Abordaje de la enfermedad de Behçet vulvar: comunicación de caso

La enfermedad de Behçet (EB) es un trastorno inflamatorio, multisistémico, recidivante y remitente de etiología desconocida. Una característica clave de la enfermedad es la ulceración orogenital que provoca una morbilidad considerable con gran impacto en la calidad de vida de los pacientes. Su manejo médico consiste en un esquema con colchicina, esteroides o inmunomoduladores. Comunicamos el caso de una paciente con lesiones genitales quien consultó en múltiples ocasiones, recibiendo manejo antibiótico e incluso quirúrgico, con respuesta refractaria a estas intervenciones. Posteriormente, por las características de las lesiones y el comportamiento clínico se sospechó enfermedad de Behçet y se instauró manejo médico con esteroides orales y curaciones con fitoestimulina. Hubo resolución de las úlceras genitales y posteriormente la paciente fue llevada a cirugía para corrección de las sinequias vulvares.

Behçet's disease (BD) is an inflammatory, multisystemic, relapsing-remitting disorder of unknown etiology. A key feature of the disease is orogenital ulceration that causes considerable morbidity with great impact on patient's quality of life. Its medical management consists of a scheme with colchicine, steroids or immunomodulators. We report the case of a patient with genital lesions who consulted on multiple occasions, receiving antibiotics and even surgical management, with refractory response to these interventions. Subsequently, due to the characteristics of the lesion and clinical behavior, Behçet's disease was suspected and medical management with oral steroids and cures with phytostimulin was initiated. The genital ulcers were resolved, and the patient was subsequently taken to surgery for correction of the vulvar synechiae.

Systemic disease in leukocytoclastic vasculitis: a focus on direct immunofluorescence findings

Abstract Background Direct immunofluorescence (DIF) panels are usually ordered for clinically suspected cutaneous vasculitis, but their positivity rate is variable, and their prognostic significance is not clear to date. Objective The study aims to investigate the systemic involvement rate in leukocytoclastic vasculitis (LCV) patients and the potential clinical and laboratory associations with systemic involvement, including DIF findings. Methods A retrospective study of patients with histopathologically proven cutaneous LCV examined in the dermatology department between 2013 and 2017 was performed. Results Of the 81 patients (mean age, 50.6 years), 42 (52%) were male. The mean time between the appearance of skin lesions and biopsy was 23.1 days, ranging from 2 to 180 days. DIF showed overall positivity of 90.1%, and C3 was the most frequent immunoreactant (82.7%). Any kind of extracutaneous involvement was present in 47 (58%) of patients, with renal involvement being the most frequent (53.1%), followed by articular (18.5%) and gastrointestinal (11.1%) involvement. The presence of renal disease was associated with the detection of IgG in the lesional skin (p = 0.017), and with the absence of IgM in the lesional skin (p = 0.032). There was a significant association between C3 deposition and joint involvement (p = 0.05). Study limitations This is a single-center study with a retrospective design. Conclusion DIF seems to be a useful ancillary diagnostic tool in the evaluation of cutaneous vasculitis, but the relationship between DIF findings and systemic involvement needs to be further elucidated due to contradictory data in the current literature.

Particularidades dos Pacientes com Arterite de Takayasu em Idade Mais Avançada: Estudo Coorte, Retrospectivo e Transversal / Characteristics of Older Patients with Takayasu's Arteritis: A Two-Center, Cross-Sectional, Retrospective Cohort Study

