A case of multiple autoimmune syndrome comprising autoimmune thyroid disease, vitiligo, morphea, and lichen sclerosus.

Multiple autoimmune syndrome is a manifestation of polyautoimmunity with the co-occurrence of three or more autoimmune diseases in a single patient. We report a unique case of a 55-year-old female patient that presented with four autoimmune diseases: autoimmune thyroid disease, vitiligo, morphea, and lichen sclerosus. She was evaluated for progression of morphea and lichen sclerosus, and we confirmed histopathological overlapping of these two diseases in the same lesion. We discuss the increasing prevalence of autoimmune diseases and similar case reports on dermatological polyautoimmunity.

Unusual overlap of systemic sclerosis with Takayasu arteritis.

Overlap syndromes are diseases that meet the criteria of two or more rheumatic diseases. In this case report, a woman in her 20s presented with a constellation of symptoms, including skin thickening, Raynaud's phenomenon, hypertension, absent pulse in both lower limbs with bilateral renal artery bruit. The antinuclear antibody profile revealed Scl-70 positivity. CT thorax identified early interstitial lung disease, and nailfold capillaroscopy showed severe capillary loss. CT angiogram features were suggestive of Takayasu arteritis. Notably, there have been only four documented cases of systemic sclerosis coexisting with Takayasu arteritis, highlighting the rarity of this overlap syndrome. The diagnosis of overlap syndrome was made after a thorough history recording and clinical examination. In the presence of bilateral renal artery stenosis, managing the scleroderma renal crisis may be challenging . This patient received treatment with mycophenolate mofetil and oral corticosteroids, aiming to address both systemic sclerosis and Takayasu arteritis effectively.

Nephrotic syndrome due to focal segmental glomerulosclerosis complicating scleroderma: a case report.

BACKGROUND: Systemic scleroderma (SSc) is an insidious autoimmune connective tissue disorder with multiorgan involvement. Renal involvement is one of the important causes of morbidity and mortality in scleroderma; however, nephrotic syndrome is reported rarely in association with SSc. We present a patient with SSc who developed focal segmental glomerulosclerosis (FSGS) as a complication of scleroderma. CASE PRESENTATION: A 59 year old Caucasian female patient, with a known history of diffuse systemic sclerosis from 8 years, presented to our clinic with symptoms of anasarca and weight gain. Her physical examination was unremarkable except for periorbital and extremity edema. Her biochemistry assessment revealed decreased serum albumin levels and elevated serum creatinine levels. A renal biopsy was performed, which showed histopathological patterns of FSGS type of nephrotic syndrome. After administration of high doses of steroid and rituximab in the course of her treatment for 6 months, her symptoms and proteinuria were improved without the occurrence of scleroderma renal crises. CONCLUSION: SSc is a complex multisystemic autoimmune disorder. SRC is the most prominent renal involvement in SSc, but other renal pathologies may also occur. Each patient should be precisely investigated since managing these renal conditions can differ significantly. Nephrotic syndrome is a rare complication of SSc, which could be managed with prompt diagnosis and steroid administration.

Ocular and eyelid involvement in collagen vascular diseases. Part II. Dermatomyositis, scleroderma, and sarcoidosis.

Collagen vascular disease is a heterogeneous group of autoimmune diseases that affect multiple organ systems. Sjögren syndrome, dermatomyositis, scleroderma, systemic lupus erythematosus, and sarcoidosis are collagen vascular diseases that often present with characteristic cutaneous manifestations. Although less known, various ocular manifestations that affect both external and internal structures of the eye can also be seen in these conditions. Multidisciplinary management between dermatologists and ophthalmologists is essential in the early diagnosis and management of collagen vascular diseases affecting both the skin and eye. In part II of our series, we discuss the ocular manifestations, diagnosis, and therapeutic options of dermatomyositis, scleroderma, and sarcoidosis.

A Historic Cohort Analysis of Radiographic and Serologic Findings in Patients With Scleroderma and Interstitial Lung Disease.

