Efficacy of topical tacrolimus 0.1% in active plaque morphea: randomized, double-blind, emollient-controlled pilot study

Consensus statement on the diagnosis and treatment of sclerosing diseases of the skin, Part 1: Localized scleroderma, systemic sclerosis and overlap syndromes

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present consensus provides an update to the 2017 European Dermatology Forum Guidelines, focusing on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, updated strategies for the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this consensus provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes.

Best clinical practice in the treatment of juvenile systemic sclerosis: expert panel guidance - the result of the International Hamburg Consensus Meeting December 2022

INTRODUCTION

Juvenile systemic sclerosis (jSSc) is an orphan disease with a prevalence of 3 in 1,000,000 children. Currently there is only one consensus treatment guideline concerning skin, pulmonary and vascular involvement for jSSc, the jSSc SHARE (Single Hub and Access point for pediatric Rheumatology in Europe) initiative, which was based on data procured up to 2014. Therefore, an update of these guidelines, with a more recent literature and expert experience, and extension of the guidance to more aspects of the disease is needed.

AREAS COVERED

Treatment options were reviewed, and opinions were provided for most facets of jSSc including general management, some of which differs from adult systemic sclerosis, such as the use of corticosteroids, and specific organ involvement, such as skin, musculoskeletal, pulmonary, and gastroenterology.

EXPERT OPINION

We are suggesting the treat to target strategy to treat early to prevent cumulative disease damage in jSSc. Conclusions are derived from both expert opinion and available literature, which is mostly based on adult systemic sclerosis (aSSc), given shared pathophysiology, extrapolation of results from aSSc studies was judged reasonable.

S2k guideline: Diagnosis and therapy of localized scleroderma

The updated S2k guideline deals with the diagnosis and therapy of localized scleroderma (LoS). LoS represents a spectrum of sclerotic skin diseases in which, depending on the subtype and localisation, structures such as adipose tissue, muscles, joints, and bones may also be affected. Involvement of internal organs or progression to systemic sclerosis does not occur. LoS can be classified into four main forms: limited, generalized, linear, and mixed forms, with some additional subtypes. For cases of limited skin involvement, the guideline primarily recommends therapy with topical corticosteroids. UV therapy can also be recommended. In subtypes with severe skin or musculoskeletal involvement, systemic therapy with methotrexate is recommended. During the active phase of the disease, systemic glucocorticosteroids can be used additionally. In cases of methotrexate and steroid refractory courses, contraindications, or intolerance, mycophenolate mofetil, mycophenolic acid, or abatacept can be considered as second-line systemic therapies. In the case of linear LoS, autologous adipose-derived stem cell transplantation can also be performed for correcting soft tissue defects.

S2k‐Leitlinie: Diagnostik und Therapie der zirkumskripten Sklerodermie

Die vorliegende aktualisierte S2k‐Leitlinie befasst sich mit der Diagnostik und der Therapie der zirkumskripten Sklerodermie (ZS). Diese umfasst ein Spektrum sklerotischer Erkrankungen der Haut mit, je nach Subtyp und Lokalisation, möglicher Beteiligung von hautnahen Strukturen wie Fettgewebe, Muskulatur, Gelenke und Knochen. Ein Befall innerer Organe oder ein Übergang in eine systemische Sklerodermie treten nicht auf. Eingeteilt werden kann die ZS in die vier Hauptformen der limitierten, generalisierten, linearen und gemischten Form. Teilweise existieren weitere Unterformen. Bei limitiertem Hautbefall empfiehlt die Leitlinie primär eine Therapie mit topischen Kortikosteroiden. Eine UV‐Therapie kann ebenfalls sinnvoll sein. Bei Subtypen mit schwerem Hautbefall oder muskuloskelettalem Befall wird eine systemische Therapie mit Methotrexat empfohlen. In der aktiven Phase der Erkrankung können ergänzend systemische Glukokortikosteroide eingesetzt werden. Bei MTX‐ und Steroid‐refraktären Verläufen, Kontraindikation oder Unverträglichkeit sollten Mycophenolat‐Mofetil, Mycophenolsäure oder Abatacept als Systemtherapie der zweiten Wahl eingesetzt werden. Bei einer linearen ZS kann zudem eine autologe Fettstammzelltransplantation zur Korrektur von Weichteildefekten erfolgen.

Recent Advances in Treatment of Systemic Sclerosis and Morphea

Systemic sclerosis (SSc) and morphea are autoimmune sclerosing diseases that cause significant morbidity, and in the case of SSc, mortality. The pathogenesis of both SSc and morphea share vascular dysfunction, auto-reactive T cells and Th2-associated cytokines, such as interleukin 4, and overproduction of transforming growth factor beta (TGFβ). TGFβ stimulates fibroblast collagen and extra-cellular matrix production. Although morphea and SSc have similar pathogenic pathways and histological findings, they are distinct diseases. Recent advances in treatment of morphea, skin sclerosis in SSc, and interstitial lung disease in SSc are focused on targeting known pathogenic pathways.

Intraoral Involvement in Linear Scleroderma En Coup De Sabre: A Case Report

Localized scleroderma is a connective tissue disorder that causes excessive collagen deposition and skin fibrosis. It can be subdivided into morphea and linear scleroderma. En coup de sabre (ECDS) is a rare variant of linear scleroderma typically found among children. It is usually treated with methotrexate and corticotherapy in addition to folic acid supplements. To date, few cases of ECDS have been reported with oral involvement. This case report discusses a seven-year-old girl with linear scleroderma ECDS who was referred to the dental clinic to evaluate muscular hypotrophy on the floor of the mouth. Upon clinical and radiographic examination, the patient had hypotrophied mylohyoid muscle, reduced alveolar bone height on the affected side, and a deviated midline to the affected side as well. Furthermore, the patient was classified as having a high caries risk. After consultation with the primary physician regarding treatment modalities and options, the patient completed her comprehensive dental treatment at the Dental Department at King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia.

[Juvenile localized scleroderma]

Juvenile scleroderma, often referred to as juvenile localized scleroderma or "morphea", is a rare inflammatory disease of the skin and skin-related structures, accompanied by local sclerosis and tissue fibrosis. Depending on the clinical manifestation, four different subtypes can be defined: limited, generalized, linear, and mixed. To prevent possible sequelae of the disease, the diagnosis should be made as early as possible and therapy should be initiated at specialized centers in multiprofessional pediatric and dermatologic collaboration. In this review, we present the main clinical, laboratory, and therapeutic characteristics of juvenile localized scleroderma and summarize recommendations.

