Granuloma no caseificante como primera manifestación de artritis reumatoide. A propósito de un caso / Noncaseating granuloma as first manifestation of rheumatoid arthritis: a case report

RESUMEN Los nódulos reumatoides se han descrito en cerca del 30% de los pacientes con artritis reumatoide, se localizan generalmente a nivel subcutáneo, pero son poco frecuentes en órganos viscerales; generalmente aparecen en estados tardíos de la enfermedad. Su apariencia puede ser confundida con otras condiciones clínicas en las localizaciones atípicas. Presentamos el caso de una paciente que comenzó con nódulos reumatoides en el hígado como primera manifestación de artritis reumatoide.

ABSTRACT The rheumatoid nodules have been described in 30% of patients with rheumatoid arthritis. There are localized generally at subcutaneous planes, are rare in visceral organs, and appear tipically in advance stages of the disease. Its appearance in atyipical localizations can be confused with other conditions. We are going to discuss a patient who debuted with rheumatoid nodules in the liver as first manifestation of rheumatoid arthritis.

Nódulo reumatoide benigno en sóleo. Reporte de un caso / Benign rheumatoid nodule in the soleus muscle. Case report

RESUMEN Los nódulos reumatoides benignos son nódulos subcutáneos, idénticos en su morfología e histología a los que ocurren en el transcurso de la artritis reumatoide (AR), que aparecen en personas sin síntomas de artritis y con factor reumatoide (FR) negativo. Se presenta el caso de un varón de 46 arios de raza caucasiana que consultó por tumoración en la pierna derecha. Destacaba negatividad de factor reumatoide, anticuerpos anti péptido citrulinado, anticuerpos antinucleares y anticuerpos anticitoplasma de neutrófilo, así como normalidad de los reactantes de fase aguda. Una ecografía musculoesquelética mostró una tumoración sólida de 3,5 x 1,5 cm, de márgenes bien definidos, en músculo sóleo, con una estructura heterogénea hipoecoica con vascularización intra y perilesional. La resonancia magnética evidenció una tumoración de carácter fibroso sin datos sugestivos de agresividad. Una biopsia guiada por ecografía mostró histología característica de nódulo reumatoide. Se discuten la clínica, el diagnóstico, el diagnóstico diferencial y el tratamiento de los nódulos reumatoides benignos.

ABSTRACT Benign rheumatoid nodules are subcutaneous nodules, identical in morphology and histo logy to those that occur in the course of rheumatoid arthritis. They appear in people without symptoms of arthritis and with negative rheumatoid factor. The case is presented of a 46-year-old Caucasian man who consulted for a tumour inthe right leg. He was negative for rheumatoid factor, anti-citrullinated protein antibodies, antinuclear antibodies, and antineutrophil cytoplasmic antibodies, as well as for acute phase reactants. A musculoskeletal ultrasound showed a solid tumour of 3.5 × 1.5 cm with well-defined margins in the soleus muscle, and with a heterogeneous hypoechoic structure with intra- and peri-lesional vascularisation. The magnetic resonance imaging showed a fibrous tumour with no signs suggestive of aggressive growth. An ultrasound-guided biopsy sho wed the characteristic histology of the rheumatoid nodule. The clinical picture, diagnosis, differential diagnosis, and treatment of benign rheumatoid nodules are discussed.

Case for diagnosis. Subcutaneous nodules in the plantar region

Abstract The authors report a case of mobile and painful nodules on the bilateral plantar surface of a female patient referred by the rheumatology service, where she was being followed-up for rheumatoid arthritis. A nodule excision was performed for differential diagnosis and symptom relief; the histopathological analysis was compatible with a rheumatoid nodule. Although rheumatoid nodules are a common manifestation of rheumatoid arthritis, exclusive plantar involvement is seldom described in the literature.

Rare Form of Rheumatoid Nodule around Ischial Tuberosity Mimicking Ischiogluteal Bursitis

We are reporting about a case of a rheumatoid nodule, beneath the ischial tuberosity, mimicking ischiogluteal bursitis. Rheumatoid nodules are frequently seen, at the subcutaneous soft tissues of repetitive mechanical irritation points, and prominent bones. There have been no reported cases of rheumatoid nodules, extending just beneath the ischial tuberosity bone. A 68-year-old woman with a seven-year history of rheumatoid arthritis, suffered for six months, from right buttock swelling and discomfort in seating. A cystic lesion postero-inferior to the ischial tuberosity, was noted in the MRI scan, which was thought to be ischiogluteal bursitis, because of its characteristic location and appearance. Histopathologic analysis and gross findings on the operation, revealed no evidence of bursitis.

