not because of uncontrolled pleurisy and pericarditis. Our results demonstrated that anifrolumab was effective in treating SLE and reducing both SLEDAI-2 K and CLASI activity scores (median decrease, 100%). Furthermore, the oral corticosteroid dosage could be reduced in all patients who were able to continue treatment. Our findings indicate that anifrolumab is effective not only for reducing disease and eruption activities, but also facilitates tapering of corticosteroid dosage.

A case series of hydroxychloroquine exacerbating the dermatomyositis rash.

Hydroxychloroquine (HCQ) is an antimalarial agent that is commonly used in the management of rheumatic skin disease. Few reports exist documenting exacerbation of dermatomyositis (DM) related to HCQ. Herein, we describe three adult patients with worsening DM cutaneous disease after starting HCQ and resolution or improvement with cessation. The time to exacerbation ranged from two weeks to nine months after the initiation of HCQ 400mg/day. Two of the three patients had antibodies to transcription intermediary factor 1γ (TIF1γ) and the other had antibodies to anti-nuclear matrix protein 2 (NXP2). After discontinuation of HCQ, the time to improvement or resolution of cutaneous symptoms ranged from six weeks to six months. Hydroxychloroquine may be associated with worsening cutaneous features in DM. In patients who are not improving despite escalation of immunosuppressive medications, or are worsening, we recommend a trial of discontinuing HCQ.

Exacerbation of Darier disease with lithium therapy.

Darier disease is an autosomal dominant blistering disorder linked to mutation of the endoplasmic reticulum calcium pump, SERCA2, which compromises keratinocyte adhesion and differentiation. Beyond the typical keratotic and eroded skin lesions, patients with Darier disease often present with psychiatric co-morbidities. Herein, we present a biopsy-confirmed case of Darier disease in a patient with bipolar disorder, whose cutaneous disease dramatically worsened upon initiation of lithium therapy. In consultation with the patient's psychiatrist, lithium was tapered, leading to rapid improvement in her skin. This case highlights the potential for lithium to complicate management of Darier disease and underscores the need for dermatologists to collaborate with psychiatrists to optimize both cutaneous and mental health in patients.

CAR+ T-Cell Lymphoma Post Ciltacabtagene Autoleucel Therapy for Relapsed Refractory Multiple Myeloma

Introduction:Rareevents of T-cell lymphoma (TCL) derived from CAR-T cells (2 cases) have been reported in patients receiving nonviral piggyBac transposon-based CAR-T therapy (Micklethwaite et al, Blood, 2021). Ciltacabtagene autoleucel (cilta-cel) is an anti-BCMA CAR-T therapy produced via conventional lentiviral transduction. In the randomized, phase 3 CARTITUDE-4 study (NCT04181827), cilta-cel significantly improved PFS (HR=0.26) vs standard of care in lenalidomide-refractory patients with multiple myeloma and 1-3 prior lines of therapy. We present the clinicogenomic characterization of a CARTITUDE-4 patient who developed a CAR+ TCL post cilta-cel. Methods: Diagnostic and staging workup included biopsy analyses and FDG-PET scan. Presence of CAR+ cells in lymph node biopsy (LNB) was assessed by quantitative polymerase chain reaction (qPCR), in situ hybridization (ISH), and immunohistochemistry (IHC). Whole genome sequencing (WGS), transcriptome sequencing, whole exome sequencing (WES), T-cell receptor (TCR) sequencing, and genome-wide CAR integration analyses were conducted. Results:A 51 y/o male patient received cilta-cel; CAR+ T cells in blood peaked 14 d post-infusion (77 cells/μL) and decreased to 3 cells/μL at d 92 post-infusion, when he achieved stringent complete response (sCR) and MRD negativity at 10 -5. At 5 mo post-infusion, a relatively rapidly growing erythematous nasofacial plaque developed. TCL was diagnosed based on facial lesion biopsy showing an infiltrate of atypical T cells positive for CD2 and CD3 but negative for CD4, CD8, CD7, CD56, ALK, EBER-ISH, TdT, CD30, and cytotoxic T cell markers. FDG-PET showed bilateral FDG-avid cervical lymphadenopathy, with similar T cell infiltrate in submandibular LNB. qPCR and ISH/IHC revealed 90-100% of LNB cells to be CAR+. At d 162 post-infusion (after TCL diagnosis but before TCL-directed chemotherapy) CAR+ T cells in blood had re-expanded, independent of BCMA antigen, to 378 cells/μL. CAR integration analysis of LNB revealed a dominant insertion into the 3′UTR of PBX2 (91.1% of total reads from all integration sites), suggesting tumor monoclonality. TCR sequencing (1.8×10 -6 sensitivity) of LNB showed a monoclonal sequence in 91% of all T cells. Analysis of the drug product revealed the same unique TCR sequence from the monoclone at low frequency (~2×10 -6), suggesting the presence of this clone in apheresis material. WGS showed low overall mutational burden in the LNB (1.26 mutations/megabase) with 37 coding and 3286 non-coding variants, including 2 predicted loss-of-function TET2 mutations; a PTPRB truncation; and a focal duplication involving the 5′UTR to intron 16 of NFKB2. No dominant mutational signatures or gross copy number changes were observed. WES of the LNB indicated that a TET2 mutation (p.H1416R), which was not due to CAR insertion, was heterozygous and likely clonal. Targeted sequencing (0.5% sensitivity) of stored CD34+ cells and bone marrow aspirate collected from the patient 2 y earlier showed no abnormalities. Germline samples revealed the presence of a heterozygous JAK3 variant (p.V722I) that has been described as an activating variant, implicated in TCL, and detected in germline samples from patients with antigen-induced TCL (Blombery et al, Haematologica, 2016). The patient received CHOEP-21 (cyclophosphamide-doxorubicin-vincristine-prednisone-etoposide) and achieved metabolic CR but relapsed soon after treatment was stopped. Subsequent treatment with gemcitabine-dexamethasone-cisplatin-alemtuzumab was followed by consolidation with fludarabine plus melphalan and matched allogeneic stem cell transplant. He relapsed with cutaneous disease within 3 mo. Conclusions: To our knowledge, this is the first case of CAR+ TCL occurring after infusion of a CAR-T therapy produced via lentiviral transduction (cilta-cel). This rare malignancy was potentially driven by genetic mutations (e.g., TET2, NFKB2, PTPRB and/or JAK3), some of which may have existed in the form of a clone with malignant potential before cilta-cel manufacturing (e.g., TET2 p.H1416R and JAK3 p.V722I variants). A potential contributory role of the CAR insertion in the 3′ untranslated region of PBX2 to TCL development remains unclear and cannot be excluded at this time. Further investigation is needed to elucidate the differential contributions of these genomic factors to the etiology of this TCL case.