BACKGROUND/OBJECTIVE: Few studies have investigated associations between rheumatologic serology patterns and different interstitial lung disease (ILD) patterns. METHODS: We present novel findings of a historic cohort study (n = 454) with data collected from 2011 to 2021 within our hospital system. In this institutional review board-approved study, data regarding rheumatologic serologies and ILD patterns were noted based on chart review in patients with scleroderma. The Kruskal-Wallis rank sum and χ2 tests were used for statistical analysis. RESULTS: Results showed a statistically significant association between anti-U1 snRNP with lymphoid interstitial pneumonia, which has not been previously described. CONCLUSIONS: We demonstrated novel serologic associations with ILD patterns, which have important clinical implications. More robust and high-powered studies are needed to elucidate the role of serologic testing and their association with ILD phenotypes.

Morphea as an isotopic response to pigmented purpuric dermatosis and lichen striatus.

Morphea is an uncommon inflammatory and fibrosing disorder that has a polymorphous clinical presentation. We report two cases of morphea developing as an isotopic response after a preceding benign skin disease, accompanied by a review of the literature. This case series highlights the importance of return to care recommendations for benign skin conditions such lichen striatus and pigmented purpuric dermatoses due to the rare possibility of subsequent morphea development.

Distinct Scleroderma Autoantibody Profiles Stratify Patients for Cancer Risk at Scleroderma Onset and During the Disease Course.

OBJECTIVES: We examined whether an array of scleroderma autoantibodies associates with risk of cancer and could be useful tools for risk stratification. METHODS: Scleroderma cancer cases and scleroderma controls without cancer from the Johns Hopkins Scleroderma Center and the University of Pittsburgh Scleroderma Center were studied. Sera were assayed by Lineblot and enzyme-linked immunosorbent assay (ELISA) for autoantibodies against centromere, topoisomerase 1, RNA polymerase (POLR) 3, PM/Scl, Th/To, NOR90, U3 RNP, Ku, Ro52, U1RNP, and RNPC3. Logistic regression models were constructed to examine whether distinct autoantibodies associated with overall cancer at any time and cancer-associated scleroderma (cancer occurring three years before and after scleroderma onset). The effects of having more than one autoantibody on cancer were further examined using random forest analysis. RESULTS: A total of 676 cases and 687 controls were studied. After adjusting for relevant covariates, anti-POLR3 (odds ratio [OR] 1.47, 95% confidence interval [CI] 1.03-2.11) and monospecific anti-Ro52 (OR 2.19, 95% CI 1.29-3.74) were associated with an increased overall cancer risk, whereas anticentromere (OR 0.69, 95% CI 0.51-0.93) and anti-U1RNP (OR 0.63, 95% CI 0.43-0.93) were associated with lower risk. When examining risk of cancer-associated scleroderma, these immune responses remained associated with increased or decreased risk: anti-POLR3 (OR 2.28, 95% CI 1.33-3.91), monospecific anti-Ro52 (OR 2.58, 95% CI 1.05-6.30), anticentromere (OR 0.39, 95% CI 0.20-0.74), and anti-U1RNP (OR 0.32, 95% CI 0.11-0.93). Anti-Ro52 plus anti-U1RNP or anti-Th/To was associated with decreased cancer risk compared with anti-Ro52 alone. CONCLUSIONS: These data suggest that five distinct scleroderma immune responses, alone or in combination, may be useful tools to stratify the risk of cancer for scleroderma patients. Further study examining cancer risk in autoantibody subgroups relative to the general population is warranted.

Capturing the Range of Disease Involvement in Localized Scleroderma: The Localized Scleroderma Total Severity Scale.