Formation of multiple pulmonary nodules during treatment with leflunomide / Formação de múltiplos nódulos pulmonares durante tratamento com leflunomida

Pulmonary involvement is one of the extra-articular manifestations of rheumatoid arthritis and can be due to the disease itself or secondary to the medications used in order to treat it. We report the case of a 60-year-old woman who had been diagnosed with rheumatoid arthritis and developed multiple pulmonary nodules during treatment with leflunomide.

O comprometimento pulmonar é uma das manifestações extra-articulares da artrite reumatóide e pode ser devido à própria doença ou secundário às medicações utilizadas para seu tratamento. Este trabalho relata um caso de uma paciente de 60 anos de idade com diagnóstico de artrite reumatoide que evoluiu com múltiplos nódulos pulmonares durante o tratamento com leflunomida.

Azathioprine-induced accelerated cutaneous and pulmonary nodulosis in a patient with rheumatoid arthritis

We report the case of a 42-year-old female with a 5-year history of rheumatoid arthritis treated with Rituximab and Azathioprine. Three months after the initiation of Azathioprine, the patient started with dry cough and noted the rapid development of multiple subcutaneous nodules on her right leg. CT scan of the chest demonstrates pulmonary nodulosis. Skin biopsy was compatible with rheumatoid nodule. A diagnosis of "accelerated cutaneous and pulmonary nodulosis" was considered. Azathioprine was discontinued and Rituximab was restarted. Two months later, most of the subcutaneous nodules had disappeared. This is the second case report of accelerated rheumatoid nodulosis in association with Azathioprine treatment.

Rheumatoid Nodulosis with Recurrent Nodules: A Case Report / 대한내과학회지

Rheumatoid nodulosis, a benign variant of rheumatoid arthritis (RA), is a rare condition characterized by multiple subcutaneous nodules and positive rheumatoid factor in the absence of systemic manifestations or joint disease. Asymptomatic nodules rarely require treatment, and are unlikely to recur after excision, except in cases in which RA develops. Here, we describe an unusual case of recurrent rheumatoid nodulosis in a 42-year-old female presenting with recurrent subcutaneous nodules on the plantar side of her left foot, which caused pain when walking. Nodules were initially excised to control symptoms; however, since the excision, the nodules have recurred twice in the absence of other RA symptoms.

Reticulohistiocitosis multicéntrica en paciente con artritis reumatoidea / Multicentric reticulohistiocytosis in a patient with rheumatoid arthritis

La reticulohistiocitosis multicéntrica (RHM) es una patología sistémica, de baja prevalencia, considerada dentro delgrupo de las histiocitosis no Langerhans. Clínicamente se caracteriza por el compromiso de la piel y las articulaciones.Se describe el caso de un paciente masculino con antecedente de diagnóstico de artritis reumatoidea (AR) de 10 años de evolución, que en 2008 se presenta a la consulta por un cuadro de poliartritis asociado a prurito cutáneo,hiperpigmentación facial y presencia de múltiples lesiones nodulares rojovioláceas en codos y manos. Mediante biopsia de las lesiones cutáneas se confirma el diagnóstico de RHM. Cabe destacar que se ha descripto hasta un 30% de asociación de la entidad con patologías neoplásicas; en nuestro paciente el tamizaje fue negativo. En cuanto al tratamiento no existen protocolos avalados científicamente dada la baja incidencia de la enfermedad, por lo que sigue siendo experimental. En nuestro paciente se realizó tratamiento exitoso con metotrexate.

Multicentric reticulohistiocytosis (MRH) is a systemic pathology of low prevalence within the group of histiocytosis no-Langerhans. It is clinically characterized by the involvement of skin and joints. The present article describes the case of a male subject with a diagnosis of rheumatoid arthritis of 10 years’ duration. In 2008 he was seen in our service with multiple nodular, red skin lesions in his hands and elbows. A biopsy of the cutaneous lesions confirmed the diagnosis of MRH. An association with neoplasic disease has been described in 30% of the cases; however, in our patient cancer screening was negative. With regard to the treatment, scientifically proven protocols do not exist. This is due to the low incidence of the disease. Our patient responded well to methotrexate.

Antígenos HLA de clase ii en pacientes con artritis reumatoide ecuatorianos y asociación con el factor reumatoide, anticuerpos anti-citrulinados y nódulos reumatoides / HLA antigens class ii in patients with ecuadorian rheumatoid arthritis and association with the rheumatoid factor, anti-citrulinated antibodies and rheumatoid nodules