Resumo Fundamentos Poucos estudos avaliaram pacientes idosos com Arterite de Takayasu (AT). Objetivo Avaliar o progresso de AT em diferentes grupos etários em seus possíveis efeitos sobre o tratamento medicamentoso e atividade da doença. Métodos este estudo transversal, retrospectivo, do tipo coorte incluiu 66 pacientes com AT. Os pacientes foram entrevistados, e dados dos 12 meses anteriores foram coletados dos prontuários médicos eletrônicos. Os pacientes foram divididos em quatro quartis de acordo com idade atual, e comparados quanto aos dados clínicos e laboratoriais, tratamento, comorbidades, status da doença, e status funcional. Um p<0,05 foi estabelecido como estatisticamente significativo. Resultados Os grupos foram definidos como Q1(22-36 anos, n=16), Q2(37-42 anos, n=18), Q3(43-49 anos, n=17), e Q4(51-66 anos, n=15). A frequência de pacientes com atividade da doença, fadiga, comorbidades e comprometimentos vasculares, e o índice de extensão da doença (DEI. Tak) foram comparáveis entre os grupos. Pacientes com idade mais avançada apresentaram maior duração da doença (p=0,001) e maior comprometimento do status funcional (Q2 versus Q3, p=0,003); menos pacientes usaram prednisona (Q1:43,8%; Q2:33,3%; Q3:11,8%; e Q4:6,7%; p=0,049) e agentes imunossupressores [Q1:100,0%; Q2:66,7%; Q3:58,8% e Q4:46,7%; Q1 versus Q3 (p=0,043) e Q1 versus Q4 (p=0,005) nas análises post-hoc]. Além disso, os níveis de danos da doença, sintomas de uma nova ocorrência de AT, e complicações nos 12 meses precedentes não foram diferentes entre os grupos. Conclusão Pacientes com AT e idade mais avançada requerem mínima intervenção medicamentosa e apresentam maior comprometimento no status funcional, o que pode ser atribuído a fatores relacionados ao envelhecimento.

Abstract Background Few studies have assessed elderly patients with Takayasu's arteritis (TAK). Objectives To evaluate the progression of TAK in different age groups and its possible effects on drug treatment and disease activity. Methods This cross-sectional and retrospective cohort study included 66 TAK patients. Patients were interviewed and data of the 12 preceding months were collected from electronic medical records. The patients were divided into four quartiles according to current age and compared for clinical and laboratory data, treatment, comorbidities, disease status, and functional status. Statistical significance was set at p<0.05. Results The groups were Q1(22-36 years, n=16), Q2(37-42 years, n=18), Q3(43-49 years, n=17), and Q4(51-66 years, n=15). The frequency of patients with disease activity, fatigue, comorbidities and vascular impairments, and the TAK disease extent index were also comparable between the groups. With age, disease duration was longer (p=0.001), fewer patients used prednisone (Q1:43.8%, Q2:33.3%, Q3:11.8%, and Q4:6.7%; p=0.049) and immunosuppressive drugs [Q1:100.0%, Q2:66.7%, Q3:58.8%, and Q4:46.7%; Q1 versus Q3 (p=0.043), and Q1 versus Q4 (p=0.005) in post-hoc analyses], and patients had greater functional status impairment (Q2 versus Q3, p=0.003). In addition, the levels of disease damage, new TAK symptoms, and complications in the preceding 12 months were not different between the groups. Conclusions Older patients with TAK require minimal drug treatment, and have greater impairment of functional status, which may be attributed to aging-related factors.

Vasculitis crioglobulinémica por hiperviscosidad y formación de criogel como debut de mieloma múltiple. Caso clínico / Cryoglobulinemic vasculitis due to hyperviscosity and cryogel formation as the onset of multiple myeloma. Report of one case

Multiple Myeloma (MM) is characterized by a clonal expansion of plasma cells in the bone marrow. These cells typically produce a monoclonal immunoglobulin, and its symptoms arise either from plasma cell infiltration in several organs, or secondary to the presence of a monoclonal protein peak. Symptoms can be summarized by the acronym CRAB (hypercalcemia, renal failure, anemia and bone lesions). Sometimes, in the setting of a protein secreting monoclonal gammopathy, formation of cryoglobulins develops. Cryoglobulins are plasma proteins that precipitate at low temperatures, forming a cold - induced precipitate at small vessels, causing a wide range of clinical manifestations. We report a female consulting for ulcers lasting 2 months in the left foot associated with purpuric lesions in both lower limbs. Protein electrophoresis showed a monoclonal peak in the gamma region. Bone marrow aspirate showed 27% of plasma cells with kappa chain restriction by cytometry. The presence of cryoglobulins was confirmed. The patient was treated with dexamethasone and bortezomib, with a progressive healing of lower limb lesions and disappearance of cryoglobulins. She was discharged in good conditions.

