ABSTRACT

Löfgren syndrome (LS) is a unique acute manifestation of sarcoidosis and characterized by erythema nodosum, bilateral hilar lymphadenectasis, and/or bilateral ankle arthritis or periarthritis. A 37 - year - old female patient with LS presented with fever accompanied by multiple joint swelling and pain, nodular skin erythema, and bilateral hilar lymphadenectasis. The patient had received treatment involving non - steroidal anti - inflammatory drugs and glucocorticoids in other hospitals, but the effects were poor, and the conditions reemerged. The LS duration has lasted for more than 3 months. Following traditional Chinese medicine (TCM) treatment, syndrome differentiation as well as giving patients oral Chinese medicine decoction, the symptoms of the patient were rapidly relieved within one week and did not recur during a six - month follow - up period. This case is the first clinical report of acute sarcoidosis LS treated using T CM and reflects the significant advantages of this form of therapy in emergency treatment


El síndrome de Löfgren (LS) es una manifest ación única y aguda de sarcoidosis, caracterizada por eritrema nodoso, linfadenectasis hilar bilateral, y/o a r tritis de tobillo bilateral o periartritis. Una paciente de 37 años de sexo femenino con LS se presentó con fiebre, acompañada de inflamación y do lor múltiple de articulaciones, eritrema nodular cutáneo, y linfadenectasis hilar bilateral. La paciente recibió un tratamiento que consistió en antiinflamatorios no esteroidales y glucocorticoides en otros hospitales, pero los efectos fueron leves y las c ondiciones reemergieron. El LS ha durado más de tres meses. Siguiendo el tratamiento de medicina tradicional china (MTC), la diferenciación de síndrome, así como darles a los pacientes una decocción de medicina china por vía oral, los síntomas de la pacien te rápidamente fueron aliviados en el curso de una semana y no recidivaron durante los seis meses de un seguimiento. El caso es el primer reporte clínico de tratamiento de sarcoidosis aguda asociada a LS usando TCM y refleja las significativas ventajas de esta forma de terapia en el tratamiento de emergencia.

ABSTRACT

La neuroinmunología es una disciplina que cada vez amplía más sus horizontes en la comprensión de las enfermedades neurológicas. Contemporáneamente, y a la luz de los nexos fisiopatológicos de las enfermedades neurológicas y la inmunología, se han planteado enfoques diagnósticos y terapéuticos específicos. A pesar de los importantes avances de esta disciplina, existen múltiples dilemas que le conciernen y se filtran en la práctica clínica. En esta revisión, se presentan y discuten 15 controversias, las cuales se construyen con la información clínica disponible más actualizada. Los temas incluidos son: disminución de esteroides en recaídas de esclerosis múltiple; recomendaciones terapéuticas en esclerosis múltiple a la luz de la pandemia por el SARS-CoV-2; evidencia de vacunación en esclerosis múltiple y en otras enfermedades desmielinizantes; panorama actual del síndrome clínico y radiológico aislado; y fallas terapéuticas en esclerosis múltiple; además, criterios para suspender las terapias modificadoras de la enfermedad; evidencia del manejo en recaídas leves; recomendaciones para la profilaxis contra Strongyloides stercolaris; utilidad de un segundo ciclo de inmunoglobulina en el síndrome de Guillain-Barré; criterios para diferenciar una polineuropatía crónica desmielinizante inflamatoria de inicio agudo de un síndrome de Guillain-Barré y, utilidad de la enzima convertidora de angiotensina en neurosarcoidosis. En cada una de las controversias, se presenta la problemática general y se ofrecen recomendaciones específicas que pueden adoptarse en la práctica clínica diaria.