OBJECTIVE: Juvenile localized scleroderma (jLS) is a chronic autoimmune disease commonly associated with poor outcomes, including contractures, hemiatrophy, uveitis, and seizures. Despite improvements in treatment, >25% of patients with jLS have functional impairment. To improve patient evaluation, our workgroup developed the Localized scleroderma Total Severity Scale (LoTSS), an overall disease severity measure. METHODS: LoTSS was developed as a weighted measure by a consensus process involving literature review, surveys, case vignettes, and multicriteria decision analysis. Feasibility was assessed in larger Childhood Arthritis and Rheumatology Research Alliance groups. Construct validity with physician assessment and inter-rater reliability was assessed using case vignettes. Additional evaluation was performed in a prospective patient cohort initiating treatment. RESULTS: LoTSS severity items were organized into modules that reflect jLS disease patterns, with modules for skin, extracutaneous, and craniofacial manifestations. Construct validity of LoTSS was supported by a strong positive correlation with the Physician Global Assessment (PGA) of severity and damage and weak positive correlation with PGA-Activity, as expected. LoTSS was responsive, with a small effect size identified. Moderate-to-excellent inter-rater reliability was demonstrated. LoTSS was able to discriminate between patient subsets, with higher scores identified in those with greater disease burden and functional limitation. CONCLUSION: We developed a new LS measure for assessing cutaneous and extracutaneous severity and have shown it to be reliable, valid, and responsive. LoTSS is the first measure that assesses and scores all the major extracutaneous manifestations in LS. Our findings suggest LoTSS could aid assessment and management of patients and facilitate outcome evaluation in treatment studies.

BULGARIAN PATIENT WITH ATROPHODERMA OF PASINI AND PIERINI- DESCRIPTION OF A CASE AND SHORT UPDATE.

Atrophoderma of Pasini and Pierini is a rare, considered benign, skin disease characterized by single or multiple asymptomatic atrophic plaques. Lesions can occur everywhere on the body with the trunk being the most often reported affected site. It appears in the second or third decade of life and affects mostly the female population, with male to female ratio of 1:6, commonly of white European descent. Different risk factors were described in the literature - genetic predisposition, infections with Epstein-Barr virus, varicella zoster and Borrelia burgdorferi, vaccinations, local trauma and more. Since the pandemic with COVID-19, skin manifestations after the viral infection with COVID-19 were reported. After a thorough search of the existing medical literature, we believe, we present the first case of a rapid progression of Atrophoderma of Pasini and Pierini after COVID-19 infection. Due to its similarity to morphea in some aspects, the condition is often misdiagnosed, and the proper treatment is often delayed. Sometimes the dilemma "Is it atrophoderma Pasini-Pierini or is it in fact morphea?" stays, but the exact histopathological verification and the "diagnostic clues" which can be used during the examination stage, are usually enough to diagnose the condition. We present a 63-year-old female with a rapid progression of atrophoderma of Pasini and Pierini after a COVID-19 infection. The lesion that she presented with was single, asymptomatic, with central hypopigmentation and slight atrophy, with a smooth, shiny surface and ivory color, and peripheral hyperpigmentation, measured 18x5cm, without the presence of perilesional erythema. The patient was initially diagnosed clinically with localized scleroderma (morphea) and treated with hydroxychloroquine 200 mg once daily for a 5-year period without improvement. Years later two biopsies from different lesional sites were taken, resulting in absence of sclerosis and dermal atrophy, but - reduction in the thickness of the dermis with fragmentation and hyalinization of collagen fibers forming a parallel orientation, dilated vascular vessels of small caliber and reduced number of skin appendages, confirming the diagnosis of atrophoderma Pasini-Pierini. The patient's therapy was switched to methotrexate with good therapeutic response. Often, the two conditions - morphea and atrophoderma of Pasini and Pierini can be mistaken due to its clinical similarity and sometimes coexistence. Therefore, we will shortly review the existing literature with key points on the similarities and differences.

Morphea after Silicone Implants.