Immunologic and nonimmunologic sclerodermal skin conditions - review

Scleroderma-like cutaneous lesions have been found in many pathological conditions and they have the clinical appearance of sclerotic or scleroatrophic lesions. Affected skin biopsies described histopathological changes similar to those of scleroderma located strictly on the skin or those of systemic sclerosis. These skin lesions can be found in inflammatory diseases with autoimmune substrate (generalized morphea, chronic graft versus host disease, eosinophilic fasciitis), tissue storage diseases (scleredema, scleromyxedema, nephrogenyc systemic fibrosis, systemic amyloidosis), metabolic diseases (porphyrya cutanea tarda, phenylketonuria, hypothyroidism, scleredema diabeticorum), progeroid syndromes. Given the multiple etiologies of sclerodermal lesions, a correct differential diagnosis is necessary to establish the appropriate treatment.

Use of a novel indentometer to evaluate skin stiffness in healthy and diseased human skin

BACKGROUND

Mechanical behavior of the skin can be evaluated by different non-invasive methods. In this study, we applied a new measurement device based on indentometry to determine the skin mechanical properties in healthy individuals and in patients with systemic sclerosis (SSc).

MATERIAL AND METHODS

Three studies were performed. Study 1 included 100 healthy individuals (46 male and 54 female) divided into four age groups with mean ages of 21.5, 28.9, 51.2, and 69.3 years, respectively. Test sites were located on the center of the forehead and the middle of both volar forearms. Study 2 included 16 healthy individuals (two males and 14 females). Test sites were on both volar forearms. Measurements were made before and after the application of Vaseline and emulsion with 12% urea. Study 3 included 20 patients (one male and 19 females) with SSc and 60 age-matched healthy individuals (23 males and 37 females). Test sites were on the center of the forehead and the middle of both volar forearms. Skin stiffness was measured with skin Indentometer IDM 800 (Courage + Khazaka, Cologne, Germany) equipped with two probes with pin diameters of 3 and 5 mm, respectively. The stiffer the skin, the less deep the displacement by the indenter. The smaller the diameter, the deeper the pin will go into the skin when using the same force. In addition, the Corneometer CM 820 (Courage + Khazaka) was used to determine epidermal water content in study 2.

RESULTS

Indentometric (IDM) values of healthy subjects measured with both probes were lower on the forehead compared to volar forearms. There was no significant difference between both forearms. In all age groups, the IDM values on the male forearms were lower than on the female forearms whereas there was no significant difference on the forehead. In both sex and on all test locations a significant positive correlation between age and IDM values measured with both probes was observed. There was a significant positive correlation between IDM values measured with both probes. The application of moisturizers induced significant changes in epidermal water content whereas the IDM values remained unchanged. At both the forehead and volar forearms, the IDM values in patients with SSc were significantly lower compared to the healthy control skin.

CONCLUSION

The non-invasive indentometric method used can successfully distinguish the changes in normal skin mechanical properties related to age, sex, and anatomical location, as well as in patients with SSc. The method is not appropriate to study the changes related to epidermal hydration.

Development and Validation of the Morphea Activity Measure in Patients With Pediatric Morphea

Importance

Morphea is an insidious inflammatory disorder of the skin and deeper tissues. Determining disease activity is challenging yet important to medical decision-making and patient outcomes.

Objective

To develop and validate a scoring tool, the Morphea Activity Measure (MAM), to evaluate morphea disease activity of any type or severity that is easy to use in clinical and research settings.

Design, Setting, and Participants

This pilot diagnostic study was conducted from September 9, 2019, to March 6, 2020, in 2 phases: development and validation. During the development phase, 14 morphea experts (dermatologists and pediatric dermatologists) used a Delphi consensus method to determine items that would be included in the MAM. The validation phase included 8 investigators who evaluated the tool in collaboration with 14 patients with pediatric morphea (recruited from a referral center [Medical College of Wisconsin]) during a 1-day in-person meeting on March 6, 2020.

Main Outcomes and Measures

During the development phase, online survey items were evaluated by experts in morphea using a Likert scale (score range, 0-10, with 0 indicating not important and 10 indicating very important); agreement was defined as a median score of 7.0 or higher, disagreement as a median score of 3.9 or lower, and no consensus as a median score of 4.0 to 6.9. During the validation phase, reliability (interrater and intrarater agreement using intraclass correlation coefficients), validity (using the content validity index and κ statistics as well as correlations with the modified Localized Scleroderma Severity Index and the Physician Global Assessment of Activity using Spearman ρ coefficients), and viability (using qualitative interviews of investigators who used the MAM tool) were evaluated. Descriptive statistics were used for quantitative variables. Data on race and ethnicity categories were collected but not analyzed because skin color was more relevant for the purposes of this study.

Results

Among 14 survey respondents during the development phase, 9 (64.3%) were pediatric dermatologists and 5 (35.7%) were dermatologists. After 2 rounds, a final tool was developed comprising 10 items that experts agreed were indicative of morphea activity (new lesion in the past 3 months, enlarging lesion in the past 3 months, linear lesion developing progressive atrophy in the past 3 months, erythema, violaceous rim or color, warmth to the touch, induration, white-yellow or waxy appearance, shiny white wrinkling, and body surface area). The validation phase was conducted with 14 patients (median age, 14.5 years [range, 8.0-18.0 years]; 8 [57.1%] female), 2 dermatologists, and 6 pediatric dermatologists. Interrater and intrarater agreement for MAM total scores was good, with intraclass correlation coefficients of 0.844 (95% CI, 0.681-0.942) for interrater agreement and 0.856 (95% CI, 0.791-0.901) for intrarater agreement. Correlations between the MAM and the modified Localized Scleroderma Severity Index (Spearman ρ = 0.747; P < .001) and the MAM and the Physician Global Assessment of Activity (Spearman ρ = 0.729; P < .001) were moderately strong. In qualitative interviews, evaluators agreed that the tool was easy to use, measured morphea disease activity at a single time point, and should be responsive to changes in morphea disease activity over multiple time points.

