Adult linear scleroderma en coup de sabre with epileptic seizure and Coats-like response: a case report and literature review / 中华神经科杂志

Objective:To report the clinical characteristics, diagnosis and treatment of a patient with linear scleroderma en coup de sabre (LSCS), and review the relevant literature in order to provide the basis for early diagnosis and timely treatment of the disease.Methods:The clinical data and treatment process of a patient with LSCS admitted to Hangzhou Traditional Chinese Medicine Hospital Affiliated to Zhejiang Chinese Medical University on September 22, 2022 were summarized, and the case reports or case series studies related to LSCS with epilepsy or Coats-like response at home and abroad were systematically analyzed. The gender, age, onset time, clinical manifestations, treatment and prognosis of this type of patients were summarized.Results:The patient is a 22 years old female with a history of scalp patchy alopecia and ipsilofrontal en coup de sabre for over 10 years and was diagnosed as Coasts disease due to decreased vision in the right eye 5 years ago, and now she is blind. This visit was due to "episodic loss of consciousness for more than 2 hours" with epileptic seizures and Coats-like response of the left eye. Treatment with antiepileptic drugs, glucocorticoids and immunosuppressants showed satisfactory results. The clinical data of all 20 patients with LSCS reported in domestic and foreign literature were analyzed. The age of onset was 11.00 (6.75, 20.50) years, with a male to female ratio of 1∶1. The imaging findings of patients with LSCS with epilepsy were mainly manifested as multiple brain calcifications, soft tissue atrophy and skull thinning on the focal side. The results of fundus examination and fundus fluorescein angiography in patients with LSCS with Coats-like response were mainly exudative inflammation and retinal detachment, including 1 case with cerebral cerebrovascular inflammation. In terms of treatment, most of the patients with LSCS with epilepsy were treated with antiepileptic drugs, glucocorticoids combined with immunosuppressant, interleukin-6 inhibitor tozizumab, and the other 2 cases were treated with surgery. Patients with LSCS with Coats-like response were treated with intravitreal bevacizumab in combination with glucocorticoids and immunosuppressive therapy or retinal targeted photocoagulation or local laser therapy with triamcinolone. The above treatment can control the patient′s refractory epilepsy and improve the vision loss.Conclusions:The main manifestations of LSCS are en coup de sabre lesion with pigmentation on the forehead above the eyelid, accompanied by Coats-like response of the eye, epilepsy, and brain imaging abnormalities. The above clinical features may appear successively or simultaneously. In some patients, these symptoms may progress slowly, and can lead to blindness and refractory epilepsy severely. Glucocorticoids combined with immunosuppressive therapy should be given as early as possible, and intravitreal bevacizumab therapy can improve visual loss of LSCS patients.

Morfea en edad pediátrica / Morphea in childhood

La morfea es una rara enfermedad fibrosante de piel y tejidos subyacentes que aparece a cualquier edad, con más frecuencia en mujeres. Es de etiología autoinmune, benigna, con remisión espontánea o recidivante crónica; y se caracteriza por la aparición de áreas de piel esclerosadas, únicas o múltiples, redondeadas o lineales, asintomáticas, de evolución crónica y sin afección sistémica. Se presentó un paciente en edad pediátrica con esta enfermedad, cuya clínica, examen diagnóstico e histología fueron compatibles con la enfermedad de morfea lineal que, a pesar del retraso en su diagnóstico una vez iniciado el tratamiento inmunosupresor presentó una evolución favorable, simultáneamente se le realizó fisioterapia.

Morphea is a rare fibrosing disease of the skin and underlying tissues which is more common in women and can appear at any age. It is an autoimmune and benign disease with spontaneous remission or chronic relapsing course; it is characterized by the appearance of single or multiple, rounded or linear, asymptomatic, chronically evolving sclerosed skin areas without systemic involvement. We present a female pediatric patient with this disease, whose symptoms, diagnostic examination and histology were compatible with linear morphea that, despite the delay in its diagnosis, she had a favorable evolution once immunosuppressive treatment was started, and physiotherapy was simultaneously performed.