Dear Editor, Silicone is a hydrophobic polymer containing silicon. Silicon is an essential compound of soft tissue proteoglycans. Reports about morphea and other autoimmune connective tissue disorders in association with silicone implants have stimulated the discussion of a possible link between the two, such as immunological cross-reactivity of silicone and connective tissue components (1). A number of case reports suggested a possible link to adjuvant autoimmune syndrome (2), morphea of the breast (3-5), and systemic scleroderma (6-8), among others. One study measured tissue silicon levels in women with silicone breast implants with and without symptoms or signs and compared these data with women who had either a saline breast implant or no augmentation at all. The authors detected higher levels of silicon in capsular tissue of patients with silicone implants, independent of the presence of any symptoms or signs (9,10). The conclusion was that there is no evidence of an association between silicone implants and autoimmune connective tissue disorders. Three other clinical trials investigating the role of silicone implants and induction of autoimmune connective tissue disorders also failed to find an association between the two (11-13). We report the case of a 32-year-old female patient who developed morphea of the breasts after silicone implants for augmentation after risk-reducing mastectomy for Cowden syndrome. She presented with pronounced capsule fibrosis of the implants. With a delay of several years, an ill-defined slightly hyperpigmented area developed on the breasts and ventral chest (Figure 1). The lesion was analyzed by dermoscopy (Figure 2), which found mild erythema, reduced vessels, and white areas (ill-defined dull white globules, fibrotic beams). A skin biopsy was taken. Histopathological analysis showed a normal epidermal layer, minor papillary edema, and some vascular ectasias in the papillary dermis and upper corium (Figure 3). There was mild perivascular inflammatory infiltrate of the deep dermal vascular plexus, composed of lymphocytes and monocytes with some plasma cells (Figure 4). Elastic fibers seemed unaffected (Figure 5). The diagnosis of an early morphea of the edematous-inflammatory stage was established. Treatment with topical corticosteroids and UVB-311 nm irradiation was recommended. Morphea of the breasts is an uncommon disorder. It may occur after radiotherapy of breast cancer, after silicone augmentation, or without any known cause (14-16). A meta-analysis found an increased risk for morphea/scleroderma, with a relative risk between 1.30 to 2.13 and an odds ratio for case control studies of 1.68 (17). The US FDA Breast Implant Approval Study evaluated almost 100,000 female patients with breast implants. An increased risk of Sjögren's syndrome, scleroderma, and rheumatoid arthritis was reported (18). We could not find any reference of an association between capsular fibrosis and morphea of the breast, although both represent fibrotic disorders. In conclusion, it seems possible that there is a link between morphea of the breast and chest as described herein and silicone breast implants, which is supported by epidemiological studies. However, a direct causal relationship is hard to demonstrate with a single case.

Stiff skin syndrome: a clinicopathological study of 31 cases.

BACKGROUND: Stiff skin syndrome (SSS) is a rare disease characterized by sclerosis of the skin. Cases of both widespread and segmental SSS have been reported. OBJECTIVES: To report the clinical and histopathological characteristics of a large series of SSS. MATERIALS & METHODS: We retrospectively analysed the clinical and histopathological characteristics of widespread and segmental SSS collected from a dermatology department. We also compared histopathology between segmental SSS and morphea. RESULTS: Thirty-one cases, including three widespread SSS and 28 segmental SSS, were collected. Skin lesions of widespread SSS generally showed skin sclerosis concentrating over the lumbar, buttocks, thighs, proximal part of limbs, and shoulders with specific abnormal gait and posture. Skin lesions of segmental SSS generally showed sclerotic plaques involving the thigh, lumbar area and buttocks, associated with hypertrichosis, hyperpigmentation and a cobblestone appearance. Segmental SSS did not typically cause joint limitation or serious physical discomfort. Histopathologically, SSS showed proliferation of fibroblasts and sclerosis of collagen in the dermis or subcutaneous tissue. Compared with morphea, SSS showed more prominent proliferation of fibroblasts and completely lacked lymphocyte infiltration. CONCLUSION: Segmental SSS represents the major variant of SSS. Histopathologically, SSS shows proliferation of fibroblasts, sclerosis and an absence of inflammation.

Presenting characteristics and progression of pediatric-onset morphea: Interim analysis of a prospective registry.

Morphea is a rare fibrosing disorder with a highly variable disease course, which can complicate management. Here, we present a prospective cohort study describing the current treatments used in the management of pediatric-onset morphea and assessing responses to systemic and topical therapies. Most patients demonstrated inactive disease by 1 year, regardless of treatment, though recurrences were common in our cohort overall (39%). Our results support the need for continuous monitoring of all children with morphea following the completion of treatment, including topical treatment, due to high rates of disease relapse.

