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.

[The useful forehead, the impaired forehead, but the forehead repaired!] / Le front utilisé, le front traumatisé, mais le front réparé !

The forehead, although sometimes hidden by a fringe, is a major region of the face revealing many expressions such as fatigue, surprise, concern, anger… In reconstructive surgery, the forehead is frequently used as a donor site. This article looks at three aspects: the used, traumatised and repaired forehead. The forehead, with its high-quality hairless skin and proximity to the noble structures of the face, is a central donor site. The forehead flap is commonly used for nasal reconstruction, with several variations to meet different needs. Other pedicled flaps, such as the supra-eyebrow flap and the crane flaps, are also used for various facial reconstructions. The forehead can be affected by trauma, burns, vascular lesions and skin tumours. We are particularly interested "en coup de sabre" linear scleroderma, an autoimmune disease that causes cutaneous and subcutaneous fibrosis, sometimes associated with Parry Romberg syndrome. In addition, lesions of the temporal branch of the facial nerve lead to muscular paralysis, affecting the aesthetics and function of the frontal region. Precise knowledge of the anatomy of the nerve pathway is crucial to avoid iatrogenic lesions. The entire arsenal of reconstructive surgery is useful for repairing the forehead. Controlled wound healing, tension suturing and the use of local flaps are key techniques for repairing the forehead. Tension sutures are particularly effective for small losses of substance, and their orientation depends on the location. Advancement, rotation and transposition flaps are used for larger losses of substance. Skin grafts, although less aesthetic, are sometimes necessary. Skin expansion, although socially restrictive, is used to treat congenital giant nevi and increase the surface area of forehead flaps.

Measuring asymmetry in facial morphea via 3-dimensional stereophotogrammetry.

BACKGROUND: Objectively determining tissue loss in craniofacial morphea is challenging. However, 3-dimensional (3D) stereophotogrammetry is a noninvasive modality that may be a useful adjunct. OBJECTIVE: To prospectively evaluate 3D stereophotogrammetry in the assessment of craniofacial linear morphea. METHODS: Participants underwent clinical, quality-of-life, and 3D-stereophotogrammetry assessments. Traditional photographs and 3D-stereophotogrammetry images were rated as mild, moderate, or severe by 2 experts and 2 nonexperts. In addition, interrater and intrarater reliability (on delayed rescoring) were calculated. RESULTS: Of 23 patients with craniofacial morphea, 3D stereophotogrammetry detected pathologic asymmetry in 14 (20.6%) patients. Providers rated patients as more severely affected when using 3D stereophotogrammetry versus when using traditional photographs (19% severe on 3D stereophotogrammetry vs 0% severe on traditional photographs, P = .004). Qualitative ratings of both traditional and 3D images showed high inter- and intrarater reliability between experts and nonexperts alike. Physicians' Global Assessment of Damage scores correlated with mouth asymmetry (P = .0021), cheek asymmetry (P = .04), and 3D-stereophotogrammetry ratings (median, mild: 27.5 vs moderate: 46.5 vs severe: 64, P = .0152). Lower face asymmetry correlated with worse quality-of-life scores (P = .013). LIMITATIONS: Small sample size and cross-sectional design. CONCLUSION: 3D stereophotogrammetry can reliably detect and quantify asymmetry in craniofacial morphea with greater sensitivity than that observed with traditional assessment alone. 3D stereophotogrammetry may be a useful adjunct to clinical examination.

Linear alopecia in pediatrics: RCM and dermoscopy reveal diagnostic cues.