Neuroimmunology is a discipline that increasingly broadens its horizons in the understanding of neurological diseases. At the same time, and in front of the pathophysiological links of neurological diseases and immunology, specific diagnostic and therapeutic approaches have been proposed. Despite the important advances in this discipline, there are multiple dilemmas that concern and filter into clinical practice. This article presents 15 controversies and a discussion about them, which are built with the most up-to-date evidence available. The topics included in this review are: steroid decline in relapses of multiple sclerosis; therapeutic recommendations in MS in light of the SARS-CoV-2 pandemic; evidence of vaccination in multiple sclerosis and other demyelinating diseases; overview current situation of isolated clinical and radiological syndrome; therapeutic failure in multiple sclerosis, as well as criteria for suspension of disease-modifying therapies; evidence of the management of mild relapses in multiple sclerosis; recommendations for prophylaxis against Strongyloides stercolaris; usefulness of a second course of immunoglobulin in the Guillain-Barré syndrome; criteria to differentiate an acute-onset inflammatory demyelinating chronic polyneuropathy versus Guillain-Barré syndrome; and, the utility of angiotensin-converting enzyme in neurosarcoidosis. In each of the controversies, the general problem is presented, and specific recommendations are offered that can be adopted in daily clinical practice.

ABSTRACT

Introduction: Epidemiological studies on sarcoidosis in Colombia are scarce, and although recent reports from the north of the country have been published, clinical-epidemiological associations are not clear. Our aim was to characterize patients with sarcoidosis diagnosed at Fundación Valle del Lili in Cali, Colombia. Methods: A retrospective study of a series of sarcoidosis cases was conducted between 2011 and 2019. Demographic, clinical, laboratory, imaging, histopathological, and treatment variables were analyzed. Results: A total of 34 patients with a diagnosis of sarcoidosis were found. The majority were women (n = 25; 73%), and the mean age was 50 years. The main symptoms of onset were erythema nodosum (n = 11; 33%), arthritis (n = 10; 30%), and cough (n = 9; 27%). In 64% of the cases, there was pulmonary involvement, with pulmonary nodules, mediastinal adenopathy, and interstitial lung disease found in 54%, 50%, and 36% of cases, respectively. In 85% of cases, there were extrapulmonary manifestations, mainly cutaneous (50%). Angiotensin-converting enzyme (ACE) was elevated in 62% of the cases in which it was measured (n = 16; 47%). During the diagnostic process, 23 biopsies were performed, of which 95% showed granulomas with noncaseating necrosis. Most of the patients (76%) were controlled with prednisolone, at an average dose of 20 mg (7.5-50 mg) per day. Conclusions: Sarcoidosis was more frequent in women and mestizos, and it presented earlier in men. Elevated ACE was not associated with extrapulmonary involvement. Calcium-phosphorus profile and antinuclear antibodies were not useful to establish the diagnosis.


Introducción: En Colombia son escasos los estudios epidemiológicos sobre la sarcoidosis; aunque recientemente se han publicado reportes del norte del país, son grupos muestrales pequeños, por lo que no quedan claras las asociaciones clínico-epidemiológicas. Nuestro objetivo fue caracterizar pacientes con sarcoidosis en la Fundación Valle del Lili, en Cali, Colombia. Métodos: Se realizó un estudio retrospectivo de una serie de casos de sarcoidosis entre el 2011 y el 2019. Se analizaron variables demográficas, clínicas, de laboratorio, imagenológicas, histopatológicas y de tratamiento. Resultados: Se encontraron 34 pacientes con diagnóstico de sarcoidosis, la mayoría fueron mujeres (n = 25; 73%), y la edad promedio fue 50 anos. Los principales síntomas de inicio fueron eritema nudoso (n = 11; 33%), artritis (n = 10; 30%) y tos (n = 9; 27%). En el 64% de los casos hubo compromiso pulmonar, y se encontraron nódulos pulmonares, adenopatías mediastinales y enfermedad pulmonar intersticial en un 54, 50 y 36% de los casos, respectivamente. En el 85% de los casos hubo manifestaciones extrapulmonares, principalmente cutáneas (50%). Los niveles de enzima conversora de angiotensina estuvieron elevados en el 62% de los casos en los que fue medida (n = 16; 47%). Durante el proceso diagnóstico se realizaron 23 biopsias, de las cuales el 95% evidenció granulomas con necrosis no caseificante. La mayoría de los pacientes (76%) fueron controlados con prednisolona, a una dosis promedio de 20 mg (7,5-50 mg) por día. Conclusiones: La sarcoidosis fue más frecuente en mujeres y mestizos. La presentación fue más temprana en hombres. La enzima conversora de angiotensina no se relacionó con compromiso extrapulmonar. Ni el perfil fósforo-calcio ni los anticuerpos antinucleares fueron útiles para establecer el diagnóstico.