UVEAL EFFUSION ASSOCIATED WITH LOCALIZED SCLERODERMA BECAUSE OF SCLERAL FIBROSIS.

BACKGROUND/PURPOSE: To report a case of uveal effusion associated with localized scleroderma because of scleral collagen fibrosis. Partial-thickness sclerectomy treatment was successful in acquiring the resolution of the uveal effusion. METHODS: Case report. RESULTS: A 44-year-old Chinese woman with known localized scleroderma visited the retinal clinic complaining of insidious onset blurring of vision in both eyes for 8 months. The best-corrected visual acuity was 20/200. Ophthalmoscopy revealed apparent inferior bullous serous retinal detachments in the right eye. Optical coherence tomography showed subretinal fluid and folds of the retinal pigment epithelium layer in both eyes. B-scan ultrasonographic image of the right eye confirmed a 360-degree serous retinal detachment in the right eye accompanied with increased thickness of the ocular wall. Ultrasound biomicroscopy of the anterior segment detected a shallow ciliary body detachment in the right eye. Fluorescein angiography and indocyanine green angiography demonstrated the leopard-spot pattern in all phases. Partial-thickness sclerectomy treatment was successful in acquiring the resolution of the uveal effusion. Histopathologic examinations of the sclera flaps revealed scleral collagen fibrosis. CONCLUSION: This clinicopathologic report first describes a patient with localized scleroderma and scleral collagen fibrosis, resulting in uveal effusion that responded to partial-thickness sclerectomy.

Renal involvement in systemic sclerosis.

Systemic sclerosis is a rare autoimmune vasculopathy associated with dysregulated innate and adaptive immunity that leads to generalized systemic fibrosis. Renal involvement occurs in a significant proportion of systemic sclerosis patients, and is associated with worse outcome. Scleroderma renal crisis (SRC) is the most studied and feared renal complication described in systemic sclerosis. However, with the emergence of ACE inhibitors and better management, the mortality rate of SRC has significantly decreased. Renal disease in systemic sclerosis offers a wide array of differential diagnoses that may be challenging for the clinician. The spectrum of renal manifestations in systemic sclerosis ranges from an isolated decrease in glomerular filtration rate, increased intrarenal arterial stiffness, and isolated proteinuria due to SRC to more rare manifestations such as association with antiphospholipid antibody nephropathy and ANCA-associated vasculitis. The changes observed in the kidneys in systemic sclerosis are thought to be due to a complex interplay of various factors, including renal vasculopathy, as well as the involvement of the complement system, vasoactive mediators such as endothelin-1, autoimmunity, prothrombotic and profibrotic cytokines, among others. This literature review aims to provide an overview of the main renal manifestations in systemic sclerosis by discussing the most recent epidemiological and pathophysiological data available and the challenges for clinicians in making a diagnosis of renal disease in patients with systemic sclerosis.

Systemic sclerosis following COVID-19 infection with recurrent corticosteroid-induced scleroderma renal crisis.

Systemic sclerosis is a complex multisystem connective tissue disease resulting in fibrosis of the skin and internal organs. Exposure to corticosteroids can trigger scleroderma renal crisis, a life-threatening complication of the disease. Autoimmune disease following infection with COVID-19 is being increasingly recognised. The mechanisms of post-COVID-19 autoimmunity are likely multifactorial, involving immune dysregulation, molecular mimicry and the development of cross-reactive antibodies. There are currently only two reported cases of systemic sclerosis occurring post-COVID-19 infection.We present the case of a female patient who developed systemic sclerosis post-COVID-19 infection. Following exposure to corticosteroids, the patient developed scleroderma renal crisis complicated by thrombotic microangiopathy, seizures and acute renal failure. Despite an antibody profile not typically associated with renal crisis (anti-topoisomerase positive, anti-RNA-polymerase III negative), the patient developed recurrent renal crisis with repeated exposure to corticosteroid therapy, highlighting the risk of steroid use in all patients with systemic sclerosis.