Objetivo Determinar los antígenos de Clase II en 52 pacientes con artritis reumatoide (AR) y 52 controles, y establecer la asociación de los antígenos de Clase II DRB1* con el factor reumatoide (FR), anticuerpos anti-péptido cíclico citrulinados (anti-CCP) y nódulos reumatoides. Material y Métodos Estudio de casos y controles, realizado en pacientes del Hospital Vicente Corral Moscoso y José Carrasco Arteaga de la ciudad de Cuenca-Ecuador; se incluyeron 52 pacientes con AR que cumplen los criterios del Colegio Americano de Reumatología (ACR) y 52 controles. Se identificaron a través de la Reacción en Cadena de la Polimerasa (PCR), los diferentes tipos de HLA que tienen cada uno de los 52 pacientes con AR y controles. Se buscó asociación de los HLA-DR1* con la AR y las pruebas de laboratorio: FR, anticuerpos anti-CCP y con nódulos reumatoides. El análisis estadístico se realizó con el cálculo de OR (IC 95%) y 2 de Pearson con corrección de Fisher y la información se procesó en SPSS v15. Resultados Los alelos más frecuentes fueron HLA-DRB1*09 (17,3%) OR 3,42 (IC95% 1,21 ­ 10,14) y HLADRB1*04 (32,7%) OR 1,81 (IC95% 0,93 ­ 3,55). Tanto el factor reumatoide como los anticuerpos anti-péptido cíclico citrulinados estuvieron presentes en el 82,7% de pacientes con artritis reumatoide y los nódulos reumatoides se detectaron en el 19,2% de pacientes con AR. Se encontró asociación entre los nódulos reumatoides con valores altos de FR y anti-CCP y estos a su vez con los alelos HLA-DRB1*14 y HLADRB1*04. La mayoría de pacientes con alelos HLA-DRB1*09 con predominio heterocigoto tuvieron anticuerpos anti-CCP y FR positivo. Conclusión La presencia de los alelos HLA-DRB1*04 y HLADRB1*09 está relacionada con la susceptibilidad de presentar AR en pacientes ecuatorianos, además se relaciona con valores elevados de factor reumatoide y anticuerpos anti-péptido cíclico citrulinados.

Objective To determine Class II antigens in 52 patients with rheumatoid arthritis (RA) and 52 controls and establish the association of Class II antigens DRB1* with rheumatoid anti- cyclic citrullinated peptide (anti-CCP) rheumatoid factor (RF), and antibodies rheumatoid nodules. Methods and Materials Case and control study in patients from the Hospital Vicente Corral Moscoso and José Carrasco Arteaga of Cuenca-Ecuador; 52 patients with rheumatoid arthritis who satisfy the criteria of ACR-American College of Rheumatology and 52 healthy patients. The different types of HLA from each 52 patients with rheumatoid arthritis and controls were identified through PCR - Polymerase Chain Reaction. Association of HLA-DR1* with rheumatoid arthritis and rheumatoid factor, anti-citrullinated and rheumatoid nodules. The statistical analysis was done by the OR (IC 95%) and 2 of Pearson with Fisher correction and the information was processed in SPSS v15. Results The most frequency alleles were HLA-DRB1*09 (17,3%) OR 3,42 (IC95% 1,21 ­ 10,14) and HLADRB1*04 (32,7%) OR 1,81 (IC95% 0,93 ­ 3,55). The rheumatoid factor and anti-cyclic citrullinated peptide antibodies were presented in 82,7% of patients with rheumatoid arthritis and rheumatoid nodules was detected in the 19.2% of patients with rheumatoid arthritis . An association between rheumatoid nodules with high values of rheumatoid factor and anti-ccp and these in turn with HLA-DRB1*14 y HLA-DRB1*04 alleles were found. The majority of patients with HLA-DRB1*09 alleles with heterozygote predomination had positive anti-ccp and rheumatoid factor. Conclusion The presence of HLA-DRB1*04 and HLA-DRB1*09 alleles is related with the susceptibility of present rheumatoid arthritis in Ecuadorian patients, and it is related with higher values of rheumatoid factor and anti-cyclic citrullinated peptide.

Pulmonary Cryptococcosis That Mimicked Rheumatoid Nodule in Rheumatoid Arthritis Lesion / 결핵및호흡기질환

Recently, the incidence of pulmonary cryptococcosis is gradually increasing in rheumatoid arthritis (RA) patients. Pulmonary rheumatoid nodules (PRN) are rare manifestations of RA. Eighteen months ago, a 65-year old woman was admitted to hospital due to multiple nodules (2.5x2.1x2 cm) with cavitations in the right lower lobe. She was diagnosed with RA three year ago. She had been taking methotrexate, leflunomide, and triamcinolone. A video-assisted thoracoscopic surgery biopsy was performed and PRN was diagnosed. However, a newly growing huge opacity with cavitation was detected in the same site. Pulmonary cryptococcal infection was diagnosed through a transthoracic computed tomograpy guided needle biopsy. Cryptococcus antigen was detected in serum but not in cerebrospinal fluid. The patient was treated with oral fluconazole which resulted clinical improvement and regression of the nodule on a series of radiography. Herein, we report the case of pulmonary cryptococcosis occurring in the same location as that of the PRN.