Efficacy of autologous fat grafting in the treatment of 40 cases of stable linear scleroderma: a retrospective analysis / 中华皮肤科杂志

Objective:To investigate the efficacy of autologous fat grafting in the treatment of stable linear scleroderma.Methods:A retrospective analysis was performed on 40 patients with stable linear scleroderma who received autologous fat grafting from October 2017 to November 2020 in the Department of Dermatology, Xijing Hospital, Air Force Medical University. There were 22 males and 18 females, aged 12 - 36 (18.2 ± 4.82) years. Skin lesions involved the forehead in 16 cases, the perioral area in 4, the lower jaw in 2, the cheek in 9, the trunk in 5, and the lower limb in 4, and the size of depressed skin defects was 3 - 24 cm 3. The patients′ subjective satisfaction rate, the decrease in the size of depressed skin defects, and the incidence of adverse reactions after autologous fat grafting were analyzed during the follow-up. Results:Six months after the grafting, 40 patients were followed up and evaluated, and the size of depressed skin defects markedly decreased. The satisfaction rate for appearance improvement after the first grafting was 60% (24/40) ; 35 patients received the second grafting, with a satisfaction rate of 88.6% (31/35) ; 17 received the third grafting, with a satisfaction rate of 94.1% (16/17) ; the total satisfaction rate was 87.5% (35/40). After the grafting, local skin unevenness was observed in the grafting area in 3 patients, and in the liposuction area in 2. The incidence rate of postoperative adverse reactions was 12.5% (5/40) .Conclusion:Autologous fat grafting was markedly effective in the treatment of stable linear scleroderma.

Construction and validation of a prediction model for staging of localized scleroderma lesions based on high-frequency ultrasound / 中华皮肤科杂志

Objective:To analyze clinical characteristics and high-frequency ultrasound features of localized scleroderma, and to construct and validate a non-invasive prediction model for staging of skin lesions based on the high-frequency ultrasound features.Methods:Patients with localized scleroderma were retrospectively collected from the Department of Dermatology and Venereology, Second Xiangya Hospital of Central South University from February 1, 2021 to February 28, 2023, and clinical data as well as high-frequency ultrasound and pathologic features of 85 lesions from these patients were analyzed. Lesions were divided into modeling cohort and validation cohort according to the chronological order of patient enrollment. The univariate analysis and multivariable logistic regression models were used to analyze the independent influential factors in the staging of localized scleroderma lesions in the modeling cohort, construct the regression equation, and to build a nomogram prediction model. The Bootstrap validation method was used for internal validation, and the predictive performance of the nomogram model in the modeling cohort and validation cohort was further evaluated by the calibration curve and receiver operating characteristic (ROC) curve.Results:In the modeling cohort, 60 patients with localized scleroderma, including 16 males and 44 females, were enrolled, with the age [ M ( Q1, Q3) ] being 22.0 (10.0, 39.2) years, and there were 28 lesions in the oedematous phase and 32 lesions in the fibrotic and atrophic phase; in the validation cohort, 25 patients with localized scleroderma, including 8 males and 17 females, were enrolled, with the age being 18.0 (7.0, 30.0) years, and there were 9 lesions in the oedematous phase and 16 lesions in the fibrotic and atrophic phase. Univariate analysis in the modeling cohort showed no significant differences in the age and gender of patients or the location of lesions between the oedematous phase group and the fibrotic and atrophic phase group (all P > 0.05) ; compared with the oedematous phase group, the fibrotic and atrophic phase group showed an increased proportion of patients with disease duration ≥ 2 years (20/32 cases vs. 10/28 cases, χ2 = 4.29, P = 0.038), decreased thicknesses of the subcutaneous fat layer in skin lesions (1.4 [0.0, 26.0] mm vs. 1.8 [0.1, 14.3] mm, Z = -2.14, P = 0.032), increased decrements in the subcutaneous fat layer thickness in the lesional sites compared with non-lesional control sites (1.8 [0.5, 11.0] vs. 0.3 [-1.9, 8.0] mm, Z = -4.72, P < 0.001), increased ratios of the lesional elasticity values to control elasticity values (2.9 [1.8, 6.9] vs. 1.8 [1.1, 5.9], Z = -4.34, P < 0.001), and increased ultrasound-based lesional activity scores (5.0 [3.0, 8.0] points vs. 3.0 [0.0, 5.0] points, Z = -4.76, P < 0.001). Multivariable logistic stepwise regression analysis showed that the disease duration ≥ 2 years ( P = 0.032), increased ratios of the lesional elasticity values to control elasticity values ( P = 0.019), increased ultrasound-based lesional activity scores ( P = 0.013), and increased decrements in the subcutaneous fat layer thickness in the lesions compared with the controls ( P = 0.013) helped to confirm localized scleroderma lesions in the fibrotic and atrophic phase. Based on the results of regression analysis, a total of 4 factors were included in the nomogram prediction model, including the disease duration, the decrement in the subcutaneous fat layer thickness in lesions compared with controls, the ratio of the lesional elasticity values to control elasticity values, and the ultrasound-based lesional activity score; additionally, the constructed logistic regression model formula for predicting the probability (p) of skin lesions in fibrotic and atrophic phase was "ln (p/[1 - p]) = -9.595 + 2.204 × the disease duration + 0.784 × the decrement in the subcutaneous fat layer thickness in the lesions compared with the controls (mm) + 0.887 × the ratio of the lesional elasticity values to control elasticity values + 1.374 × the ultrasound-based lesional activity score". The calibration curve showed a good predictive performance of the model through the Bootstrap validation method, and the ROC curve demonstrated good discrimination and accuracy (modeling cohort: area under the curve = 0.936, 95% CI: 0.879 - 0.994; validation cohort: area under the curve = 0.889, 95% CI: 0.748 - 1.000) . Conclusions:High-frequency ultrasound could provide essential details for staging the localized scleroderma lesions. Based on the disease duration, subcutaneous fat layer thickness, skin elasticity values, and ultrasound-based lesional activity scores, the constructed prediction model could predict the stages of localized scleroderma lesions with excellent discrimination, accuracy, and predictive performance.