ABSTRACT

ABSTRACT Sarcoidosis is a multi-system disease that involves the lung in 90% of cases. Skeletomuscular involvement of sarcoidosis may involve joints, muscles and/or bones, the latter affecting 313% of patients. Its clinical presentation is asymptomatic in half of the cases, in the other half there is pain, soft tissue edema, and decreased limb function. Radiographically it is accompanied by osteolysis, osteosclerosis, cystic lesions and pathological fractures in advanced stages. A final diagnosis is made by tissue biopsy, finding non-caseating granulomatous process accompanied by Langhans giant cells. The main indication of medical management is the control of symptoms, associated with an improvement in the functioning of the affected limb and quality of life of the patient. The case is presented of a patient with digital sarcoidosis with classic radiographic pattern with no other extra-skeletal involvement.


RESUMEN La sarcoidosis es una enfermedad multisistémica que involucra en el 90% de los casos el pulmón. El compromiso osteomuscular de la sarcoidosis puede incluir articulaciones, músculos o huesos; este último caso afecta al 3-13% de los pacientes. Su presentación clínica es asintomática en la mitad de los casos, el restante se presenta con dolor, edema de tejidos blandos y disminución en la funcionalidad de la extremidad. Radiográficamente se acompaña de osteólisis, osteoesclerosis, lesiones quísticas y fracturas patológicas en estadios avanzados. Su diagnóstico definitivo se realiza por medio de una biopsia tisular, en la que se encuentra un proceso granulomatoso no caseificante acompañado de células gigantes de Langhans. La principal indicación del manejo médico es el control de los síntomas, lo que se asocia con una mejoría en el funcionamiento de la extremidad afectada y en la calidad de vida del paciente. Se presenta el caso de un paciente con sarcoidosis digital con patrón radiográfico clásico, sin otro compromiso extraesquelético.

ABSTRACT

La alogenosis iatrogénica es la enfermedad causada por la aplicación de biopolímeros con fines estéticos. Sus manifestaciones clínicas pueden presentarse entre las seis horas y los 30 años posteriores a la aplicación, con síntomas locales o sistémicos. El principal rasgo de la histopatología es la presencia de granulomas por cuerpo extraño con reacción de tipo sarcoideo, la cual es difícil de Interpretar por su asociación con la sarcoidosis. Se reporta aquí el caso de una paciente con lesiones granulomatosas de tipo sarcoideo por reacción a cuerpo extraño, secundaria a la aplicación de múltiples sustancias desconocidas en cara y glúteos.


Iatrogenic allogenosis is a disease caused by the injection of biopolymers with esthetic purposes. Clinical manifestations can occur between six hours and 30 years after the procedure with local and/or systemic symptoms. The pathological findings are characterized by the presence of foreign body granulomas with a sarcoid-like reaction. Its Interpretation Is difficult given Its association with sarcoidosis. We report the clinical case of a female patient with granulomatous lesions In reaction to a foreign body secondary to the multiple application of unknown substances on the face and buttocks.

ABSTRACT

Introduction There are some inflammatory, infectious, and neoplastic diseases affecting the extrinsic orbital musculature (EOM) that present with pain, decreased visual acuity, and proptosis. Imaging is fundamental to the differential diagnoses of these diseases with similar clinical presentations. The present case series report has as main objective to illustrate and discuss the main pathologies that affect the orbit. Material and Methods The present series of cases discusses the main pathologies that can affect the extraocular musculature that can be characterized by computed tomography (CT) or magnetic resonance imaging (MRI) using cases from our institution. Results and Discussion The present study compiled several cases of ophthalmopathy from our institution to illustrate and address some of these pathologies, such as orbital lymphoma, Grave disease, metastases, periorbital cellulitis, and idiopathic orbital inflammatory syndrome. The diseases are discussed according to the presentation of clinical cases with emphasis on the main imaging findings of each pathology. Conclusion Computed tomography and MRI can help in the diagnosis and follow-up of the diseases that affect the EOM. We must be conversant with the main characteristics of the pathologies presented in the present case series report, since such findings together with clinical data can confirm the diagnosis of these diseases or at least help to narrow the differential diagnoses.