Conclusions and Relevance

In this study, the MAM was found to be a reliable, valid, and viable tool to measure pediatric morphea activity. Further testing to assess validity in adults and responsiveness to change is needed.

Morphea: The 2023 update

Morphea, also known as localized scleroderma, is a chronic inflammatory connective tissue disorder with variable clinical presentations, that affects both adults and children. It is characterized by inflammation and fibrosis of the skin and underlying soft tissue, in certain cases even of the surrounding structures such as fascia, muscle, bone and central nervous system. While the etiology is still unknown, many factors may contribute to disease development, including genetic predisposition, vascular dysregulation, T_H1/T_H2 imbalance with chemokines and cytokines associated with interferon-γ and profibrotic pathways as well as certain environmental factors. Since the disease may progress to permanent cosmetic and functional sequelae, it is crucial to properly assess the disease activity and to initiate promptly the adequate treatment, thus preventing subsequent damage. The mainstay of treatment is based on corticosteroids and methotrexate. These, however, are limited by their toxicity, especially if applied long-term. Furthermore, corticosteroids and methotrexate often do not sufficiently control the disease and/or the frequent relapses of morphea. This review presents the current understanding of morphea by discussing its epidemiology, diagnosis, management and prognosis. In addition, it will describe recent pathogenetic findings, thus proposing potential novel targets for therapeutic development in morphea.

Diagnosis and Management of Cutaneous Manifestations of Autoimmune Connective Tissue Diseases

The cutaneous features of autoimmune connective tissue disease pose a unique challenge to patients and clinicians managing these conditions. In this review, we outline the key elements of diagnosis and treatment of cutaneous lupus erythematosus, dermatomyositis, systemic sclerosis, and morphea. This article also aims to present an update on gold standard as well as new and emerging therapies for these conditions. Overall, dermatologists can play a key role in diagnosing and treating autoimmune connective tissue diseases and this review intends to provide an up-to-date toolkit to guide clinical dermatologists in this endeavor.

Pediatric morphea state-of-the-art literature review: Reframing morphea as a systemic disease

Pediatric morphea is an inflammatory, fibrosing dermatologic disorder. Although morphea may be localized to the skin and subcutaneous tissues, differentiating it from systemic sclerosis, there is increasing evidence that morphea is a manifestation of a systemic inflammatory process, with the potential to involve many organ systems. Given the potential risk for irreversible sequelae, pediatric morphea should be treated early and aggressively. Long-term disease monitoring is essential.

Plasticity of Treg and imbalance of Treg/Th17 cells in patients with systemic sclerosis modified by FK506

To determine the effects of Tacrolimus (FK506) on Treg cells and subpopulations in SSc patients and assess the ability of FK506 to modify the immune imbalance of Treg/Th17 cells. We analyzed PBMC from five SSc patients and six healthy control by flow cytometry after cultured with 0, 0.1, 1, or 10 ng/ml FK506 in vitro. The number of Treg cells decreased in SSc patients treated with FK506. The number of FrI cells were decreased in SSc following FK506 treatment. The drug did increase the frequency of FrII/Treg cells, but not FrII cells. However, FK506 significantly decreased FrIII in both SSc patients and controls. FK506 clearly decreased the numbers of Th17 cells and FoxP3⁺IL-17⁺ cells. The proliferation capacity of cells was also inhibited by FK506, which had a greater effect on FoxP3^- cells than FoxP3⁺ cells. FK506 did inhibit the proliferation of FrIII cells, but not FrI or FrII cells. Our study provides that FK506 reduced the number of FoxP3^low CD45RA^- T cells (FrIII) by inhibiting its proliferation. Therefore, FK506 modifies Treg cells and the immune imbalance between Tregs and Th17 cells in SSc patients.

Clinical Treatment Options in Scleroderma: Recommendations and Comprehensive Review

There are two major clinical subsets of scleroderma: (i) systemic sclerosis (SSc) is a complex systemic autoimmune disorder characterized by inflammation, vasculopathy, and excessive fibrosis of the skin and multiple internal organs and (ii) localized scleroderma (LoS), also known as morphea, is confined to the skin and/or subcutaneous tissues resulting in collagen deposition and subsequent fibrosis. SSc is rare but is associated with significant morbidity and mortality compared with other rheumatic diseases. Fatal outcomes in SSc often originate from organ complications of the disease, such as lung fibrosis, pulmonary artery hypertension (PAH), and scleroderma renal crisis (SRC). Current treatment modalities in SSc have focused on targeting vascular damage, fibrosis, and regulation of inflammation as well as autoimmune responses. Some drugs previously used in an attempt to suppress fibrosis, like D-penicillamine (D-Pen) or colchicine, have been disappointing in clinical practice despite anecdotal evidence of their advantages. Some canonical medications, including glucocorticoids, immunosuppressants, and vasodilators, have had some success in treating various manifestations in SSc patients. Increasing evidence suggests that some biologic agents targeting collagen, cytokines, and cell surface molecules might have promising therapeutic effects in SSc. In recent years, hematopoietic stem cell transplantation (HSCT), mostly autologous, has made great progress as a promising treatment option in severe and refractory SSc. Due to the complexity and heterogeneity of SSc, there are currently no optimal treatments for all aspects of the disease. As for LoS, local skin-targeted therapy is generally used, including topical application of glucocorticoids or other immunomodulatory ointments and ultraviolet (UV) irradiation. In addition, systemic immunosuppressants are also utilized in several forms of LoS. Here, we comprehensively discuss current treatment options for scleroderma, encompassing old, new, and future potential treatment options. In addition, we summarize data from new clinical trials that have the potential to modify the disease process and improve long-term outcomes in SSc.

Paediatric morphoea: a holistic review. Part 2: diagnosis, measures of disease activity, management and natural history

Paediatric morphoea is a debilitating fibrosing disorder of uncertain aetiology, affecting the skin and subcutaneous tissues. Defining optimum management strategies in paediatric morphoea remains an ongoing challenge, owing to the varied presentations and a relative paucity of paediatric-specific studies. We performed a literature search on PubMed, MEDLINE and Google Scholar, using keywords such as 'pediatric morphea', 'juvenile localised scleroderma' and 'juvenile systemic sclerosis'. Relevant studies, including randomized trials, reviews of standard current guidelines and original research articles, were selected and results analysed before summarizing them. In Part 1 of this review, we described the epidemiology, aetiopathogenesis and clinical classification; in this part, we discuss the diagnosis, markers of disease activity, management and natural history in paediatric morphoea.