Conventional ultrasound combined with elastography for evaluating active lesions of juvenile localized scleroderma / 中国医学影像技术

Objective To observe the value of conventional ultrasound combined with ultrasonic elastography for evaluating the severity of active lesions of juvenile localized scleroderma(JLS).Methods Totally 27 JLS children with 46 active lesions were prospectively enrolled.The thickness,echo and blood flow of skin and subcutaneous tissue of JLS lesions and the paired sites were evaluated using conventional ultrasound,while the skin stiffness of all lesions and paired sites were assessed using shear wave elastography(SWE),and the strain ratio of lesions and surrounding skin were evaluated using strain elastography(SE).The thickness,echo and blood flow of skin as well as subcutaneous tissue,and the Young's modulus of skin were compared between JLS active lesions and the paired sites.The correlations of the individual sum total of each Young's modulus and the limited scleroderma activity index(LoSAI)or the limited scleroderma injury index(LoSDI)were explored.Results Compared with the paired site,no significant difference of the skin thickness was found among 46 JLS lesions(P＞0.05),but JLS lesions had thinner subcutaneous tissue(P＜0.05)and greater Young's moduli(all P＜0.05).The strain ratio of the lesions and surrounding skin were all larger than 2.For JLS children with active lesions,the individual sum total of Young's moduli had moderate rank correlations with LoSAI(rs=0.63-0.69,all P＜0.05),but there was no significant rank correlation with LoSDI(rs=0.27-0.33,P＞0.05).Conclusion Compared with the paired site,JLS active lesions had thinner subcutaneous tissue and stiffer skin.The higher the lesion skin stiffness,the more severe the JLS lesion activity.

Reconstrução de hemiatrofia facial com hidroxiapatita de cálcio: relato de uma técnica segura e minimamente invasiva / Reconstruction of facial hemiatrophy using calcium hydroxylapatite filler: report of a safe and minimally invasive technique