Arteritis de células gigantes: ¿Cómo debutan pacientes chilenos? Análisis de casos y revisión de la literatura / Giant cell arteritis. Experience in 32 patients

BACKGROUND: Giant cell Arteritis (GCA) is the most common systemic vasculitis in patients over 50 years. Diagnosis is based on clinical, laboratory, imaging and biopsy. Temporal artery biopsy (TAB) may be inconclusive in up to 40% of patients. AIM: To describe disease features of patients diagnosed with GCA. MATERIAL AND METHODS: Review of pathology reports of giant cell arteritis and clinical records of patients seen with the diagnosis between 2000 and 2019. Demographic, clinical, laboratory, histopathology, imaging, treatment and follow-up variables were analyzed. RESULTS: We fetched 32 patients with a median age at diagnosis of 70.5 years (range 57-90), 81% women. Twenty eight percent had polymyalgia. 72% had only cranial symptoms, 12% had extracranial involvement and 13% exclusive extracranial involvement. The median time from onset of symptoms to diagnosis was two months (range 0.5-8). All had elevated erythrocyte sedimentation rate and c reactive protein. A TAB was performed in 27 patients and in 17 (65.4%) it confirmed the diagnosis. Transmural inflam- mation was the most frequent finding. All patients received steroids. Follow-up information was available from 25 patients and 92% received a steroid-spa- ring agent, usually methotrexate (74%). Ninety two percent achieved clinical remission in the first year and 59% had minor relapses during steroid tapering. CONCLUSIONS: Our patients showed frequent extracranial involvement and TAB was a useful diagnostic tool.

Peripheral ulcerative keratitis as presenting manifestation of systemic microscopic polyangiitis: a case report / Ceratite ulcerativa periférica como manifestação de poliangiíte microscópica sistêmica: relato de caso

ABSTRACT Microscopic polyangiitis is a rare autoimmune disease of unknown etiology, characterized by inflammation and necrosis of blood vessels. It forms a part of the antineutrophil cytoplasmic antibody-associated vasculitides-a heterogeneous group of disorders characterized by vasculitis. It is a systemic disease affecting multiple organs. The patients may present with a wide variety of symptoms. Ocular manifestations may present as its initial clinical symptoms, necessitating a multidisciplinary approach for reducing the morbidity and mortality. Early diagnosis aids in the formulation of appropriate treatment and prevention of further complications. Aggressive treatment, including surgery, is often necessary to limit structural damage and preserve visual function. We present the case of an 82-year-old woman who initially presented with peripheral ulcerative keratitis that led to the diagnosis of microscopic polyangiitis.

RESUMO A poliangeíte microscópica é uma doença autoimune rara de etiologia desconhecida, caracterizada por inflamação e necrose dos vasos sanguíneos. Faz parte das vasculites associadas a anticorpos citoplasmáticos antineutrófilos - um grupo heterogêneo de doenças caracterizadas por vasculite. É uma doença sistêmica que afeta vários órgãos. Os pacientes podem apresentar uma grande variedade de sintomas. As manifestações oculares podem apresentar-se como seus sintomas clínicos iniciais, necessitando de abordagem multidisciplinar para redução da morbimortalidade. O diagnóstico precoce ajuda na formulação do tratamento adequado e na prevenção de complicações futuras. O tratamento agressivo, incluindo cirurgia, muitas vezes é necessário para limitar o dano estrutural e preservar a função visual. Apresentamos o caso de uma mulher de 82 anos que inicialmente apresentou ceratite ulcerativa periférica que levou ao diagnóstico de poliangite microscópica.

