Remission of seizures with immunosuppressive therapy in Parry-Romberg syndrome and en coup de sabre linear scleroderma: Case report and brief review of the literature

Alloplastic implants for skeletal augmentation in Parry-Romberg syndrome: A systematic review

Parry-Romberg syndrome (PRS) is a rare disorder characterized by progressive hemifacial atrophy affecting soft tissue and, in severe cases, bone. Reconstructive surgery is commonly used to manage PRS-related facial deformities. This systematic review assesses the current literature on alloplastic implants for facial reconstruction in PRS. Following PRISMA guidelines, we conducted a systematic review across MEDLINE, Google Scholar, and Cochrane databases, including English-language studies on PRS managed with alloplastic implants. Eleven studies, including 74 PRS patients (age range 12-45, mean 22.3), were analyzed. Most patients received off-the-shelf implants, with a single case using a 3D-modeled titanium implant. Implants, often adjunctive to free flap-based soft tissue augmentation, fat grafting, or orthognathic surgery, were typically placed in the malar, mandibular, or mental regions, with porous polyethylene (Medpor) being the most frequently used material. Complications were minimal, with infections (n = 2) and one aesthetic issue requiring removal (follow-up range: six months to 13 years; mean 39 months). Alloplastic implants effectively restore facial symmetry in PRS, commonly alongside soft tissue reconstruction. Future studies on custom-designed implants are warranted to enhance treatment consistency and long-term outcomes.

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.

Therapeutic and Reconstructive Management Options in Scleroderma (Morphea) en Coup de Sabre in Children and Adults. A Systematic Literature Review

Scleroderma (morphea) en coup de sabre is a localized subtype restricted to the frontoparietal region of the head. Current treatment paradigms rely on low levels of evidence, primarily case reports and case series-supported by expert opinions. The aim of this article was to systematically analyze current data related to the treatment of localized scleroderma en coup de sabre. The databases Scopus, PubMed, and EBSCO were searched for all reports discussing the treatment of localized scleroderma en coup de sabre. The keywords en coup de sabre, “facial linear scleroderma”, and “morphea linearis”, combined with “treatment” or “therapy” were used as search terms. A total of 34 articles analyzed treatment outcomes for patients with localized scleroderma en coup de sabre including 4 retrospective cohort studies, 2 prospective cohort studies, 4 case series, and 24 case reports, representing a total of 69 patients (38 children and 31 adults). Methotrexate was the most commonly investigated treatment (26 patients) with a highest response rate (26/26, 100%). Other treatments included systemic glucocorticosteroids (nine patients), followed by UVA1 (four patients), mycophenolate mofetil (two patients), hydroxychloroquine (five patients), abatacept (two patients), tocilizumab (three patients), cyclosporine (one patient), interferon gamma (one patient), PUVA therapy (two patients), NB-UVB therapy (one patient), and pulsed dye laser (one patient). Reconstructive and surgery treatment was successfully used for lesions with settled disease activity to improve the cosmetic aspect of the lesions. Conclusion: methotrexate is the most often-studied treatment and reported good clinical outcomes in children and adults with localized scleroderma en coup de sabre.

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.

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.

Parry Romberg disease with En Coup de Sabre Scleroderma: Effect of tocilizumab on periodontal bone inflammation

Parry Romberg disease and En Coupe de Sabre Scleroderma are frequently associated disorders that affect the face and can cause severe aesthetic and functional impairment. Systemic immunosuppression is the gold standard of first-line treatment in the pediatric rheumatology standpoint although it is often delayed in the pediatric dermatology clinics and more often used in cases of refractory neurological impairment. We report on a case with dental root resorption and severe periodontal bone inflammation detected on magnetic resonance imaging, which was successfully treated with the anti-IL-6 agent tocilizumab.

Unilateral Neuroimaging Findings in Pediatric Craniofacial Scleroderma: Parry-Romberg Syndrome and En Coup de Sabre

OBJECTIVE

Parry-Romberg syndrome (PRS) and en coup de sabre (ECDS) are subtypes of craniofacial localized scleroderma. Systematic analyses of central nervous system imaging findings and their clinical associations in children are lacking. Here, we aim to characterize neuroimaging findings and associated neurological symptoms in these conditions.