Introdução: a hemiatrofia facial progressiva, também conhecida como síndrome de Parry Romberg, é uma forma rara de esclerodermia, cujo manejo de sequelas é desafiador. Objetivo: diante desse desafio, o objetivo deste estudo foi avaliar pela primeira vez na literatura a eficácia do preenchimento da hidroxiapatita de cálcio (CaHa) na reconstrução da mandíbula de um paciente com síndrome de Parry Romberg. Relato do caso: paciente do sexo feminino, 15 anos, com atrofia progressiva do lado direito da face por síndrome de Parry Romberg. Após o controle da doença, a principal queixa da paciente era assimetria facial, principalmente na região mandibular. Discussão: a CaHa é um preenchedor injetável biocompatível, que é gradualmente reabsorvido e substituído por estroma fibrovascular, formado principalmente por novo colágeno, em um processo que ocorre sem qualquer reação imunológica. Este perfil de segurança torna a CaHa uma boa escolha para a correção de sequelas de esclerodermia estável. Conclusão: este relato permite concluir que a biocompatibilidade do preenchimento de CaHa e a adequação para correção da mandíbula também são aplicáveis em procedimentos reconstrutivos para esclerodermia estável, de forma segura e minimamente invasiva, com ótimos resultados estéticos. O procedimento deve ser programado caso a caso, e um acompanhamento regular também é recomendado.

Introduction: Progressive Facial Hemiatrophy, also known as Parry Romberg Syndrome, is a rare form of linear scleroderma. The management of facial atrophy sequelae is challenging. Objective: This study aims to evaluate for the first time in literature the effectiveness of the calcium hydroxylapatite (CaHa) filler in the jawline reshaping of a patient with Parry Romberg Syndrome. Case report: A 15-year-old woman with progressive atrophy of the right side of the face due to Parry Romberg Syndrome. After disease control, the patient's main complaint was facial asymmetry, mainly in the jawline region. Discussion: CaHa is a biocompatible injectable filler that is gradually resorbed and replaced by fibrovascular stroma, mainly formed for new collagen, in a process that occurs without any immunological reaction. This safety profile makes CaHa a good choice for correcting stable scleroderma defects. Conclusion: This report concludes that CaHa filler biocompatibility and suitability for the jawline correction are also applicable in reconstructive procedures for stable scleroderma, safely and minimally invasively, with optimal aesthetic results. The method must be programmed case-by-case, and a regular follow-up is also recommended.

Clinical features and classification of 180 patients with morphea / 中华皮肤科杂志

Objective:To determine classification and clinical features of morphea.Methods:A retrospective analysis was conducted on epidemiological information about clinical manifestations of and laboratory data from 180 patients with morphea, who visited Zhongshan Hospital, Fudan University from January 2010 to July 2021. Two-independent-sample t test was used to compare the age at onset between genders, and chi-square test to analyze differences in clinical characteristics between different genders and subtypes. Results:Among the 180 patients, 123 were females and 57 were males, with a male-to-female ratio of 1∶2.16. The age at onset of morphea was 28.69 ± 17.97 years for female patients, and 29.90 ± 20.67 years for male patients. Among them, linear morphea was the most common type in this study (68 cases, 37.78%), followed by plaque morphea (63 cases, 35.00%), mixed morphea (28 cases, 15.56%) and deep morphea (21 cases, 11.67%). The disease occurred in all age groups, but the age at onset significantly varied among different clinical subtypes ( F = 5.95, P < 0.001). No significant difference was observed in the age at onset or proportion of clinical subtypes between genders ( F = 0.15, P = 0.696; χ2 =2.88, P = 0.410). Atrophoderma of Pasini and Pierini (APP) was very common (62 cases, 34.44%) in the 180 patients, which mainly manifested as plaques or linear lesions, and 26 out of 45 patients with plaque APP and 11 out of 17 with linear APP were both accompanied by other subtypes of morphea. Among the 75 patients tested for autoantibody profiles, 34 (45.33%) presented with positive results. More diverse types of autoantibodies were found in female patients compared with male patients, and antinuclear antibodies, anti-SSA and anti-SSB antibodies were the most common types. There were various types of comorbidities in female patients, but lichen sclerosus et atrophicus and vitiligo were the most common comorbidities in both genders. Conclusion:High incidence and frequent co-occurrence with other subtypes of APP may be the characteristics of Chinese patients with morphea, and it is recommended to classify morphea into plaque, linear, deep and mixed subtypes.

Taxane-induced scleroderma: report of two cases / Esclerodermia inducida por taxanos: informe de dos casos

ABSTRACT Taxanes are a class of chemotherapeutic agents with common associated dermatologic adverse events, such as skin hyperpigmentation, hand-foot skin syndrome, paronychia and onycholysis. Taxane-induced scleroderma is rare. Few cases with skin findings resembling systemic sclerosis, have been reported after the administration of these agents. We report two cases with stage IV breast cancer, aged 66 and 71 years, who developed sclerodermic skin lesions in their extremities after starting treatment with placlitaxel and nabplaclitaxel respectively.