Constitutional symptoms and anemia as the initial manifestation of vasculitis in an older adult. case report

ABSTRACT Introduction: Vasculitis comprises a group of often serious diseases that have an unspecific onset and a late diagnosis. The following report describes a case of vasculitis that may lead to considering this disorder as a differential diagnosis from the beginning of the care process to ensure a comprehensive approach and early treatment initiation that reduce associated morbidity and mortality and improve the success rate of treatments. Case presentation: A 77-year-old female, with a 2-year history of arterial hypertension was admitted to the emergency department of a secondary care center for having experienced symptoms of asthenia, fever, hyporexia and weight loss for a month. The patient was hospitalized for further testing and, given the findings, a possible bacterial translocation secondary to intestinal neoplasm was suspected. Empirical antibiotic treatment was started, but her condition continued to worsen. Complementary tests were performed, although they were not conclusive. Due to the persistence of fever, kidney failure and anemia, a kidney biopsy was performed, revealing arterial vessel with fibrinoid necrosis and associated polymorphonuclear infiltrates, clear signs of an active vasculitis of the microscopic polyangiitis type. Several lines of treatment were used, but the patient evolved unfavorably and died. Conclusions: The presentation of this unusual case intends to contribute to the early diagnosis of this disorder by making medical staff aware of the possibility of considering it when symptoms suggest other diseases, or even when nonspecific symptoms such as anemia and weight loss occur.

RESUMEN Introducción. Las vasculitis son enfermedades graves que suelen tener un debut muy inespecífico y un diagnóstico tardío, lo que implica una alta tasa de fracaso terapéutico. Se presenta un caso de vasculitis que puede contribuir a considerar esta enfermedad como parte del diagnóstico diferencial desde las primeras etapas del proceso de atención para garantizar un abordaje integral y un inicio temprano del tratamiento, lo que reduciría la morbimortalidad asociada a estas entidades y mejoraría la tasa de éxito de los tratamientos. Presentación del caso. Mujer caucásica de 77 años que como único antecedente presentaba hipertensión arterial de dos años de evolución y quien consultó al servicio de urgencias de una institución de segundo nivel por cuadro clínico de un mes de evolución consistente en astenia, febrícula, hiporexia y pérdida de peso. La paciente fue hospitalizada para completar la historia clínica y dados los hallazgos se sospechó de una posible translocación bacteriana secundaria a una neoplasia intestinal y se inició cobertura antibiótica empírica, pero su condición seguía empeorando. Se realizaron pruebas complementarias que no arrojaron resultados concluyentes; ante la persistencia de la fiebre, la insuficiencia renal y la anemia, se realizó una biopsia de riñón que mostró vaso arterial con necrosis fibrinoide e infiltrados de polimorfonucleares asociados, claros signos de una vasculitis activa del tipo poliangeítis microscópica. Se instauró el tratamiento indicado pero la paciente tuvo una evolución desfavorable y falleció. Conclusiones. La exposición de este caso inusual contribuye a que los profesionales de la salud consideren el diagnóstico de vasculitis desde el inicio de la atención, aun cuando la sintomatologia sugiere otras patologías o incluso cuando se presentan síntomas tan inespecíficos como anemia y pérdida de peso, ya que esto ayudará a establecer un diagnóstico temprano.