METHODS

Neuroimaging and neurological symptoms of children evaluated at our institution with a diagnosis of PRS or ECDS were retrospectively reviewed. Laterality, location, stability, and number of lesion(s) were evaluated, as was the presence of susceptibility lesion(s) and contrast enhancement. History of seizures or headaches was noted.

RESULTS

From 2003 to 2019, 80 patients with PRS or ECDS were followed at our institution. Neuroimaging was completed in 73 and found to be abnormal in 25. In 12 (48%) of these 25 cases, headaches and/or seizures were present. In the vast majority of these cases (22/25, 88%), lesions were ipsilateral to skin findings. White matter was involved in 19 (76%) patients. MRI abnormalities preceded a rheumatological diagnosis in 7 (28%). Susceptibility lesions were noted in 11 (44%), and 8 (73%) of these patients endorsed a history of headaches. Most lesions were in the supratentorial compartment, did not enhance, and were stable at 1-year follow up imaging. Of those with progression, susceptibility findings were present at baseline.

CONCLUSIONS

Neuroimaging findings in pediatric PRS and ECDS are often supratentorial, stable, unilateral, and ipsilateral to skin findings, and they can precede cutaneous findings.

A Case Report of Parry-Romberg Syndrome Misdiagnosed as Multiple Sclerosis

Background: Parry–Romberg syndrome (PRS) is a rare disease that causes hemiatrophy of the face. The pathophysiological mechanisms involved in its etiology are unknown, but several previous reports suggest the involvement of autoimmune factors. Herein we describe the case of a patient with PRS who was initially misdiagnosed as having multiple sclerosis (MS). The relevant literature is briefly reviewed, and some previous reports suggesting associations between PRS and autoimmunity are discussed.

Case Presentation: A 34-year-old man presented with recurrent paroxysmal weakness of the right hand, a 3-years history of unilateral tinnitus, and headache for 6 months. MS was initially diagnosed but the patient was subsequently diagnosed as having PRS on the basis of clinical manifestations and radiological findings.

Conclusions: PRS may be associated with autoimmune pathogenesis, but the present case does not support that theory.

Treatment in Juvenile Scleroderma

PURPOSE OF REVIEW

Treatment of scleroderma in children is challenging since little is known about its pathogenesis. Herein, we review the most recent evidence regarding the treatment of juvenile scleroderma.

RECENT FINDINGS

According to the recent recommendations for Pediatric Rheumatology in Europe (SHARE), systemic treatment in localized scleroderma is needed when there is a risk for disability, such as in generalized or pansclerotic morphea and progressive linear scleroderma. In juvenile systemic sclerosis, the introduction of the severity score, J4S, has standardized the assessment of the patients in the daily practice and allowed a more tailored therapeutic approach. Since, to date, no clinical trial is available in JSSc, due to its rarity, the treatment is based on adults' experience. The recent recommendations for juvenile scleroderma represent an important instrument to standardize the treatment approach, confirm the role of methotrexate, and open new windows for effective experimental treatments, such as mycophenolate mofetil and biological agents, for severe or refractory cases.

Linear Scleroderma of the Head - Updates in management of Parry Romberg Syndrome and En coup de sabre: A rapid scoping review across subspecialties

To provide an update on the current management, including evaluation and treatment, and the available diagnostic tools for linear scleroderma of the head, i.e., Parry-Romberg Syndrome and en coup de sabre (PRS/ECDS). A rapid scoping review of the literature was conducted to include manuscripts published in English between 2010 and 2019. Literature searches were performed in PubMed and EMBASE databases. The were analyzed for descriptive statistic reporting. This study reviewed 215 manuscripts reporting these 1430 patients. Surgical reports comprised the majority of the reviewed literature. Most PRS/ECDS did not appear to receive comprehensive multisubspecialty evaluation for extracutaneous manifestations; 21% of cases noted neurological screening, 4% noted dental screening, and 3% noted ophthalmologic screening. Methotrexate and glucocorticoids remain the most frequent choice for immunosuppressive treatment, though fewer than 7% of patients reported receiving systemic medical therapies. Surgical procedures for cosmetic or functional improvement were common (59%) among the reported patients. Autologous fat grafting was the most frequently utilized cosmetic treatment (50% of procedures) followed by free flap transfers (24% of procedures). There is ongoing need for standardized evaluation, monitoring, and treatment to prevent morbidity in PRS/ECDS, especially in children. When these patients are managed by rheumatologists, methotrexate, and steroids remain the first-line treatment, but a review of the published literature reflects that this may be a minority. Most PRS/ECDS patients are not evaluated in a multidisciplinary fashion. We propose comprehensive evaluations across subspecialties at the baseline and follow-up levels to monitor disease activity and record extracutaneous manifestations, treatment algorithms, and surgical intervention considerations.