Los taxanos son agentes quimioterapéuticos cuyo uso se asocia a problemas dermatológicos tales como hiperpigmentación, síndrome manos-pies, paroniquia y onicolisis. La esclerodermia inducida por taxanos es rara, con pocos casos informados en la literatura. Informamos los casos de dos pacientes con cáncer de mama en estado IV, de 66 y 71 años, que desarrollaron lesiones esclerodérmicas en las extremidades después de ser tratadas con placlitaxel y nabplaclitaxel, respectivamente.

A case report and literature review of cutaneous intravascular large B-cell lymphoma presenting clinically as panniculitis: a difficult diagnosis, but a good prognosis,

Abstract Intravascular large B-cell lymphoma is a rare, non-mass-forming, extranodal large B-cell lymphoma subtype characterized by the presence of tumor cells in the lumens of vessels. It is divided into two major types: classical and Asian. Patients presenting only with skin involvement are mostly female, at a younger age than classical intravascular large B-cell lymphoma patients, and have a better prognosis. Since the diagnosis of cases with isolated skin involvement is difficult, keeping this entity in mind, performing a careful microscopic examination, and applying new, effective treatment regimens will make it possible to achieve better clinical outcomes in these cases.

Endothelial lesion and complement activation in patients with Scleroderma Renal Crisis / Lesão endotelial e ativação do complemento em pacientes com crise renal esclerodérmica

Abstract In kidney biopsies reviews, scleroderma renal crisis (SRC) is characterized by vascular endothelial injuries, C4d deposits on peritubular vessels, and acute and chronic injuries coexisting on the same biopsy. The clinical signs of thrombotic microangiopathy (TMA) are described in systemic sclerosis (SSc), nevertheless, it has not been related to acute injuries described on kidney biopsies. We report a case of SRC in a patient with scleroderma-dermatomyositis overlap syndrome, which also showed clinical and histopathological data of TMA. On fundus examination, a severe acute hypertensive retinopathy was found. The kidney biopsy showed severe endothelial damage with widening of mucoid cells at the level of the intima, focal concentric proliferation on most small arterioles, and C3, C4d, and IgM deposits along the capillary walls. The genetic study of complement only showed the presence of membrane cofactor protein (MCP) risk haplotypes, without other genetic complement disorders. We understand that in a patient with TMA and SSc, the kidney damage would be fundamentally endothelial and of an acute type; moreover, we would observe clear evidence of complement activation. Once further studies correlate clinical-analytical data with anatomopathological studies, it is likely that we will be forced to redefine the SRC concept, focusing on the relationship between acute endothelial damage and complement activation.

Resumo Nas revisões de biópsias renais, a crise renal esclerodérmica (CRE) é caracterizada por lesões endoteliais vasculares, depósitos de C4d em vasos peritubulares e lesões agudas e crônicas que coexistem na mesma biópsia. Os sinais clínicos de microangiopatia trombótica (MAT) são descritos na esclerose sistêmica (ES); no entanto, não foram relacionados às lesões agudas descritas nas biópsias renais. Relatamos um caso de CRE em um paciente com síndrome de superposição de esclerodermia-dermatomiosite, que também apresentou dados clínicos e histopatológicos de MAT. No exame de fundo do olho, foi encontrada uma retinopatia hipertensiva aguda grave. A biópsia renal mostrou lesão endotelial grave com alargamento das células mucoides ao nível da íntima, proliferação concêntrica focal na maioria das pequenas arteríolas e depósitos de C3, C4d e IgM ao longo das paredes dos capilares. O estudo genético do complemento mostrou apenas a presença de haplótipos de risco da proteína cofator de membrana (PCM), sem outros distúrbios genéticos do complemento. Entendemos que em um paciente com MAT e ES, o dano renal seria fundamentalmente endotelial e do tipo agudo; além disso, observaríamos evidências claras de ativação do complemento. Uma vez que novos estudos correlacionam dados clínico-analíticos com estudos anatomopatológicos, é provável que sejamos forçados a redefinir o conceito de CRE, enfocando a relação entre dano endotelial agudo e ativação do complemento.