BACKGROUND: Alopecia areata (AA), trichotillomania (TM), nevus sebaceous (NS), and linear scleroderma en coup de sabre (LSCS) can all present with a patch of linear alopecia, making diagnosis challenging. The purpose of this study was to combine reflectance confocal microscopy (RCM) and dermoscopy in the diagnosis of these lesions in children. METHODS: A total of 36 patients with linear alopecia were enrolled, of whom 14 had AA, seven had TM, nine had NS, and six had LSCS. We evaluated the characteristics and distinguishing features of the four conditions using RCM and dermoscopy. RESULTS: The key to differential diagnosis was the dermal Hair follicle density in the dermis was decreased in AA, and the size and density of the follicular openings were normal in TM. In NS, the major features were petal-like and frogspawn-like structures. In LSCS, dermal papillary rings, sebaceous glands, and follicles were partially or completely missing, and abundant fibrous material was distributed in the dermis. Dermoscopy revealed alopecia, and all four conditions resulted in decreased hair density. AA patients exhibited yellow dots, black dots, and exclamation mark hairs. TM patients presented with irregularly broken hairs and blood spots. Both NS and LSCS patients exhibited an absence of follicular openings; NS patients demonstrated whitish and yellowish round structures, while an atrophic area with white patches, linear vessels, and no yellow or black dots was observed in LSCS patients CONCLUSION: RCM combined with dermoscopy can provide additional information on disease states and differentiate between AA, TM, NS, and LSCS.

Bilateral en coup de sabre morphea in a male child: A rare presentation.

En coup de sabre is a rare subtype of morphea. Only a few bilateral cases have been reported to date. We report a case of a 12-year-old male child with two linear brownish depressed asymptomatic lesions over the forehead with hair loss on the scalp. After thorough clinical, ultrasonography and brain imaging, a diagnosis of bilateral en coup de sabre morphea was made and the patient was treated with oral steroids and weekly methotrexate.

Disturbances of the stomatognathic system and possibilities of its correction in patients with craniofacial morphea.

Morphea en coup de sabre and progressive hemifacial atrophy are extremely rare connective tissue disorders causing facial deformity. In extreme cases, morphological disorders are accompanied by symptoms of a clear impairment of the stomatognathic system. The aetiology of the above-mentioned diseases is still unknown. Properly planned therapy in the field of maxillofacial orthopaedics makes it possible to correct the asymmetric pattern of hard tissue growth and thus enable rehabilitation. The task of augmentation techniques is the volumetric supplementation of tissue defects resulting from atrophic processes. The degree of destruction and the extent of changes determine the method of correction. Mild and moderate defects are treated mainly with biomaterials and autologous adipose tissue. The severe course of hemifacial atrophy and morphea en coup de sabre and the associated significant tissue atrophy necessitate the search for more complex methods of treatment. In this paper, we summarize the disturbances of the stomatognathic system in patients with craniofacial morphea, together with an analysis of current treatment options.

Morphea mimicking facial capillary malformations: Two new cases and review of the literature.

Morphea and facial capillary malformations (port-wine stains) are distinct conditions that can affect the pediatric population. Early localized morphea mimicking a capillary malformation is an uncommon clinical presentation. We present two new cases of girls, aged 2 and 3 years, who presented with erythematous patches, initially diagnosed as capillary malformations, which were later diagnosed as morphea. We also performed a literature review, yielding 12 additional cases that underscore that the unusual presentation of morphea may delay correct diagnosis. Although early management of morphea reduces long-term sequelae, it is important to delay laser treatment for selected acquired vascular malformations, until the diagnosis of morphea is excluded.

Frontal Linear Scleroderma (en coup de sabre): A Case Report.

En coup de sabre is an unusual variant of localized scleroderma characterized by its distinct location involving the frontoparietal region of the forehead and scalp. The authors describe a rare case of en coup de sabre in a 3-year-old boy whose disease onset was at 12 months of age. This article presents the clinical manifestations of continuous changes in the lesion photographed over time. The clinical presentation, laboratory results, and radiological findings together with a brief discussion of the management of the disease are discussed.

Epilepsy in Parry-Romberg syndrome and linear scleroderma en coup de sabre: Case series and systematic review including 140 patients.