ABSTRACT

La sarcoidosis es una enfermedad multisistémica presente a nivel mundial que se caracteriza por el compromiso pulmonar y mediastinal en la mayoría de los pacientes. Para confirmar el diagnóstico, es importante contar con una biopsia que demuestre granulomas no caseificantes y la exclusión de otros diagnósticos diferenciales. Por lo tanto, la selección del método diagnostico para la confirmación histológica juega un rol fundamental en estos pacientes. Es así como, en los últimos años, el ultrasonido endoscópico bronquial (EBUS) ha mostrado ser un método seguro y con un alto rendimiento diagnóstico que debe considerarse en el abordaje de esta patología cuando existe compromiso mediastinal.


Sarcoidosis is a multisystemic disease present worldwide that is characterized by pulmonary and mediastinal involvement in most patients. To confirm the diagnosis, it is important to have a biopsy showing non-caseating granulomas and the exclusion of other differential diagnoses. Therefore, the selection of the diagnostic method for histological confirmation plays a fundamental role in these patients. Thus, in recent years, endoscopic bronchial ultrasound (EBUS) has shown to be a safe method with a high diagnostic yield that should be considered in the approach to this pathology when there is mediastinal involvement.

ABSTRACT

Background. Sarcoidosis is a multisystem granulomatous disorder. Its exact cause is unknown, but it is believed that an external agent may cause the characteristic immune reaction in genetically susceptible individuals. There is therefore general recognition that genetic vulnerability to sarcoidosis is one of the potential risk factors. HLA is encoded by genes in the major histocompatibility complex on chromosome 6. These surface cells are important in presentation of antigen and play a key part in the body's immune response to external antigens. Various HLA subtypes are more common in people with sarcoidosis than in those without. Variances in vulnerability, presentation, progression and prognosis have been related to different HLA phenotypes. HLA genes offer information into the factors driving sarcoidosis and prognosticating tools. However, in Africa, including South Africa (SA), there are no data on HLA types in relation to sarcoidosis.Objectives. To determine HLA class I and II associations in SA sarcoidosis patients.Methods. Phenotype frequencies of HLA-A, B and C and DQB1 and DRB1 were calculated for 51 consecutive patients with biopsy-proven sarcoidosis attending the respiratory clinic at Charlotte Maxeke Johannesburg Academic Hospital and 63 controls, who were potential organ donors. The frequencies of the tested HLA loci were determined by direct counting. The significance of the associations between the various loci tested for and the presence or absence of sarcoidosis was estimated from 2 × 2 tables using the χ2 test.Results. Of the 51 patients, 70.6% were female. The mean age was 44.6 years. Analysis of HLA class I and class II phenotypes in sarcoidosis patients revealed a significant association with HLA-B15, C4, C7, C12, C15, C16, C17, DQ3, DR8 and DR11. In addition, a significant negative (protective) association with HLA A9, A28, B12, B17 and DR2 was observed.Conclusion. This HLA study in SA patients suggests that genetic factors play a role in the causation of sarcoidosis. Some HLA subtypes have a significant association with sarcoidosis in SA patients, while other subtypes may be protective. The study supported the association of HLA antigens with sarcoidosis and implies that there is a genetic predisposition to sarcoidosis in the SA population.

ABSTRACT

Se comunica una serie de tres casos clínicos que consultaron al servicio de Reumatología por compromiso orbitario y renal. Uno de ellos presentó pseudotumor orbitario con proteinuria en rango nefrótico; se realizó biopsia y se encontró infiltrado linfoplasmocitario denso y fibrosis estoriforme con inmunohistoquímica: 15 células IgG4+ por campo de alto poder y relación IgG/IgG4 ≤40%, concluyendo diagnóstico de enfermedad relacionada por IgG4. El segundo y tercer caso presentaron compromiso ocular con "ojos de mapache" y lesiones amarillentas en párpados, ambos con proteinuria >500 mg/24 h, con biopsia de piel rojo Congo positiva y birrefringencia verde manzana con luz polarizada. Se discuten distintos diagnósticos diferenciales poco frecuentes a tener en cuenta en estos pacientes.