Update on Management of Morphea (Localized Scleroderma) in Children

Juvenile localized scleroderma (morphea) is the predominant scleroderma in childhood which affects the skin and may extend to the underlying fascia, muscle, joints and bone. The assessment of activity and damage can be done with a validated instrument like LoSCAT. Disease classified as “low severity” which includes superficial plaque morphea can be treated with topical mid potent- potent steroids, tacrolimus, calcipotriol or imiquimod in combination with phototherapy. Methotrexate is recommended for linear, deep and generalized morphea. Steroids are effective in the early inflammatory stage and used in combination with methotrexate. Methotrexate is continued for at least 12 months after adequate response is achieved. Mycophenolate mofetil is given in cases where methotrexate is contraindicated or for those who do not respond to methotrexate. There are also reports of improvement of disease with ciclosporine and hydroxychloroquine. In severe cases, recalcitrant to standard therapy there may be a role for biologics, JAK inhibitors, and IVIG. Supportive measures like physiotherapy and psychiatric counseling are also important in the management of morphea. Orthopedic surgery and other measures like autologous fat transfer may be advocated once the disease is inactive.

A retrospective study: Impact of consensus treatment plans on systemic therapy of pediatric morphea

BACKGROUND

Morphea is an inflammatory and fibrosing condition that affects the skin and subcutaneous structures. Morphea is managed by dermatologists, rheumatologists, or both. Prior studies have suggested there is significant variability in approach to treatment. In 2012, the Childhood Arthritis and Rheumatology Research Alliance (CARRA) published consensus treatment plans (CTPs) for pediatric morphea to develop more standardized treatment plans for patients requiring systemic therapy. We aimed to assess whether the publication of CTPs has impacted care of patients with morphea at our institution.

METHODS

Data were collected via a retrospective review of medical records of 61 pediatric patients diagnosed with morphea at Seattle Children's Hospital (SCH) from January 1, 2005, to December 12,2017.

RESULTS

Prior to the publication of CTPs, 2 out of 24 patients (8.3%) were treated with a regimen that matched a subsequent CTP. After publication of CTPs, 29 out of 37 patients (78.4%) were treated with a regimen that matched a CTP (P < 0.001). A subanalysis was performed to assess the number of patients who needed second- or third-line therapies. Of those who followed a CTP therapy plan (n = 26), 3 patients (11.5%) needed a second-line therapy compared with 11 patients (44%) in the no-CTP followed group (n = 25), (P = 0.012).

CONCLUSIONS

The publication of CTPs led to a significant change in treatment approach for patients with morphea requiring systemic therapy at SCH. Patients treated with one of the treatment plans recommended by the CTPs were less likely to need second-line systemic therapy.

Off-Label Use of Topical Calcineurin Inhibitors in Dermatologic Disorders

Off-label prescribing is a common practice in dermatology, particularly when uncommon dermatologic diseases have limited or no approved treatment options. Topical calcineurin inhibitors are approved for the treatment of eczema, and their anti-inflammatory, immunomodulatory, and steroid-sparing effects make them an attractive therapeutic option for a wide variety of other dermatologic diseases. This review summarizes and qualifies the available evidence supporting the clinical effectiveness of tacrolimus ointment and pimecrolimus cream in non-eczema indications. There is high-quality evidence supporting the effectiveness of topical calcineurin inhibitors in multiple dermatological disorders including vitiligo; psoriasis of the face, folds, and genitals; seborrheic dermatitis; chronic hand dermatitis; contact dermatitis; oral lichen planus; lichen sclerosus; morphea; and cutaneous lupus erythematosus. Lower-quality evidence suggests they may be considered as an option in many other cutaneous disorders.

Interventions for morphea

BACKGROUND

Morphea (morphoea) is an immune-mediated disease in which excess synthesis and deposition of collagen in the skin and underlying connective tissues results in hardened cutaneous areas. Morphea has different clinical features according to the subtype and stage of evolution of the disease. There is currently no consensus on optimal interventions for morphea.

OBJECTIVES

To assess the effects of treatments for people with any form of morphea.

SEARCH METHODS

We searched the following databases up to July 2018: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, LILACS, and five trial registers. We checked the reference lists of included studies for further references to relevant randomised controlled trials.

SELECTION CRITERIA

Randomised controlled trials of topical, intralesional, or systemic treatments (isolated or combined) in anyone who has been clinically diagnosed by a medical practitioner with any form of morphea. Eligible controls were placebo, no intervention, any other treatment, or different doses or duration of a treatment.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. The primary outcomes were global improvement of disease activity or damage assessed by a medical practitioner or by participants, and adverse effects. Secondary outcomes were improvement of disease activity and improvement of disease damage. We used GRADE to assess the quality of the evidence for each outcome.