Clinical characteristics and prognostic factors in an argentinian cohort with ANCA-associated vasculitis / Características clínicas y factores pronósticos en una cohorte argentina de vasculitis asociada a ANCA

Abstract ANCA-associated vasculitis is a heterogeneous group of rare autoimmune conditions of unknown cause. Clinical characteristics and prognostic factors were analyzed in 47 patients: 20 (42.5%) with granulomatosis with polyangiitis, 17 (36.2%) with microscopic polyangiitis, 6 (12.8%) with renal-limited vasculitis, and 4 (8.5%) with eosinophilic granulomatosis with polyangiitis. Mean age at diagnosis was 53.5 ± 16.5 years and the median of BVAS (Birmingham Vasculitis Activity Score) was 14 (4-42). The most frequent clinical manifesta tions were: general in 44 (93.6%), renal in 30 (63.8%) and respiratory in 28 (59.6%). All received corticosteroids at the beginning of treatment. Intravenous cyclophosphamide was associated in 20 (42.5%) and oral route in 14 (29.8%); azathioprine in 3 (6.4%) and rituximab in 2 (4.2%). At a median follow-up of 35.5 months (range 0.14- 234), 21 relapses were recorded in 14 patients. Overall mortality was 3.5 deaths per 100 patient-year in the whole group. Those over 55 years old, the presence of alveolar hemorrhage, those with FFS (Five Factor Score) of 2, and patients with MPA had poor prognosis. Renal involvement, ANCA pattern and BVAS were not associated to a poorer prognosis.

Resumen Las vasculitis asociadas a ANCA son un grupo heterogéneo de entidades autoinmunes, poco frecuentes, de etiología desconocida. Analizamos las características clínicas y factores pronóstico en 47 pacientes: 20 (42.5%) granulomatosis con poliangeítis, 17 (36.2%) poliangeítis microscópica, 6 (12.8%) vasculitis limitada al riñón y 4 (8.5%) granulomatosis eosinofílica con poliangeítis. La edad promedio al diagnóstico fue 53.5 ± 16.5 años y la mediana de BVAS (Birmingham Vasculitis Activity Score) 14 (4-42). Las manifestaciones clínicas más frecuentes fueron: generales en 44 (93.6%), renales 30 (63.8%) y respiratorias en 28 (59.6%). Todos recibieron corticoides al inicio del tratamiento. Se asoció ciclofosfamida endovenosa en 20 (42.5%) y oral en 14 (29.8%); azatioprina en 3 (6.4%) y rituximab en 2 (4.2%). En una mediana de seguimiento de 35.5 meses (rango 0.14-234), se registraron 21 recaídas en 14 pacientes. La mortalidad fue 3.5 por cien pacientes-año en todo el grupo. Los mayores de 55 años, con presencia de hemorragia alveolar, FFS (Five Factor Score) de 2, y los casos con poliangeítis microscópica tuvieron peor pronóstico. El compromiso renal, el patrón de ANCA y el BVAS no se asociaron a peor pronóstico.

Acometimento vascular na doença de Behçet: o processo imunopatológico / Vascular involvement in Behçet's disease: the immunopathological process

Resumo A doença de Behçet constitui uma forma rara de vasculite sistêmica, que acomete de pequenos a grandes vasos. É caracterizada por manifestações mucocutâneas, pulmonares, cardiovasculares, gastrointestinais e neurológicas. Sua apresentação clínica é bastante ampla, variando de casos mais brandos a casos graves, com acometimento multissistêmico, caracteristicamente com exacerbações e remissões. Suas causas ainda são desconhecidas; entretanto, há evidências genéticas, ambientais e imunológicas, como a associação com o alelo HLA-B51. Todas essas, em conjunto, apontam para um processo imunopatológico anormal, com ativação de células da imunidade inata e adaptativa, como as células natural killer, neutrófilos e células T, que geram padrões de respostas e citocinas específicos capazes de gerar mediadores que podem lesionar e inflamar o sistema vascular, resultando em oclusões venosas, arteriais e/ou formação de aneurismas.

Abstract Behçet's disease is a rare form of systemic vasculitis that affects small to large vessels. It is characterized by mucocutaneous, pulmonary, cardiovascular, gastrointestinal, and neurological manifestations. Its clinical presentation is quite wide, ranging from milder cases to severe cases, with multisystemic involvement, characteristically with exacerbations and remissions. Its etiopathogenesis is still unclear, although there is evidence of genetic, environmental, and immunological factors, such as the association with the HLA-B51 allele. In conjunction, all of these point to an abnormal immunopathological process, with activation of cells of innate and adaptive immunity, such as NK cells, neutrophils, and T cells, which generate specific response patterns and cytokines capable of generating mediators that can damage and inflame blood vessels, resulting in venous and arterial occlusions and/or aneurysm formation.