Epilepsy in paediatric patients with Parry-Romberg syndrome: A review of the literature

BACKGROUND

Parry-Romberg syndrome (PRS) is a rare disorder characterized by unilateral slow progressive facial atrophy that can be associated with neurologic manifestations, namely seizures. There is scarce data about seizures in paediatric patients with PRS. The aim of our work was to clarify the clinical features of paediatric patients with PRS and seizures.

METHODS

We performed a literature review based on a literature search using PubMed and EMBASE databases. We included original articles in which the main diagnosis was PRS and the patients were 17 years old or less when the first seizure occurred.

RESULTS

We included 40 patients. Most of the patients had previously normal development and had their first seizure in the first decade of life. Neurologic examination was abnormal in 56 % of patients. Seizures are typically focal, frequently with impaired awareness, and became refractory in about 40 % of patients. Few patients have generalized seizures. On electroencephalogram, epileptic discharges are generally focal, on the same side as the facial atrophy, without a predominant cerebral lobe localization. Brain MRI is almost always abnormal, typically with T2 subcortical hyperintensities, and sometimes brain atrophy or calcifications. In addition to the classic antiepileptic drugs, immunosuppressive drugs should be considered as potential epilepsy treatment.

CONCLUSION

To the best of our knowledge, this is the first review dedicated to the characteristics of paediatric patients with PRS and epilepsy. Seizures are usually focal, became refractory in 40 %, and have a significant impact on the quality of life and neurodevelopment of patients.

Update on the Systemic Treatment of Pediatric Localized Scleroderma

Juvenile localized scleroderma (jLS) is an orphan disease that can lead to cosmetic disfiguration and orthopedic problems. Two recent publications review the current recommendations regarding diagnosis, assessment, follow up and treatment of pediatric localized scleroderma cases, both of which suggest the Localized Scleroderma Cutaneous Assessment Tool as an important instrument to assess activity and damage. This review focuses on the systemic treatment of jLS. Systemic treatment includes synthetic and biologic disease-modifying antirheumatic drugs. Systemic therapy is indicated if the lesion crosses any joint, or leads to potential cosmetic disfiguration or orthopedic problems. The only controlled trial of systemic treatment has shown the efficacy of methotrexate, which is the first choice of treatment. It appears superior to phototherapy according to a recently published meta-analysis. In case of methotrexate intolerance, mycophenolate mofetil is an option. In case of methotrexate nonresponse, addition of mycophenolate mofetil, tocilizumab or abatacept seems to be effective. Future treatment options derived and extrapolated from adult trials regarding treatment of skin involvement of systemic scleroderma or fibrosis are promising, as the final pathway in the skin seems to be similar in both diseases.

Parry-Romberg syndrome associated with en coup de sabre in a patient from South Sudan - a rare entity from East Africa: a case report

Background

Parry–Romberg syndrome, also known as progressive hemifacial atrophy, is a rare degenerative disorder with numerous distinctive clinical presentations. It is usually slowly progressive, occurring more in females, and affects primarily one side of the face; it causes unilateral atrophy and loss of skin, subcutaneous tissue, muscles, and bones, and can even extend to oral structures. Other involvements that can occur are ocular and neurological; however, it is frequently associated with linear scleroderma, known as en coup de sabre. The etiology of the disorder is unknown, although some consider it a variant of morphea (localized scleroderma) and others proposed a malfunction of the sympathetic system as a cause. Imaging studies can support diagnosis and reveal the extent of the disease. Moreover, with the wide systemic involvement in such a condition, a multidisciplinary approach is crucial.

Case presentation

A 35-year-old Dinka woman presented with left hemifacial atrophy associated with left-sided body hemihypoesthesia and glaucoma with overlapping linear scleroderma “en coup de sabre” for 5 years.

Conclusions

Parry–Romberg syndrome is a very rare entity causing progressive hemifacial atrophy that could also be associated with linear scleroderma. It has devastating outcomes due to its various systemic involvements; therefore, a multidisciplinary approach is required together with further studies to be performed in order to identify the key etiology and construct a clear guideline for management.