MAIN RESULTS

We included 14 trials, with a total of 429 randomised participants, aged between 3 and 76 years. There were juvenile and adult participants; over half were female, and the majority had circumscribed morphea, followed by linear scleroderma. The settings of the studies (where described) included a dermatologic centre, a national laboratory centre, paediatric rheumatology and dermatology centres, and a university hospital or medical centre.The studies evaluated heterogenous therapies for different types of morphea, covering a wide range of comparisons. We were unable to conduct any meta-analyses. Seven studies investigated topical medications, two evaluated intralesional medications, and five investigated systemic medications. The study duration ranged from seven weeks to 15 months from baseline.We present here results for our primary outcomes for our four key comparisons. All of these results are based on low-quality evidence.The included studies were at high risk of performance, detection, attrition, and reporting bias.Global improvement of disease activity or damage after treatment may be higher with oral methotrexate (15 mg/m², maximum 20 mg, once a week, for 12 months or until disease flare) plus oral prednisone (1 mg/kg a day, maximum of 50 mg, in a single morning dose, for three months, and one month with gradually decreased dose until discontinuation) than with placebo plus oral prednisone in children and adolescents with active morphea (linear scleroderma, generalised morphea or mixed morphea: linear and circumscribed) (risk ratio (RR) 2.31, 95% confidence interval (CI) 1.20 to 4.45; number needed to treat for an additional beneficial outcome (NNTB) 3; 1 randomised controlled trial (RCT); 70 participants, all juvenile). This outcome was measured 12 months from the start of treatment or until flare of the disease. Data were not available separately for each morphea type. There may be little or no difference in the number of participants experiencing at least one adverse event with oral methotrexate (26/46) or placebo (11/24) (RR 1.23, 95% CI 0.75 to 2.04; 1 RCT; 70 participants assessed during the 12-month follow-up). Adverse events related to methotrexate included alopecia, nausea, headache, fatigue and hepatotoxicity, whilst adverse events related to prednisone (given in both groups) included weight gain (more than 5% of body weight) and striae rubrae.One three-armed RCT compared the following treatments: medium-dose (50 J/cm²) UVA-1; low-dose (20 J/cm²) UVA-1; and narrowband UVB phototherapy. There may be little or no difference between treatments in global improvement of disease activity or damage, as assessed through the modified skin score (where high values represent a worse outcome): medium-dose UVA-1 phototherapy versus low-dose UVA-1 group: MD 1.60, 95% CI -1.70 to 4.90 (44 participants); narrowband UVB phototherapy versus medium-dose UVA-1 group: MD -1.70, 95% CI -5.27 to 1.87 (35 participants); and narrowband UVB versus low-dose UVA-1 group: MD -0.10, 95% CI -2.49 to 2.29 (45 participants). This RCT included children and adults with active morphea (circumscribed morphea, linear scleroderma (with trunk/limb variant and head variant), generalised morphea, or mixed morphea), who received phototherapy five times a week, for eight weeks. Outcomes were measured at eight weeks from the start of treatment.Safety data, measured throughout treatment, from the same RCT (62 participants) showed that treatment with UVA-1 phototherapy may cause mild tanning compared to narrowband UVB: narrowband UVB versus medium-dose UVA-1: RR 0.03, 95% CI 0.00 to 0.42; 35 participants; narrowband UVB versus low-dose UVA-1: RR 0.03, 95% CI 0.00 to 0.41; 45 participants. However, there may be no difference in the number of participants reporting mild tanning when comparing medium and low dose UVA-1 phototherapy (RR 1.00, 95% CI 0.91 to 1.10; 44 participants). Transient erythema was reported in three participants with narrowband UVB and no participants in the low- or medium-dose UVA-1 groups.

AUTHORS' CONCLUSIONS

Compared to placebo plus oral prednisone, oral methotrexate plus oral prednisone may improve disease activity or damage in juvenile active morphea (linear scleroderma, generalised morphea or mixed morphea: linear and circumscribed), but there may be a slightly increased chance of experiencing at least one adverse event.When medium-dose UVA-1 (50 J/cm²), low-dose UVA-1 (20 J/cm²), and narrowband UVB were compared against each other in treating children and adults with active morphea (circumscribed morphea, linear scleroderma, generalised morphea and mixed morphea), there may be little or no difference between these treatments on global improvement of disease activity or damage. UVA-1 phototherapy may cause more mild tanning than narrowband UVB, but there may be no difference between medium- and low-dose UVA-1 phototherapy. These results are based on low-quality evidence.Limitations of data and analyses include risk of bias and imprecision (small number of participants or events and wide confidence intervals). We encourage multicentre RCTs to increase sample size and evaluate, with validated tools, different treatment responses according to the subtypes of morphea and age groups.

Cutaneous Manifestations of Scleroderma and Scleroderma-Like Disorders: a Comprehensive Review

Scleroderma refers to an autoimmune connective tissue fibrosing disease, including three different subsets: localized scleroderma, limited cutaneous systemic sclerosis, and diffuse cutaneous systemic sclerosis with divergent patterns of organ involvement, autoantibody profiles, management, and prognostic implications. Although systemic sclerosis is considered the disease prototype that causes cutaneous sclerosis, there are many other conditions that can mimic and be confused with SSc. They can be classified into immune-mediated/inflammatory, immune-mediated/inflammatory with abnormal deposit (mucinoses), genetic, drug-induced and toxic, metabolic, panniculitis/vascular, and (para)neoplastic disorders according to clinico-pathological and pathogenetic correlations. This article reviews the clinical presentation with emphasis on cutaneous disease, etiopathogenesis, diagnosis, and treatment options available for the different forms of scleroderma firstly and for scleroderma-like disorders, including scleromyxedema, scleredema, nephrogenic systemic fibrosis, eosinophilic fasciitis, chronic graft-versus-host disease, porphyria cutanea tarda, diabetic stiff-hand syndrome (diabetic cheiroartropathy), and other minor forms. This latter group of conditions, termed also scleroderma mimics, sclerodermiform diseases, or pseudosclerodermas, shares the common thread of skin thickening but presents with distinct cutaneous manifestations, skin histology, and systemic implications or disease associations, differentiating each entity from the others and from scleroderma. The lack of Raynaud's phenomenon, capillaroscopic abnormalities, or scleroderma-specific autoantibodies is also important diagnostic clues. As cutaneous involvement is the earliest, most frequent and characteristic manifestation of scleroderma and sclerodermoid disorders, dermatologists are often the first-line doctors who must be able to promptly recognize skin symptoms to provide the affected patient a correct diagnosis and appropriate management.

Magnetic Resonance Imaging Evaluation in Patients with Linear Morphea Treated with Methotrexate and High-Dose Corticosteroid

Background

Morphea is an inflammatory disease of the connective tissue that may lead to thickening and hardening of the skin due to fibrosis. The aim of this study was to document magnetic resonance imaging (MRI) changes in patients with linear morphea who were treated with methotrexate (MTX) and high-dose corticosteroid.

Methods

This study was conducted on 33 patients from the outpatient's dermatology clinic of our institute, who fulfilled the inclusion criteria. Patients received 15 mg/week of MTX and monthly pulses of methylprednisolone for three days in six months. The effectiveness of the treatment was evaluated by MRI, modified LS skin severity index (mLoSSI), and localized scleroderma damage index (LoSDI).

Results

All parameters of mLoSSI and LoSDI including erythema, skin thickness, new lesion/lesion extension, dermal atrophy, subcutaneous atrophy, and dyspigmentation were also noticeably improved after treatment. Subcutaneous fat enhancement was the most common finding in MRI. MRI scores were significantly associated with clinical markers both before and after the treatment with the exception of skin thickness and new lesion/lesion extension which were not associated with MRI scores before and after the treatment, respectively.