Parry-Romberg syndrome (PRS) and linear sclerosis en coup de sabre (LScs) are rare, related, autoimmune conditions of focal atrophy and sclerosis of head and face which are associated with the development of focal epilepsy. The scarcity of PRS and LScs cases has made an evidence-based approach to optimal treatment of seizures difficult. Here we present a large systematic review of the literature evaluating 137 cases of PRS or LScs, as well as three new cases with epilepsy that span the spectrum of severity, treatments, and outcomes in these syndromes. Analysis showed that intracranial abnormalities and epileptic foci localized ipsilateral to the external (skin, eye, mouth) manifestations by imaging or EEG in 92% and 80% of cases, respectively. Epilepsy developed before external abnormalities in 19% of cases and after external disease onset in 66% of cases, with decreasing risk the further from the start of external symptoms. We found that over half of individuals affected may achieve seizure freedom with anti-seizure medications (ASMs) alone or in combination with immunomodulatory therapy (IMT), while a smaller number of individuals benefitted from epilepsy surgery. Although analysis of case reports has the risk of bias or omission, this is currently the best source of clinical information on epilepsy in PRS/LScs-spectrum disease. The paucity of higher quality information requires improved case identification and tracking. Toward this effort, all data have been deposited in a Synapse.org database for case collection with the potential for international collaboration.

Treatment of morphea with hydroxychloroquine: A retrospective review of 84 patients at Mayo Clinic, 1996-2013.

BACKGROUND: Few studies support treating morphea (localized scleroderma) with hydroxychloroquine. OBJECTIVE: To assess the efficacy of hydroxychloroquine treatment of morphea. METHODS: We conducted a retrospective study of 84 patients who had morphea and were treated with hydroxychloroquine monotherapy for at least 6 months at our institution from 1996 through 2013. The median times to initial and maximal responses were assessed. RESULTS: Of the 84 patients (median age at diagnosis, 29.5 years), 65 (77.4%) were female, 36 (42.9%) had a complete response to hydroxychloroquine, 32 (38.1%) had a partial response greater than 50%, 10 (11.9%) had a partial response less than or equal to 50%, and 6 (7.1%) had no response. The median time to initial response was 4 months, and the median time to maximal response was 12 months. Ten patients (11.9%) experienced adverse effects from hydroxychloroquine; the most common adverse effect was nausea (6 patients). LIMITATIONS: Retrospective study. CONCLUSIONS: Hydroxychloroquine is a valuable treatment for morphea because of its high response rate and low rate of adverse effects; however, prospective studies are needed to determine its true efficacy.

Linear morphea: Clinical characteristics, disease course, and treatment of the Morphea in Adults and Children cohort.

BACKGROUND: Prospective, longitudinal studies examining the features of linear morphea are limited. OBJECTIVE: To utilize the Morphea in Adults and Children cohort to determine clinical characteristics, impact on life quality, and disease course of linear morphea in a prospective, longitudinal manner. METHODS: Characteristics of linear morphea versus other subtypes were compared in a cross-sectional manner. Next, linear morphea participants were examined in depth over a 3-year period. RESULTS: Linear morphea was the most common morphea subtype (50.1%, 291/581) in the cohort. Deep involvement was more common in linear (64.3%, 187/291) than other morphea subtypes. Linear morphea participants with deep involvement were more likely to have a limitation in range of motion (28.6%, 55/192) than those without (11.1%, 11/99, P < .001). Adult-onset disease occurred in 32.6% (95/291) of those with linear morphea. Frequency of deep involvement was similar between pediatric (66.8%, 131/196) and adult-onset linear morphea (58.9%, 56/95, P = .19). Quality of life and disease activity scores improved over time, while damage stabilized with treatment. LIMITATIONS: Results of the study are associative, and the University of Texas Southwestern Medical Center is a tertiary referral center. CONCLUSION: A substantial number of linear morphea patients have adult-onset disease. In all age groups, linear morphea with deep involvement was associated with functional limitations.

Natural history and extracutaneous involvement of congenital morphea: Multicenter retrospective cohort study and literature review.