Herpes Zoster and COVID-19 Vaccination: A Narrative Review.

COVID-19 was a worldwide emergency, leading to a global health crisis, which completely revolutionized every aspect of human life. Several strategies were adopted to limit the spreading of the infection such as testing and contact tracing, quarantine and isolation, use of face mask, social distancing, lockdowns, travel restrictions, etc. Of these, vaccines were the most important measures to reduce the transmission of the virus and the severity of the infection, in order to overcome the pandemic. Fortunately, vaccination campaign was a success, showing to be efficient in controlling and preventing the COVID-19, reducing the risk of disease progression, hospitalization, and mortality. Monitoring and addressing vaccine-related adverse events have been essential for maintaining public confidence. Indeed, with the increasing number of vaccines administered, various cutaneous reactions have been reported, making dermatologists key players in their recognition and treatment. Particularly, several cutaneous diseases and cutaneous findings have been reported. Of note, also viral reactivations have been described following COVID-19 vaccination. Among these, varicella zoster virus (VZV) reactivation has been collected. Globally, an early diagnosis and an accurate treatment of herpes zoster (HZ) is mandatory to reduce possible complications. In this context, we conducted a review of the current literature investigating cases HZ following COVID-19 vaccination with the aim of understanding the possible causal correlation and underlying pathogenetic mechanisms to offer clinicians a wide perspective on VZV reactivation and COVID-19 vaccines.

Clinical Manifestations and Genomic Evaluation of Melioidosis Outbreak among Children after Sporting Event, Australia.

Melioidosis, caused by the environmental gram-negative bacterium Burkholderia pseudomallei, usually develops in adults with predisposing conditions and in Australia more commonly occurs during the monsoonal wet season. We report an outbreak of 7 cases of melioidosis in immunocompetent children in Australia. All the children had participated in a single-day sporting event during the dry season in a tropical region of Australia, and all had limited cutaneous disease. All case-patients had an adverse reaction to oral trimethoprim/sulfamethoxazole treatment, necessitating its discontinuation. We describe the clinical features, environmental sampling, genomic epidemiologic investigation, and public health response to the outbreak. Management of this outbreak shows the potential benefits of making melioidosis a notifiable disease. The approach used could also be used as a framework for similar outbreaks in the future.

Skin microbiome profile in people living with HIV/AIDS in Cameroon.