Limitations

The lack of correlative laboratory disease activity markers, control group, and clearly defined criteria to judge the MRI changes.

Conclusion

MRI could be a promising tool for the assessment of musculoskeletal and dermal involvement and also monitoring treatment response in patients with morphea.

Diagnostic criteria, severity classification and guidelines of localized scleroderma

We established diagnostic criteria and severity classification of localized scleroderma because there is no established diagnostic criteria or widely accepted severity classification of the disease. Also, there has been no clinical guideline for localized scleroderma, so we established its clinical guideline ahead of all over the world. In particular, the clinical guideline was established by clinical questions based on evidence-based medicine according to the New Minds Clinical Practice Guideline Creation Manual (version 1.0). We aimed to make the guideline easy to use and reliable based on the newest evidence, and to present guidance as specific as possible for various clinical problems in treatment of localized scleroderma.

Discordance of pediatric morphea treatment by pediatric dermatologists

BACKGROUND/OBJECTIVES

Studies describing treatment efficacy in pediatric morphea are lacking. Subspecialists have reached no consensus on how to optimally treat pediatric morphea. The objective of the current study was to describe the most common treatment practices of pediatric dermatologists worldwide who care for children with morphea.

METHODS

A survey regarding topical treatment practices of pediatric morphea, with representative case-based scenarios, was distributed to pediatric dermatologists and results were tallied.

RESULTS

The survey response rate was 13.4%, with 110 respondents in the final analysis. The majority of respondents agreed on red violaceous rim (99%), increased local warmth (75%), raised borders (69%), and dermal thickening (64%) as signs of disease activity. Respondents had less agreement on sclerotic lesions (41%), scaling (43%), dyspigmentation (19%), and atrophy (13%) as signs of disease activity. Ninety-two percent of respondents used primary therapy or monotherapy with topical medications, including 45% in linear morphea of the limbs and 37% in linear morphea of the head or neck. High-potency topical corticosteroids were most commonly used (80%), although respondents did not agree on specific regimens. Sixteen different treatment regimens were selected as first-line therapy for one case scenario of active disease.

CONCLUSION

The survey found large variation in how pediatric dermatologists treat pediatric morphea. Consensus treatment guidelines developed by pediatric dermatologists and pediatric rheumatologists are urgently needed regarding the efficacy of therapies for pediatric morphea. Prospective studies of treatment efficacy in pediatric morphea are urgently needed as well.

European Dermatology Forum S1-guideline on the diagnosis and treatment of sclerosing diseases of the skin, Part 1: localized scleroderma, systemic sclerosis and overlap syndromes

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present guideline focuses on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, current strategies in the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this guideline provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes of systemic sclerosis with diseases of the rheumatological spectrum.

Morphea and Eosinophilic Fasciitis: An Update

Morphea, also known as localized scleroderma, encompasses a group of idiopathic sclerotic skin diseases. The spectrum ranges from relatively mild phenotypes, which generally cause few problems besides local discomfort and visible disfigurement, to subtypes with severe complications such as joint contractures and limb length discrepancies. Eosinophilic fasciitis (EF, Shulman syndrome) is often regarded as belonging to the severe end of the morphea spectrum. The exact driving mechanisms behind morphea and EF pathogenesis remain to be elucidated. However, extensive extracellular matrix formation and autoimmune dysfunction are thought to be key pathogenic processes. Likewise, these processes are considered essential in systemic sclerosis (SSc) pathogenesis. In addition, similarities in clinical presentation between morphea and SSc have led to many theories about their relatedness. Importantly, morphea may be differentiated from SSc based on absence of sclerodactyly, Raynaud’s phenomenon, and nailfold capillary changes. The diagnosis of morphea is often based on characteristic clinical findings. Histopathological evaluation of skin biopsies and laboratory tests are not necessary in the majority of morphea cases. However, full-thickness skin biopsies, containing fascia and muscle tissue, are required for the diagnosis of EF. Monitoring of disease activity and damage, especially of subcutaneous involvement, is one of the most challenging aspects of morphea care. Therefore, data harmonization is crucial for optimizing standard care and for comparability of study results. Recently, the localized scleroderma cutaneous assessment tool (LoSCAT) has been developed and validated for morphea. The LoSCAT is currently the most widely reported outcome measure for morphea. Care providers should take disease subtype, degree of activity, depth of involvement, and quality-of-life impairments into account when initiating treatment. In most patients with circumscribed superficial subtypes, treatment with topical therapies suffices. In more widespread disease, UVA1 phototherapy or systemic treatment with methotrexate (MTX), with or without a systemic corticosteroid combination, should be initiated. Disappointingly, few alternatives for MTX have been described and additional research is still needed to optimize treatment for these debilitating conditions. In this review, we present a state-of-the-art flow chart that guides care providers in the treatment of morphea and EF.

Morphea - selected local treatment methods and their effectiveness

Localised scleroderma is an uncommon connective tissue disease of multifactorial aetiology occurring in the paediatric and adult population. It is relatively difficult to conduct any research on the subject of this disease entity treatment due to the low number of patients suffering from morphea, a tendency of the disease to remit spontaneously, and not yet well recognised aetiology. Hence, there has been developed no causal treatment of well-proven effectiveness, and schedules of symptomatic therapy are not yet clearly determined. The paper depicts most widely used topical treatment methods in morphea therapy, which due to minor risk of systemic adverse effects seem to be a beneficial therapeutic alternative. The main aim of this article was to analyse different topical treatment options used in localised scleroderma therapy and to indicate the most appropriate, safe, and effective one.

German guidelines for the diagnosis and therapy of localized scleroderma

Localized scleroderma designates a heterogeneous group of sclerotic skin disorders. Depending on the subtype, severity, and site affected, adjacent structures such as adipose tissue, muscles, joints, and bones may be involved. This is an update of the existing German AWMF (Association of the Scientific Medical Societies in Germany) guidelines (classification: S2k). These guidelines provide an overview of the definition, epidemiology, classification, pathogenesis, laboratory workup, histopathology, clinical scoring systems, as well as imaging and device-based workup of localized scleroderma. Moreover, consensus-based recommendations are given on the management of localized scleroderma depending on its clinical subtype. Treatment recommendations are presented in a therapeutic algorithm. No financial support was given by any pharmaceutical company. The guidelines are valid until July 2019.