A series of three cases that consulted the rheumatology service due to orbital and renal involvement is reported. One of them presented orbital pseudotumor with proteinuria in the nephrotic range, a biopsy was performed, finding dense lymphoplasmacytic infiltrate and storiform fibrosis with immunohistochemistry: 15 IgG4 positive cells per HPF and IgG/IgG4 ratio ≤40%, concluding diagnosis of IgG4 related disease. The second and third cases presented ocular involvement with raccoon eyes and yellowish lesions on the eyelids, both with proteinuria greater than 500 mg/24 h, with apple-green birefringence of amyloid on congo red staining. Different rare differential diagnoses to take into account in these patients are discussed.

ABSTRACT

Introducción: La sarcoidosis es una enfermedad inflamatoria, granulomatosa de etiología desconocida. Puede afectar cualquier órgano siendo la afectación pulmonar la más frecuente. La piel se compromete en aproximadamente 30% de los casos, pudiendo ser inicial o único. La sarcoidosis es muy rara en el Paraguay. Objetivos: Realizar una revisión de los casos de sarcoidosis observados en el Servicio de Dermatología del Hospital Nacional en el periodo 2010-2020; determinando sus características demográficas, clínicas, laboratoriales y evolutivas. Materiales y métodos: Estudio retrospectivo, descriptivo y observacional. Resultados: Se diagnosticaron 5 casos, todas mujeres de raza blanca, con edades que oscilaban de 41 a 63 años. Las formas clínicas fueron papulosa en 3 casos, en placa 1 y mixta 1. Las lesiones cutáneas eran asintomáticas y estaban ubicadas preferentemente en rostro (4 casos). El compromiso sistémico se objetivó en las primeras consultas en 2 casos (pulmonar, ocular y ganglionar en 1 y del aparato lagrimal en otro). En todos los casos el diagnóstico se fundamentó en la correlación clínico-histológica, con el hallazgo de los granulomas sarcoides. Todos recibieron clobetasol tópico, 3 pacientes ciclos de prednisona y 2 hidroxicloroquina. La evolución fue favorable en 3 casos y 2 no volvieron a sus controles. Conclusión: La sarcoidosis con manifestaciones cutáneas es rara en nuestro Servicio, pero representa un desafío diagnóstico, que debe ser oportuno para diferenciarla de otras patologías más prevalentes en nuestro medio


Introduction: Sarcoidosis is an inflammatory, granulomatous disease of unknown etiology. It can affect any organ, lung involvement being the most frequent. The skin is compromised in approximately 30% of the cases, and can be initial or unique. Sarcoidosis is very rare in Paraguay. Objectives: To carry out a review of the sarcoidosis cases observed in the Dermatology Service of the National Hospital in the period 2010-2020; determining their demographic, clinical, laboratory and evolutionary characteristics. Materials and methods: Retrospective, descriptive and observational study. Results: 5 cases were diagnosed; all white women; with ages ranging from 41 to 63 years. The clinical forms were papular in 3 cases, in plate 1 and mixed 1. The skin lesions were asymptomatic and were preferably located on the face (4 cases). Systemic involvement was observed in the first consultations in 2 cases (pulmonary, ocular and lymph node in 1 and the lacrimal apparatus in another). In all cases the diagnosis was based on the clinical-histological correlation, with the finding of sarcoid granulomas. All received topical clobetasol, 3 patients received prednisone cycles and 2 hydroxychloroquine. The evolution was favorable in 3 cases and 2 did not return to their controls. Conclusion: Sarcoidosis with skin manifestations is rare in our Service, but it represents a diagnostic challenge that must be timely to differentiate it from other more prevalent pathologies in our setting

ABSTRACT

Sarcoidosis is a systemic disease characterized by granulomatous inflammation. Pulmonary and lymphatic granulomatous involvement are common.We present a rare case report of involvement of the central nervous system affecting the ocular region and mimicking optic nerve sheath meningioma. We report the case of a 79-year-old female patient with progressive visual impairment with an evolution of 4 years. Amagnetic resonance imaging scan of the cranium with gadolinium and intense homogeneous contrast enhancement revealed an expansive lesion in the right optic nerve, at the height of the optic canal. The patient was submitted to the neurosurgical approach with lesion biopsy, which showed sarcoidosis of the central nervous system. Due to the rarity of central nervous system involvement, the diagnosis of this pathologymay unfortunately be postponed. The present article aims to elucidate this pathology as a differential diagnosis of retro-orbital tumors.