BACKGROUND: Congenital morphea is a form of localized scleroderma that presents at birth. There is limited information on its presentation and progression. METHODS: Patients with congenital morphea were identified from five pediatric dermatology and rheumatology tertiary care centers in Canada, the United States, and Italy from 2001 to 2016. Cases from the literature were identified by searching Ovid (EMBASE and MEDLINE) from inception to June 30, 2017. Disease characteristics and prevalence of extracutaneous involvement were analyzed. RESULTS: Thirteen patients were identified from the five centers, and 13 cases were described in the literature, representing 25 patients, with one duplication. Fourteen patients (56%) were female. Median age at diagnosis was 2.9 years (interquartile range 1.2-5.1 years). Linear morphea, including en coup de sabre and Parry-Romberg syndrome, was the most common subtype observed (n = 19, 76%), followed by circumscribed (n = 5, 20%), generalized (n = 2, 8%), and mixed (n = 2, 8%). The face (n = 14, 56%), scalp (n = 8, 32%), and trunk (n = 6, 24%) were the most common locations affected. Most lesions were active at diagnosis (n = 19, 76%), but all patients with follow-up later became inactive. Extracutaneous involvement was seen in 12 (48%) patients, all of whom had linear morphea. Musculoskeletal sequelae were seen in those with linear morphea of the extremities (4/5, 80%), and neurologic involvement was seen in those with linear morphea of the head (8/13, 62%). CONCLUSION: Congenital morphea is associated with extracutaneous manifestations and delayed diagnosis. More research is needed to determine whether early recognition, monitoring, and treatment can alter the disease course.

Neurological abnormalities in localized scleroderma of the face and head: a case series study for evaluation of imaging findings and clinical course.

INTRODUCTION: Localized scleroderma (LoS) of the face and head is often associated with neurological manifestations and/or imaging abnormalities in the central nervous system (CNS). CASE SERIES: We present an analysis of 20 cases of LoS affecting the face and head. The CNS symptoms and/or abnormalities in high-resolution computed tomography (HRCT) and/or magnetic resonance imaging (MRI) were observed in 12 patients (60%). In addition to the mild and unspecific disorders (e.g. headaches), serious neurological complications probably in the course of vasculitis were revealed: epilepsy (in two patients), epilepsy and pyramidal sings (in one patient). Neurological disorders and LoS occurred at the same time (in three patients) or at the course of the disease (nine patients) and no later than 29 years since the onset of the disease. No link between neurological disorders and the LoS clinical morphology, immunological and other laboratory parameters has been established. CONCLUSIONS: CNS involvement is not correlated with the clinical course of the facial and head LoS and may occur years after the disease initial symptomatology. Imaging follow-up is not required if there is not any emerging neurological symptom. In some cases, however, both HRCT and MRI are useful for monitoring disease evolution and addressing therapeutic choices.

Treatment of Linear Scleroderma (en Coup de Sabre) With Dermal Fat Grafting.

BACKGROUND: Linear scleroderma, also known as "en coup de sabre," is a subtype of localized scleroderma that warrants aesthetic correction because it appears on the forehead region in children. OBJECTIVE: To report dermal fat grafting as a novel and effective surgical treatment option in linear scleroderma. METHODS: Under local anesthesia, a dermal fat graft was successfully placed into a subcutaneous pocket that was prepared underneath the depressed scar. The donor site was closed primarily. RESULTS: No early or late complications developed postoperatively. After 1-year follow-up, the dermal fat graft was viable, the depressed scar was adequately augmented, and a good aesthetic result and patient satisfaction were obtained. CONCLUSION: We believe that dermal fat grafting is a cost-effective option and provides a long-lasting aesthetic outcome in the management of linear scleroderma.

Challenges and complications in juvenile localized scleroderma: A practical approach.

Juvenile localized scleroderma is characterised by inflammation which drives fibrosis in skin and soft tissues. The more severe subtypes of localized scleroderma such as linear and craniofacial are more common in children. Additionally, extracutaneous involvement is seen in half of all children and is associated with poorer treatment outcomes and health-related quality of life. Evidence for the management of craniofacial and extracutaneous involvement is lacking and therefore poses a challenge to clinicians. This review aims to provide a practical approach to management of these most challenging features of juvenile localized scleroderma through case studies where we present the available evidence, current recommendations and considerations for management.

Seizure in Morphea: A Case Report of Parry-Romberg Syndrome.

Parry-Romberg syndrome is a rare neurocutaneous disease characterized by progressive hemifacial atrophy. We present the case of a 14-year-old, a known case of linear morphea, who presented with seizure and on evaluation was diagnosed with Parry-Romberg syndrome. It causes a profound impact on aesthetic well-being and has a significant psychosocial morbidity. This case report aims to highlight the effective multidisciplinary team approach involving a rheumatologist, dermatologist, neurologist, and ophthalmologist which ultimately culminated in the meticulous management of the disease in our patient.