Case series of patients with cholesterol crystal embolism syndrome that mimics systemic vasculitis / 中华风湿病学杂志

Objective:To improve the awareness of cholesterol crystal embolism syndrome (CCE) inrheumatologists.Methods:The clinical characteristics of 40 Chinese CCE patients admitted to our department (one case) were summarize and in the literature (thirty-nine cases) were reviewed.Results:Among these 40 patients, 87.5%(35/40) were male and the mean age was (68±6) years. All patients suffered from athero-sclerosis and 87.5%(35/40) of them had precipitating factors such as endovascular intervention, vascular surgery, anticoagulant, or thrombolytic therapy. The clinical manifestations included renal insufficiency (90.0%, 36/40), blue toe syndrome (82.5%, 33/40), ulceration or gangrene (25.0%, 10/40), and livedo reticularis (15%, 6/40). Acute phase reactant was tested in 25 cases, of whom 84.0%(21/25) showed elevated C-reactive protein (CRP) and 56.0%(14/25) showed elevated erythrocyte sedimentation rate (ESR).Conclusion:Rheumatologists should be alert that CCE is one of the differential diagnosis of systemic vasculitis, especially for patients with severe atherosclerosis.

Enfermedad de Behcet: un reto diagnóstico en reumatología. Descripción de una serie de casos y revisión de la literatura / Behcet's disease: a diagnostic challenge in rheumatology. Description of a case series and a review of the literature

RESUMEN La enfermedad de Behcet es una entidad clínica autoinflamatoria, de etiología desconocida, generalmente con compromiso sistémico, con un patrón de exacerbación y remisión frecuente que se asocia a retraso en el diagnóstico. El diagnóstico de esta enfermedad es complejo, por esta razón presentamos 4 casos de pacientes con enfermedad de Behcet, que durante el abordaje clínico fueron consideradas otras enfermedades de naturaleza autoinmune. La revisión integrada de la historia clínica, la aparición de úlceras orales y genitales, así como el estudio de tipificación del complejo mayor de histocompatibilidad (HLA) permitieron diagnosticar la enfermedad de Behcet.

ABSTRACT Behcet disease is a rare autoinflammatory disorder of unknown aetiology and is characterised by systemic manifestations with an exacerbation-remission pattern, often associated with diagnostic delay. The diagnostic approach to this disease is complex. A report is given on four cases of patients fulfilling the diagnostic criteria for Behcet disease. Other autoimmune rheumatic diseases were considered in the clinical approach. A meticulous clinical evaluation, taking into consideration relapsing aphthous ulcers in oral mucosa and genitalia, and HLA typing allowed a proper diagnosis of Behcet disease to be made.

Update on vasculitis: overview and relevant dermatological aspects for the clinical and histopathological diagnosis - Part II

Abstract Vasculitis is a group of several clinical conditions in which the main histopathological finding is fibrinoid necrosis in the walls of blood vessels. This article assesses the main dermatological aspects relevant to the clinical and laboratory diagnosis of small- and medium-vessel cutaneous and systemic vasculitis syndromes. The most important aspects of treatment are also discussed.

Update on vasculitis: an overview and dermatological clues for clinical and histopathological diagnosis - part I

Abstract The term vasculitis refers to the inflammation of vessel walls. It may range in severity from a self-limited disorder in one single organ to a life-threatening disease due to multiple organ failure. It has many causes, although they result in only a few histological patterns of vascular inflammation. Vessels of any type and in any organ can be affected, a fact that results in a broad variety of signs and symptoms. Different vasculitides with indistinguishable clinical presentations have quite different prognosis and treatments. This condition presents many challenges to physicians in terms of classification, diagnosis, appropriate laboratory workup, and treatment. Moreover, it compels a careful follow-up. This article reviews the Chapel-Hill 2012 classification, etiology, recent insights in pathophysiology, some important dermatological clues for the diagnosis and summarizes treatment of some of these complex vasculitis syndromes.