Cyclosporine Reduces Sclerosis in Morphea: A Retrospective Study in 12 Patients and a Literature Review

BACKGROUND

The treatment of severe morphea is challenging, and treatment experience concerning the use of immunosuppressive agents for this condition is limited.

OBJECTIVE

The purpose of this study is to analyze the use of cyclosporine, its tolerability, and its effect on skin sclerosis.

MATERIALS AND METHODS

Patients with severe morphea who underwent treatment with cyclosporine were studied retrospectively.

RESULTS

Five of 12 patients with morphea showed complete remission and 6 patients had partial remission at the end of therapy (9-46 months, median 14) under a median cyclosporine dose of 2.4 mg/kg. The mean affected body surface area fell from 50% (2-80, median 65) to 17% (0-40, median 18). Side effects were hypertension, elevated transaminases, cholesterol, and weight gain.

CONCLUSION

Cyclosporine can be effective in morphea. The side effects were reversible. However, the duration of treatment with cyclosporine is limited because of its potential permanent side effects. Prospective placebo-controlled studies are needed to establish the superiority of cyclosporine over other immunosuppressive drugs in this setting.

Localized scleroderma: a review

Localized scleroderma (LoS) comprises a heterogeneous spectrum of fibrotic diseases that primarily affect the skin with inflammation and skin thickening. The extent of skin involvement and manifestation at extra-cutaneous structures characterizes the specific subset. Fat tissue, fascia, and sometimes muscle, and bones might be involved, and in rare cases the central nervous or ocular system.

A worldwide accepted classification system for LoS is still lacking. The latest guidelines have proposed a distinction of limited, generalized, linear, deep, and mixed types. The exact pathophysiology of LoS is not fully understood yet, but it is thought that an externally triggered release of pro-inflammatory cytokines leads to a dysregulation of the connective tissue metabolism.

LoS is diagnosed according to typical clinical features. Further diagnostic procedures are helpful to characterize the subtype and to define the extent of inflammation and fibrosis.

Due to the heterogeneity of LoS, therapeutic strategies should always be selected depending on the respective subtype. The stage of tissue inflammation and sclerosis has to be considered. Treatment options such as topical corticosteroids, calcipotriol, and calcineurin inhibitors as well as phototherapy are well established. In subsets with severe wide-spread skin manifestation and/or extra-cutaneous involvement, methotrexate monotherapy or a combination of methotrexate and systemic corticosteroids need to be considered. Physical treatment should always be added to the topical and systemic treatment to prevent significant disabilities due to LoS. This article provides an updated review on the epidemiology, pathophysiology, clinical classification and treatment options for patients suffering from LoS.

Autoimmune collagen vascular diseases: Kids are not just little people

Morphea, dermatomyositis (DM), and discoid lupus erythematosus (DLE) are autoimmune collagen vascular diseases that can present at any age. In all three of these diseases, the tenants of diagnosis and treatment are largely the same in both children and adults, with a few notable differences. Children with morphea are more likely to present with the linear subtype and have a higher incidence of extracutaneous manifestations. Children often need early aggressive systemic treatment to try to prevent long-term sequelae of morphea. In DM, adult disease has a clear association with malignancy that is not seen in children. Adults have a higher rate of pulmonary involvement and increased mortality, whereas calcinosis is more common in juvenile DM. DLE in adults is generally considered to have a low rate of progression from discoid lesions alone to systemic lupus erythematosus (SLE). DLE is less common in children, but several studies have suggested a higher rate of progression from DLE to SLE in children compared with adults.

Current and future direction in the management of scleroderma

Scleroderma is a heterogeneous disease with a complex etiology. As more information is gained about the underlying mechanisms and the improved classifications of scleroderma subtypes, treatments can be better personalized. Improving scleroderma patients' early diagnosis before end organ manifestations occur should improve clinical trial design and outcomes. Two recently FDA-approved antifibrotics for idiopathic pulmonary fibrosis may be effective treatments in patients with pulmonary fibrosis secondary to scleroderma after further investigation. The potential impact of Nanobiotechnology in improving the efficacy and safety of existing antifibrotics and immunomodulators might present an exciting new approach in the management of scleroderma.

Systemic sclerosis and localized scleroderma--current concepts and novel targets for therapy

Systemic sclerosis (SSc) is a chronic autoimmune disease with a high morbidity and mortality. Skin and organ fibrosis are key manifestations of SSc, for which no generally accepted therapy is available. Thus, there is a high unmet need for novel anti-fibrotic therapeutic strategies in SSc. At the same time, important progress has been made in the identification and characterization of potential molecular targets in fibrotic diseases over the recent years. In this review, we have selected four targeted therapies, which are tested in clinical trials in SSc, for in depths discussion of their preclinical characterization. Soluble guanylate cyclase (sGC) stimulators such as riociguat might target both vascular remodeling and tissue fibrosis. Blockade of interleukin-6 might be particularly promising for early inflammatory stages of SSc. Inhibition of serotonin receptor 2b signaling links platelet activation to tissue fibrosis. Targeting simultaneously multiple key molecules with the multityrosine kinase-inhibitor nintedanib might be a promising approach in complex fibrotic diseases such as SSc, in which many partially independent pathways are activated. Herein, we also give a state of the art overview of the current classification, clinical presentation, diagnostic approach, and treatment options of localized scleroderma. Finally, we discuss whether the novel targeted therapies currently tested in SSc could be used for localized scleroderma.

A rare case of juvenile localised scleroderma with intra-oral and dental involvement

Juvenile localised scleroderma is a rare childhood disorder of the immune system and connective tissue with unknown etiology. There are different types of localised scleroderma, including linear scleroderma (where the lesion appears as a line or streak) and plaque or circumscribed morphea (where the lesion appears as a roundish lesion). The present report describes the case of a 10-year-old girl, who presented with a history of linear scleroderma with nose, oral and dental involvement, and outlines the diagnosis of the case based on the clinical presentation, pathology, X-ray and cone beam computed tomography images. The treatment strategy that was selected for the patient is additionally discussed.