Damage evaluation of craniofacial localized scleroderma using magnetic resonance imaging.

Background: Localized scleroderma (LoS) is an autoimmune disease in which craniofacial lesions can cause severe facial deformities with brain involvement. Objective evaluation of craniofacial LoS is challenging. Magnetic resonance imaging (MRI) may be used as a damage assessment tool. This study aimed to analyze the tissue involvement of craniofacial LoS based on MRI and evaluate MRI for craniofacial LoS assessment. Methods: This cross-sectional study included patients with craniofacial LoS from September 2021 to August 2022 in Peking Union Medical College Hospital. Patients who were clinically assessed in a stable phase were enrolled; patients with previous surgical treatment or contraindications to MRI were excluded. Participants underwent clinical, MRI, and ultrasound assessments. MRI was compared with ultrasound by correlation analysis and Bland-Altman analysis. The involvement of different tissues and different facial subunits was compared. The accumulated soft tissue atrophy index (ASTAI) was compared with clinical scores by correlation analysis. Results: A total of 28 patients were included (13 female; mean age, 18 years). MRI showed a good correlation and agreement with ultrasound (r=0.916, P<0.001). In different facial subunits, a significant negative correlation between the forehead and chin was found (r=-0.593, P=0.001). The ASTAI correlated well with the facial LoS damage index (r=0.580, P=0.001) and the Peking Union Medical College LoS facial aesthetic index (PUMC LoSFAI) (r=0.921, P<0.001). A total of 38.6% of clinical scores were inaccurate based on MRI. Neurological changes were found in one patient. Conclusions: MRI can reliably quantify damage in craniofacial LoS, and may serve as a useful and objective tool for overall craniofacial LoS evaluation.

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.

En coup de sabre morphea: an uncommon condition in Africa.

The term en coup de sabre morphea refers to a lesion of linear morphea typically located in the frontoparietal scalp and/or the paramedian forehead, often resembling a strike with a sword. In literature, en coup de sabre morphea, and en coup de sabre scleroderma are terms used interchangeably and synonymously. Due to the rarity of this condition, treatment is largely based on case report series, leaving much room for speculation in terms of drugs of choice, duration of treatment, and dosages. Although it typically leaves behind notable and often permanent skin pigmentary changes and indentation of the affected areas, this condition usually remits spontaneously, even in the absence of an active form of treatment. The disease severity and prognosis vary according to the subtype: circumscribed morphea has a generally more benign course when compared with linear scleroderma and generalized morphea.

Clinical and therapeutic course in head variants of linear morphea in adults: a retrospective review.

Parry Romberg Syndrome (PRS) and en coup de sabre (ECDS) are head variants of linear morphea with functional and structural implications. This study describes the clinical course, autoimmune co-morbidities, complications, and treatment of adults with PRS/ECDS at a tertiary referral center. We retrospectively reviewed the records of all 34 adult patients with PRS/ECDS identified through billing code search and seen by dermatologists at our institution between 2015 and 2021. Eight patients (23.5%) had ECDS, 8 (23.5%) had PRS, and 18 (52.9%) had overlap. Twenty-six patients (76.5%) reported ocular, oral, and/or neurologic symptoms, and 8 (23.5%) had concomitant autoimmune/inflammatory conditions. Sixteen patients (47.1%) had a skin biopsy, and 25 (73.5%) had imaging. Forty-six MRIs were obtained, of which 6 (13.0%) reported intracranial findings and 25 (54.3%) reported disease-related connective tissue damage. Twenty-four patients (70.6%) underwent systemic treatment during their disease course per available clinical records. Seventeen patients (70.8%) had improved or stable disease upon treatment completion, with an average duration of 22.2 months. Ten patients (41.7%) reported recurrence of disease following the treatment course. To address changes to facial contour, 6 patients (17.6%) opted for procedural treatments. One patient (16.7%) experienced morphea reactivation following a filler injection performed off-immunosuppression. Compared to findings in children, our study suggests adults with PRS/ECDS are more likely to have oral and ocular complications but experience less severe neurologic symptoms. While systemic treatments appear beneficial in most adult patients with PRS/ECDS, disease may recur following discontinuation.