Combined high-frequency and Doppler ultrasound in early diagnosis of atrophoderma of Pasini and Pierini

Abstract: Atrophoderma of Pasini and Pierini is a skin disorder affecting dermal collagen and is clinically characterized by well-defined plaques of depressed skin. Histopathological changes are subtle, and in most cases, the diagnosis requires a comparative study with healthy skin from the same anatomical site. High frequency ultrasound is a useful imaging method for diagnosis of atrophic skin changes. A case is presented in which ultrasound can support the clinical and the histopathological diagnosis of atrophoderma of Pasini and Pierini.

Case for diagnosis. Sclerodermiform manifestations of porphyria cutanea tarda secondary to hepatitis C

Abstract: A 63-year-old black female patient with blisters and exulcerations on the face, neck, upper limbs, and subsequent evolution with hypochromic sclerotic areas and alopecia, is reported. Chronic hepatitis C and presence of high levels of porphyrins in urine were demonstrated. There was complete remission with the use of hydroxychloroquine, photoprotection, and treatment of hepatitis. Significant sclerodermoid involvement of the skin as a manifestation of porphyria cutanea tarda secondary to hepatitis C emphasizes the importance of diagnostic suspicion regarding skin manifestation in order to indicate the appropriate therapy, and to minimize the hepatic morbidity.

Coexistence of morphea and granuloma annulare: a rare case report

ABSTRACT CONTEXT: Localized scleroderma (morphea) is characterized by fibrosis of skin and subcutaneous tissue. Granuloma annulare is a relatively common disease that is characterized by dermal papules and arciform plaques. CASE REPORT: Here, we present the case of a 42-year-old woman who developed granuloma annulare on the dorsum of her feet and abdominal region, and morphea on the anterior side of her lower limbs. We also discuss the etiological and pathogenetic processes that may cause the rare coexistence of these two diseases. CONCLUSION: Only a few cases in the literature have described coexistence of morphea and granuloma annulare.

Clinicopathological analysis of six cases of disabling pansclerotic morphea / 中华皮肤科杂志

Objective To investigate clinical and pathological features of 6 cases of disabling pansclerotic morphea (DPM).Methods Clinical and pathological manifestations of and follow-up results in 6 patients,who were clinically and histopathologically diagnosed with DPM in the Department of Pathology,Hospital for Skin Diseases,Chinese Academy of Medical Sciences and Peking Union Medical College from 2007 to 2017,were retrospectively analyzed.Results Among the 6 patients,4 were male and 2 were female.The age of onset ranged from 3 to 10 years,with an average age of 6.5 years.The average duration from the occurrence to the confirmation of the diagnosis was 6.2 years (range,2-10 years).At all the lesional sites,skin atrophy,thining and tightness occurred,and the limbs became thin.Additionally,there were muscular atrophy and visible deep thick veins on the surface of the limbs.The contracture,deformity and dysfunction of the adjacent joints occurred in 4 cases,and the lower limbs were obviously shortened in 2 cases.Peripheral blood examination showed no increase of eosinophils or hypergammaglobulinemia.Imaging examination revealed smooth cortical bone and clear trabecular bone,and no osseous abnormality was observed.Histopathological examination of contracted skin lesions of the lower limbs revealed atrophic and thinned epidermis,hyperpigmentation in the basal layer,hyperplastic,thickened,hardened and partly homogenized collagen fibers in the middle to deep dermis,subcutaneous adipose tissue region and deep tissue of the skin.Conclusions DPM usually does not affect viscera,but often involves deep tissue of the limbs.Histopathologically,DPM is mainly characterized by obviously hyperplastic and hardened collagen fibers in the dermis and subcutaneous tissue.