Localized scleroderma: clinical spectrum and therapeutic update

Scleroderma is a rare connective tissue disease that is manifested by cutaneous sclerosis and variable systemic involvement. Two categories of scleroderma are known: systemic sclerosis, characterized by cutaneous sclerosis and visceral involvement, and localized scleroderma or morphea which classically presents benign and self-limited evolution and is confined to the skin and/or underlying tissues. Localized scleroderma is a rare disease of unknown etiology. Recent studies show that the localized form may affect internal organs and have variable morbidity. Treatment should be started very early, before complications occur due to the high morbidity of localized scleroderma. In this review, we report the most important aspects and particularities in the treatment of patients diagnosed with localized scleroderma.

Pirfenidone gel in patients with localized scleroderma: a phase II study

Introduction

Localized scleroderma is an inflammatory disease in its first stages and a fibrotic process in later stages, principally mediated by the transforming growth factor β. To date, there is no standard treatment. The objective of this study was to determine the effectiveness and safety of 8% pirfenidone gel in patients with localized scleroderma.

Methods

This was an open phase II clinical trial that included 12 patients. Treatment with pirfenidone was indicated, three times daily for 6 months. Patients were evaluated clinically with the modified Localized Scleroderma Skin Severity Index (mLoSSI), as well with a durometer and histologically using hematoxylin and eosin stain and Masson’s trichrome stain.

Results

The baseline mLoSSI average scores were 5.83 ± 4.80 vs. 0.83 ± 1.75 (P = 0.002) at 6 months. The initial durometer induration of the scleroderma plaques was 35.79 ± 9.10 vs. 32.47 ± 8.97 at 6 months (P = 0.05). We observed histopathological improvement with respect to epidermal atrophy, inflammation, dermal or adipose tissue fibrosis and annex atrophy from 12.25 ± 3.25 to 9.75 ± 4.35 (P = 0.032). The 8% pirfenidone gel application was well tolerated, and no side effects were detected.

Conclusions

This is the first study on the therapeutic use of pirfenidone gel in localized scleroderma. It acts on both the inflammatory and the fibrotic phases. Considering its effectiveness, good safety profile and the advantage of topical application, pirfenidone is a treatment option in this condition.

Short- and long-term outcome of linear morphoea in children

BACKGROUND

Linear morphoea (LM) is a rare fibrosing disorder of the limbs or the face that may cause functional disability and severe aesthetic sequelae. Despite a wide range of therapeutics reported for LM, there is currently a lack of consensus on the optimal therapy. Little is known about the long-term outcome of this disease.

OBJECTIVES

To describe the short- and long-term outcome of a large series of patients with LM acquired in childhood.

METHODS

A retrospective chart review of 52 paediatric patients with LM seen in our centre during a 20-year span (1990-2010) and a telephone survey in 2011 to assess the long-term outcome of these patients.

RESULTS

Limbs were affected twice as often as the face, with a higher proportion of female patients. Stabilization was obtained after a mean disease duration of 5·4 years. Patients sometimes experienced long stretches of disease quiescence followed by reactivation; 31% of patients reported active disease after 10 years. All but one patient had aesthetic sequelae, and 38% had functional limitations. The effectiveness of methotrexate and systemic corticosteroids was apparent in the short term.

CONCLUSIONS

LM needs prolonged monitoring as the disease can have very long periods of quiescence followed by reactivation. The combination of methotrexate and systemic corticosteroids was effective in the early stages of the disease but did not seem to prevent long-standing active disease or relapse in the long term.

Update on the classification and treatment of localized scleroderma

Morphea or localized scleroderma is a distinctive inflammatory disease that leads to sclerosis of the skin and subcutaneous tissues. It comprises a number of subtypes differentiated according to their clinical presentation and the structure of the skin and underlying tissues involved in the fibrotic process. However, classification is difficult because the boundaries between the different types of morphea are blurred and different entities frequently overlap. The main subtypes are plaque morphea, linear scleroderma, generalized morphea, and pansclerotic morphea. With certain exceptions, the disorder does not have serious systemic repercussions, but it can cause considerable morbidity. In the case of lesions affecting the head, neurological and ocular complications may occur. There is no really effective and universal treatment so it is important to make a correct assessment of the extent and severity of the disease before deciding on a treatment approach.

New developments in juvenile systemic and localized scleroderma

Juvenile localized scleroderma (jLS) and juvenile systemic sclerosis (jSS) are both orphan diseases, with jLS around 10 times more frequent than jSS. In recent years the time gap between the appearance of symptoms and diagnosis has become significantly shorter. This review focuses on the new classifications of jSS and jLS, and on the developments and adaptations of the outcome measures for certain organ involvements whereby progress has been made regarding pediatric patients.

Localized scleroderma: a clinical study at a single center in Korea

OBJECTIVE

Localized scleroderma (morphea) is a rare autoimmune disease limited to the skin, characterized by cutaneous fibrosing and obstructive vasculopathy. Localized scleroderma may invade into the subcutaneous fat layer and cause permanent functional disability. Because of its rarity, there have been few clinical surveys of patients with localized scleroderma in Korea. The aim of this study was to elucidate the clinical presentation, serological data, and clinical outcomes of localized scleroderma.

METHODS

This was a retrospective survey conducted by reviewing available medical records during a 7 year-period from 2004 to 2010 in a single medical center in Jeju Island, South Korea. In total 43 patients with localized scleroderma were included.

RESULTS

Localized scleroderma occurred primarily in females (female to male ratio 2.6 : 1.0). Most patients were between 10 and 29 years of age and the mean age at diagnosis was 26.2 years. Plaque (51.2%) and linear morphea (37.2%) were most common. No case was associated with systemic scleroderma (systemic sclerosis). The most common site of plaque morphea was the trunk (47.8%). In the linear type, the most common site was head-neck (52.9%). Fluorescent antinuclear antibody was positive in 23.3% of all cases. Treatment included systemic corticosteroids, colchicine, anti-malarial agents, D-penicillamine or intralesional triamcinolone injection. Clinical improvement, including significant and partial response, was seen in only 62.8% of treated patients.

CONCLUSION

Localized scleroderma is a chronic inflammatory condition confined to the skin. In order to exclude other conditions, thorough history taking, physical examination, serologic studies and histopathologic examinations should be conducted.