The presence of pathogens and the state of diseases, particularly skin diseases, may alter the composition of human skin microbiome. HIV infection has been reported to impair gut microbiome that leads to severe consequences. However, with cutaneous manifestations, that can be life-threatening, due to the opportunistic pathogens, little is known whether HIV infection might influence the skin microbiome and affect the skin homeostasis. This study catalogued the profile of skin microbiome of healthy Cameroonians, at three different skin sites, and compared them to the HIV-infected individuals. Taking advantage on the use of molecular assay coupled with next-generation sequencing, this study revealed that alpha-diversity of the skin microbiome was higher and beta-diversity was altered significantly in the HIV-infected Cameroonians than in the healthy ones. The relative abundance of skin microbes such as Micrococcus and Kocuria species was higher and Cutibacterium species was significantly lower in HIV-infected people, indicating an early change in the human skin microbiome in response to the HIV infection. This phenotypical shift was not related to the number of CD4 T cell count thus the cause remains to be identified. Overall, these data may offer an important lead on the role of skin microbiome in the determination of cutaneous disease state and the discovery of safe pharmacological preparations to treat microbial-related skin disorders.

Diffuse skin lesions in a patient with systemic lupus erythematosus: A case report

Systemic lupus erythematous (SLE) is a persistent autoimmune disease with systemic and life- threatening manifestations, in which cutaneous disease is the second most common manifestation, after joint inflammation. Skin lesions in SLE is originally divided into two groups: LE-specific lesions and LE-nonspecific lesions. The term “LE-specific lesions” includes 3 distinct categorizes: Acute cutaneous lupus erythematosus (ACLE), subacute cutaneous lupus erythematosus (SCLE) and chronic cutaneous lupus erythematosus (CCLE) [4]. By another method of classification, specific skin lesions can also be classified as localized or generalized lesions. The most common localized lesion is malar, or butterfly rash, which is reported in 20-60% of patients with SLE. In comparision to localized lesions, generalized lesions, which are indiscriminately referred to as lupus maculopapular rash, are relatively rare. This form of lesion is characterized by well-demarcated erythematous macules and/or papules located on the extensor side of limbs, sparing the knuckles. In this article, we report a case of a female patient having generalized cutaneous lesions. She was initially diagnosed with SLE and received treatment at Department of Allergy, Center of Dermato-Venerology and Allergy, 108 Military Central Hospital.

Clinicopathological characteristics of cutaneous complications following COVID-19 vaccination: A case series.

Several vaccine-related cutaneous adverse events occurred following the widespread use of vaccines to prevent coronavirus disease 2019 (COVID-19). This case series reports 25 patients with de novo or accentuated dermatologic conditions after receiving the Sinopharm, Sputnik V, AstraZeneca, or BIV1-CovIran vaccine in Iran. Twenty-five eligible patients with a mean age of 46.80 years were investigated. The cutaneous adverse events included pityriasis rosea, zoster, viral exanthema, urticaria, bullous pemphigoid, pemphigus vulgaris, and acute generalized exanthematous pustulosis. The manifestations appeared 14.45 ± 6.98 and 20.79 ± 22.18 days following injection of the first and second doses of COVID-19 vaccines, respectively. All patients experienced new cases of cutaneous disease other than two who developed flare-ups of lichen planus and psoriasis. Several cutaneous reactions, ranging from allergic events to skin diseases, have been reported following the injection of COVID-19 vaccines. Focal injection-site reactions are the most common cutaneous adverse events; however, de-novo skin diseases and a flare-up of preexisting cutaneous disorders have also been described. Although many cases of COVID-19 vaccine-related cutaneous diseases have been published, our zoster/lichen planus and AGEP cases after vaccination are interesting. A more detailed understanding of cutaneous adverse events following COVID-19 vaccination will facilitate better diagnosis and management.

The Mind Body Connection in Dermatologic Conditions: A Literature Review.

Psychodermatology pertains to the relationship between the skin and brain. This review aims to summarize the evidence of the mind body connection in four psychophysiological conditions: rosacea, atopic dermatitis (AD), acne vulgaris (AV), and psoriasis. A literature search was conducted using several English language databases. All four conditions share similar psychiatric co-morbidities, including but not limited to anxiety, depression, and suicidality. In rosacea, the upregulation of transient receptor potential vanilloid type 1, Toll like receptor 2, and Th17 cells releases downstream products that are simultaneously implicated in mood disorders. Stress exacerbates AV through the hypothalamic-pituitary-adrenal (HPA) system, which alters functioning of sebocytes and Cutibacterium acnes. In AD and psoriasis, the HPA axis influences Th1, Th2, Th22, and Th1, Th17 immune mediated responses, respectively. This leads to the secretion of pro-inflammatory cytokines which are also involved in the pathogenesis of anxiety and depression. Neurotransmitters implicated in mental illness, such as gamma-aminobutyric acid and serotonin, may also play a role in the development of AD and psoriasis. The management of cutaneous disease may mitigate psychological distress, and future research may show the corollary to also be true.