ABSTRACT

RESUMEN La sarcoidosis es una enfermedad granulomatosa, multisistémica, de causa desconocida y con múltiples manifestaciones clínicas. La característica histopatológica esencial son los granulomas uniformes no caseificantes con escasos linfocitos periféricos (granulomas desnudos). Se presenta el caso de un paciente masculino de 62 años que acudió a Cuerpo de Guardia por presentar tos seca, falta de aire, inflamación de ganglios axilares y lesiones en piel, en forma de placas, máculas y otras de aspecto psoriasiforme. Las manifestaciones clínicas, los resultados de los exámenes complementarios y al hacer el diagnóstico diferencial con otras afecciones que cursan con hallazgos similares, se llegó al diagnóstico de sarcoidosis sistémica. El paciente evolucionó favorablemente con el tratamiento indicado. El compromiso cutáneo de la sarcoidosis representa un desafío dada la variada presentación de esta entidad y los diagnósticos diferenciales a considerar.


ABSTRACT Sarcoidosis is a multisystemic granulomatous disease of unknown etiology with multiple clinical manifestations. The essential histopathologic feature is uniform non-caseating granulomas with few peripheral lymphocytes (naked granulomas). We present the case of a 62-year-old male patient who came to the emergency room due to a dry cough, shortness of breath, swollen axillary glands and skin lesions, in the form of plaques, macules, and others with a psoriasiform appearance. The clinical manifestations, the results of the complementary tests and when making the differential diagnosis with other conditions that present similar findings, the diagnosis of systemic sarcoidosis was reached. The patient evolved favorably with the indicated treatment. The cutaneous involvement of sarcoidosis represents a challenge given the varied presentation of this entity and the differential diagnoses to be considered.

ABSTRACT

Abstract PTH-independent hypercalcemia due to granulomatous disease is well-documented and sarcoidosis is the most characteristic disease, although there are others. We describe a case of sarcoid-like granulomatous myositis. An 87-year-old man was referred with tetraparesis and hypercalcemia (albumin-corrected calcium of 13.4 mg/dl) following a trip to the Caribbean. The evaluation showed a suppressed PTH, 25-hydroxy vitamin D of 7.5 ng/ml, 18F-FDG PET/CT showed markedly increased uptake in intercostal, back, shoulder, but tock and thigh muscles and a deltoid biopsy confirmed extensive granulomatous myositis. He was prescribed glucocorticoids which resulted in normalized plasma calcium levels and complete recovery from tetraparesis. Sarcoid-like granulomatous myositis should be incorporated into the differential diagnosis of PTH-independent hypercalcemia, especially in the absence of clinical features of sarcoidosis and with special emphasis on the use of 18F-FDG PET/CT to ensure a correct approach.


Resumen La hipercalcemia PTH-independiente asociada a enfermedades granulomatosas está bien documentada y la sarcoidosis es la enfermedad más característica, a pesar de que existen otras. Des cribimos un caso de miositis granulomatosa simil-sarcoidea. Un hombre de 87 años consultó por tetraparesia e hipercalcemia (calcio corregido por albúmina 13.4 mg/dl) luego de un viaje al Caribe. La evaluación mostró una PTH suprimida, 25-hidroxivitamina D 7.5 ng/ml, 18F-FDG PET/CT mostró marcado aumento de captación a nivel de musculatura intercostal, dorsal, deltoidea, glúteos y muslos. Una biopsia deltoidea confirmó una miositis granulomatosa extensa. Se prescribieron glucocorticoides, resultando en normalización del calcio plasmático y completa recuperación de la tetraparesia. La miositis granulomatosa simil-sarcoidea debe ser incorporada den tro del diagnóstico diferencial de la hipercalcemia PTH-independiente, especialmente en ausencia de hallazgos clínicos de sarcoidosis y con especial énfasis en el uso de 18F-FDG PET/CT para su correcta aproximación.