Evaluation of mean platelet volume in localized scleroderma

Abstract: Background: Localized scleroderma is a chronic inflammatory skin disease characterized by sclerosis of the dermis and subcutaneous tissue. Platelets play an important role in inflammation. Following activation, platelets rapidly release numerous mediators and cytokines, which contribute to inflammation. Objectives: To evaluate whether there was any relation between localized scleroderma and platelet parameters. Methods: Forty-one patients with localized scleroderma were enrolled in the study. The control group consisted of 30 healthy subjects. Results: The mean platelet volume level in the patient group was 9.9 ± 1.3 fl and in the control group was 7.6 ± 1.1 fl. This difference was statistically significant (p< 0.001). The plateletcrit values are minimally higher in the patient group as compared to the control group. It was statistically significant (p<0.001). There was no significant difference in the platelet counts between the two groups (p= 0.560) In the patient group, there was no significant relation between the mean platelet volume levels and clinical signs of disease (p=0.09). However, plateletcrit values are higher in generalized than localized forms of disease (p=0.01). Study Limitations: The limited number of patients and the retrospective nature of the study were our limitations. Conclusions: This study suggests that platelets might play a role in the pathogenesis of scleroderma. Platelet parameters may be used as markers for evaluating disease severity and inflammatory processes. Thus, there is a need for more detailed and prospective studies.

Morfea mamaria. Presentación de un caso / Breast Morphea. Case Presentation

La esclerodermia localizada es la forma localizada cutánea de esclerodermia, caracterizada por una fibrosis que se manifiesta en forma de placas o bandas cutáneas escleróticas infiltradas al tacto. La prevalencia se estima en aproximadamente 1-9/100.000, por tal razón se presenta el caso de una paciente con manifestaciones de una esclerodermia cutánea localizada cuya lesión apareció en una mama dos meses antes de asistir a consulta en su área de salud. La principal lesión que presentaba era una placa áspera, que no se dejaba pellizcar, de color carmelita, bordes irregulares, de aproximadamente seis centímetros de diámetro, localizada en mitad inferior de la mama derecha, incluyendo pezón y areola. Se detectaron las alteraciones histológicas propias de la enfermedad de base lo que corroboró el diagnóstico planteado y se descartó mediante otros exámenes cualquier presencia de proceso maligno.

Dental treatment requires a comprehensive management by professionals who understand oral pathologies and permanent characteristic symptoms of systemic disease. The aim of this paper is to present two cases of scleroderma highlighting present oral manifestations.

Do you know this syndrome? Werner syndrome

Abstract: Werner syndrome is a rare autosomal recessive disorder, caused by mutations in the WRN gene. Clinical findings include: senile appearance, short stature, grey hair, alopecia, bird-like face, scleroderma-like skin changes, skin ulcers, voice abnormalities, cataracts, osteoporosis, type 2 diabetes mellitus, ischemic heart disease and hypogonadism. The syndrome begins to become apparent in adolescence but it is usually diagnosed in the third or fourth decade of life. Since the patients usually die by the age of 40-50 years related to malignant neoplasms or atherosclerotic complications, they should be closely followed and treated for complications

A case of systemic sclerosis sine scleroderma and a literature review / 中华风湿病学杂志

Objective Systemic sclerosis sine scleroderma (ssSSc) is a rare type of systemic sclerosis,comparison between ssSSc and other types of systemic sclerosis (SSc),ssSSc is carried out in this study.Methods We reported a patient with Raynand's phenomenon,esophagus,intestine and lung involvement,positive ANA,anti-Scl-70 antibody,but had no skin sclerosis.Results For visceral involvement,ssSSc was not different from limited cutaneous systemic sclerosis (lcSSc),The incidence of pulmonary hypertension was higher in patients with ssSSc,lower with calcinosis,finger ulcer and acral dissolution,and the incidence of ssSSc and lcSSc interstitial lung disease was higher than that of diffuse cutaneous systemic sclerosis,(dcSSc).Conclusion Although ssSSc do not have skin sclerosis,however,visceral involvement is more extensive.Early diagnosis and treatmeat is extremely important.

Lichen sclerosus associated with localized scleroderma: dermoscopy contribution

Abstract: Lichen sclerosus is an uncommon inflammatory dermatosis with preferential involvement of the urogenital region. The extragenital involvement is uncommon and is characterized by small rounded macules or papules, pearly white in color. The coexistence of lichen sclerosus and scleroderma plaques in most cases with extragenital location has been reported in the literature. We report a case of lichen sclerosus associated with scleroderma in children, highlighting the importance of dermoscopy in diagnosis.