Vasculitis with a neuromuscular presentation and associated cancer revealed by autopsy

Peripheral neuropathy is common, but rarely due to vasculitis. This report is the case of a 74-year-old woman with systemic vasculitis who presented with progressive arm and leg weakness associated with numbness. Autopsy revealed a colon cancer, which may have triggered the vasculitis. This case illustrates the association between vasculitis and malignancy. The best treatment of vasculitis in patients with cancer-associated vasculitis is usually treatment of the cancer, which often yields remission of the vasculitis. This case also illustrates the difficulty of suspecting vasculitis since the symptoms and signs are nonspecific and protean. It is important not to miss a diagnosis of vasculitis. It is often life-threatening. It is treatable. The critical step in the diagnosis of vasculitis is to think of it.

Granulomatosis de Wegener mimetizando una lesión tumoral de vértice de pulmón. Reporte de un caso clínico y revisión de la literatura / Wegener's granulomatosis mimicking a tumor of the lung vertex. Report of a clinical case and review of the literature

La granulomatosis con poliangeítis antes denominada con el epónimo de granulomatosis de Wegener, clasifica entre las vasculitis sistémicas, de causa desconocida, que afecta a los vasos de pequeño y mediano calibre. Se caracteriza por la afectación del aparato respiratorio en su tracto superior, pulmones, así como a los riñones, aunque puede afectar a otros órganos y sistemas del organismo humano. Los anticuerpos anti citoplasma de neutrófilos son positivos con una frecuencia que alcanza el 80 por ciento de casos, y la característica histológica más relevante es la presencia de lesiones granulomatosas necrosantes. El diagnóstico se basa en las manifestaciones clínicas, la biopsia con estudio histológico de los tejidos y órganos afectados así como la presencia de anticuerpos anti citoplasma de neutrófilos. Hoy en día se agrupa dentro de las denominadas vasculitis asociadas a anticuerpos anti citoplasma de neutrófilos positivas. Nuestro estudio tuvo como objetivo presentar un caso clínico inusual, en el cual reportamos a una paciente de 55 años de edad la cual fue atendida por presentar manifestaciones clínicas, de laboratorio y radiológicas que permiten confirmar el diagnóstico de una Granulomatosis de Wegener. Su forma clínica de expresión inicial mostró. una serie de signos y síntomas constitucionales como fiebre superior de 38 grados de varios días de evolución en horario vespertino, astenia, pérdida de apetito, artromialgias, manifestaciones respiratorias como dolor torácico e intercostal izquierdo, tos con expectoración mucosa, y disnea a esfuerzos físicos en aumento. Al examen físico se recogieron datos positivos como palidez cutánea mucosa, la presencia de disminución del murmullo vesicular a nivel del vértice del pulmón izquierdo con estertores crepitantes y una imagen a modo de masa tumoral redondeada del lóbulo superior del pulmón que orientaba al diagnóstico de una neoplasia de vértice de pulmón. Se realizaron múltiples estudios considerando el proteiforme cuadro clínico, los estudios inmunológicos realizados, y la histología por biopsia pulmonar, los que demostraron la existencia de lesiones de tipo granulomatosas compatibles con G. Wegener. Resultó efectiva la respuesta terapéutica con drogas esteroideas e inmunosupresoras en forma de bolos de ciclofosfamida acompañados de un fuerte tratamiento antibiótico de amplio espectro. Concluimos que se trata de un raro caso de granulomatosis de Wegener cuya forma de debut hizo plantear el diagnóstico inicial de una lesión tumoral de vértice de pulmón. No conocemos de otro caso similar reportado en nuestro medio(AU)