ABSTRACT

ABSTRACT Objective: Evaluation of enlarged mediastinal lymph nodes is crucial for patient management. Malignant lymphoma and sarcoidosis are often difficult to differentiate. Our objective was to determine the diagnostic accuracy of MRI for differentiating between sarcoidosis and malignant lymphoma. Methods: This was a retrospective study involving 47 patients who underwent chest MRI and were diagnosed with one of the diseases between 2017 and 2019. T1, T2, and diffusion-weighted signal intensity were measured. Apparent diffusion coefficients (ADCs) and T2 ratios were calculated. The diagnostic performance of MRI was determined by ROC analysis. Results: Mean T2 ratio was significantly lower in the sarcoidosis group than in the lymphoma group (p = 0.009). The T2-ratio cutoff value that best differentiated between lymphoma-related and sarcoidosis-related enlarged lymph nodes was 7.1, with a sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 58.3%, 95.6%, 76.5%, 93.3%, and 68.7%, respectively. The mean ADC was significantly lower in the lymphoma group than in the sarcoidosis group (p = 0.002). The ADC cutoff value that best differentiated between lymphoma-related and sarcoidosis-related enlarged lymph nodes was 1.205, with a sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 87.5%, 82.6%, 85.1%, 84.0% and 86.3%, respectively. No significant differences were found between the two groups regarding T1 signal intensity, T2 signal intensity, and lymph node diameter. Conclusions: MRI parameters such as ADC, diffusion, and T2 ratio can be useful in the differentiation between sarcoidosis and lymphoma in the evaluation of enlarged lymph nodes.


RESUMO Objetivo: A avaliação de linfonodomegalias mediastinais é crucial para o manejo dos pacientes. O linfoma maligno e a sarcoidose costumam ser difíceis de diferenciar. Nosso objetivo foi determinar a precisão diagnóstica da RMN para diferenciar sarcoidose de linfoma maligno. Métodos: Estudo retrospectivo com 47 pacientes submetidos a RMN de tórax e diagnosticados com uma das doenças entre 2017 e 2019. Foi medida a intensidade do sinal em T1, T2 e difusão. Foram calculados o coeficiente de difusão aparente (ADC, do inglês apparent diffusion coefficient) e a razão T2. O desempenho diagnóstico da RMN foi determinado pela análise da curva ROC. Resultados: A média da razão T2 foi significativamente menor no grupo sarcoidose que no grupo linfoma (p = 0,009). A razão T2 = 7,1 foi o melhor valor de corte para diferenciar linfonodomegalias relacionadas com linfoma daquelas relacionadas com sarcoidose, com sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e precisão de 58,3%, 95,6%, 76,5%, 93,3% e 68,7%, respectivamente. A média do ADC foi significativamente menor no grupo linfoma que no grupo sarcoidose (p = 0,002). O ADC = 1,205 foi o melhor valor de corte para diferenciar linfonodomegalias relacionadas com linfoma daquelas relacionadas com sarcoidose, com sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e precisão de 87,5%, 82,6%, 85,1%, 84,0% e 86,3%, respectivamente. Não houve diferença significativa entre os grupos quanto à intensidade do sinal em T1, intensidade do sinal em T2 e diâmetro dos linfonodos. Conclusões: Parâmetros de RMN como ADC, difusão e razão T2 podem ser úteis na diferenciação entre sarcoidose e linfoma na avaliação de linfonodomegalias.

ABSTRACT

Summary@#Sarcoidosis is a multisystem disease characterised by granulomatous inflammation possibly due to hyperactivation of the immune system; with unknown etiology. Subcutaneous sarcoidosis (also known as Darier Roussy sarcoid) is a rare type of specific cutaneous lesion of sarcoidosis characterised by multiple firm, asymptomatic to mildly tender, mobile, round to oval, and skin coloured nodules. Herein we report a rare case of subcutaneous sarcoidosis.