Granulomatosis with polyangiitis, formerly known as Wegener's Granulomatosis, is classified as systemic vasculitis, of unknown cause, affecting small and medium-sized vessels. It is characterized by the involvement of the respiratory system in its upper tract, lungs, as well as the kidneys, although it can affect other organs and systems. Neutrophil anticithoplasma antibodies are positive with a frequency that reaches over 80 percent of cases, and the most relevant histological feature is the presence of necrotizing granulomatous lesions. The diagnosis is based on clinical manifestations, biopsy with histological study of the affected tissues and organs as well as the presence of Neutrophil anticithoplasma antibodies. Nowadays it is grouped into the so-called Neutrophil anticithoplasma antibodies positive vasculitis. Arthromyalgia, respiratory manifestations such as thoracic and left intercostal pain, cough with mucous expectoration, and dyspnea on physical efforts in increase. The physical examination collected positive data such as mucous skin pallor, the presence of decreased vesicular murmur at the level of the left vertex of the lung with crackling rales and an image as a rounded tumor mass of the upper lobe of the lung that guided the diagnosis of a vertex neoplasm of lung. Multiple studies were carried out considering the proteiform clinical picture, the immunological studies performed, and the lung biopsy histology, which demonstrated the existence of granulomatous lesions compatible with G. Wegener. The therapeutic response was effective with steroidal and immunosuppressive drugs in the form of cyclophosphamide boluses accompanied by a strong broad-spectrum antibiotic treatment. We conclude that this is a rare case of Wegener's granulomatosis, whose debut form raised the initial diagnosis of a tumor of the lung vertex. We do not know of another similar case reported in our country(AU)

Granulomatosis de Wegener, una afección poco frecuente / Wegener's granulomatosis, a rare condition

Introducción: la granulomatosis de Wegener es una vasculitis sistémica, poco frecuente, cuyo sustrato etiopatogénico es la inflamación de los vasos sanguíneos impidiendo la libre circulación del flujo sanguíneo. Clinicamente se caracteriza por presencia de manifestaciones respiratorias, nasales, auditivas y renales; frecuentemente se asocian trastornos infecciosos y alérgicos. Objetivo: socializar los principales elementos etiopatogénicos, manifestaciones clínicas y exámenes complementarios que permiten definir el granulomatosis de Wegener. Caso clínico: se presenta el caso de una paciente de 32 años de edad la cual es referida desde la atención primaria de salud, por presentar manifestaciones clínicas y de laboratorio que permiten confirmar el diagnóstico de una granulomatosis de Wegener. Conclusiones: la granulomatosis de Wegener es una rara enfermedad que, aunque se presenta fundamentalmente en pacientes femeninas entre 40 y 50 años, puede presentarse en pacientes de cualquier edad sin distinguir preferencia por el sexo. Sus principales manifestaciones clínicas son la toma respiratoria y renal acompañada de manifestaciones generales. El uso de esteroides constituye la piedra angular del tratamiento, al cual se adicionan medicamentos para el control de la enfermedad como es el caso del methotrexate.

Introduction: Wegener's granulomatosis is a rare systemic vasculitis, whose etiopathogenic substrate is the inflammation of the blood vessels, preventing the free circulation of blood flow. Clinically it is characterized by the presence of respiratory, nasal, auditory and renal manifestations; Infectious and allergic disorders are frequently associated. Objective: to socialize the main etiopathogenic elements, clinical manifestations and complementary examinations that allow us to define Wegener's granulomatosis. Clinical case: the case of a 32-year-old female patient is reported from primary health care, due to clinical and laboratory manifestations that confirm the diagnosis of Wegener's granulomatosis. Conclusions: Wegener's granulomatosis is a rare disease that, although it occurs mainly in female patients between 40 and 50 years, can occur in patients of any age without distinguishing preference for sex. Its main clinical manifestations are respiratory and renal uptake accompanied by general manifestations.