Nódulos reumatoides: avaliação comparativa da resposta terapêutica com triancinolona e fluoruracil intralesional / Rheumatoid nodules: evaluation of the therapeutic response to intralesional fluorouracil and triamcinolone

Os nódulos reumatoides correspondem à manifestação extra-articular mais comum da artrite reumatoide, ocorrendo em cerca de 20-25 por cento dos pacientes. A etiologia é desconhecida. Apesar de os nódulos poderem apresentar remissão espontânea durante o tratamento, eles, em geral, representam um desafio terapêutico. Apresenta-se um caso no qual se avaliou a resposta dos nódulos reumatoides por meio de ultrassonografia após infiltração de triancinolona e 5-fluoruracil.

Rheumatoid nodules are the most common extra-articular manifestation of rheumatoid arthritis and are present in around 20-25 percent of patients. Their etiology is unknown and although the nodules may undergo spontaneous remission during the treatment of rheumatoid arthritis, they usually constitute a therapeutic challenge. The present paper describes a case in which the response of rheumatoid nodules was evaluated by ultrasound following infiltration of triamcinolone acetonide and 5-fluorouracil.

Pneumoconiose reumatoide (síndrome de Caplan) com apresentação clássica / Rheumatoid pneumoconiosis (Caplan's syndrome) with a classical presentation

Apesar de rara, a pneumoconiose reumatoide, também chamada de síndrome de Caplan, pode ser diagnosticada entre trabalhadores expostos à sílica e entre pacientes com silicose, pneumoconiose dos mineiros de carvão e asbestose. A maior prevalência ocorre entre os silicóticos, apesar de ter sido descrita inicialmente em mineiros de carvão com pneumoconiose. O achado que define o tipo clássico da síndrome é a presença de nódulos reumatoides nos pulmões, independente da presença ou não de pequenas opacidades pneumoconióticas, ou de grandes opacidades de fibrose pulmonar maciça, associada ou não a um quadro de artrite reumatoide em atividade. Relatamos o caso de uma mulher com quadro de artrite reumatoide, diagnosticada 34 anos após exposição à sílica livre em uma indústria de porcelana por 7 anos, apresentando radiograma de tórax com opacidades arredondadas de 1 a 5 cm de diâmetro, distribuídas na periferia de ambos os pulmões. A biópsia transtorácica guiada por TC de um dos nódulos revelou tratar-se de nódulo reumatoide com macrófagos em paliçada, típico da síndrome de Caplan. São discutidos aspectos de diagnóstico da síndrome, classificação e ocorrência, ressaltando a importância da anamnese ocupacional em casos de artrite reumatoide com opacidades radiológicas pulmonares.

Although rare, rheumatoid pneumoconiosis, also known as Caplan's syndrome, can occur in workers exposed to silica, as well as in patients with silicosis, coal workers' pneumoconiosis or asbestosis. Prevalence is higher among patients with silicosis, despite the fact that it was originally described in coal workers with pneumoconiosis. The classical finding that defines this syndrome is that of rheumatoid nodules in the lungs, regardless of whether there are small rounded opacities suggestive of pneumoconiosis or large opacities consistent with massive pulmonary fibrosis, with or without clinical rheumatoid arthritis. We describe the case of a female patient with rheumatoid arthritis, diagnosed 34 years after 7 years of occupational exposure to silica at a porcelain plant. A chest X-ray showed circular opacities of 1-5 cm in diameter, bilaterally distributed at the periphery of the lungs. A CT-guided thoracic punch biopsy of one of those nodules revealed that it was rheumatoid nodule surrounded by a palisade of macrophages, which is typical of Caplan's syndrome. Aspects of diagnosis, classification and occurrence of this syndrome are discussed, emphasizing the importance of the occupational anamnesis of patients with rheumatoid arthritis and lung opacities on chest X-rays.

Aspergillus colonisation of pulmonary rheumatoid nodules: a rare cause of 'bull's eye' appearance.

Pulmonary rheumatoid nodules [PRNs] are a well described manifestation of rheumatoid arthritis [RA]. Fungal colonisation of these nodules is a rare phenomenon. We report a case of Aspergillus colonisation of multiple cavitary rheumatoid nodules in a young female patient with long-standing seropositive RA with 'bull's eye' appearance on computed tomography [CT]. The 'bull's eye' appearance inside PRNs should raise the suspicion of possible fungal colonisation. In patients with RA, a high index of suspicion for the fungal colonisation should be considered by the clinicians treating pulmonary cavitary nodules.

Pattern of young and elderly onset rheumatoid arthritis among a group of Egyptian patients

Rheumatoid arthritis [RA] differs depending on the age of disease onset. The differences between young onset rheumatoid arthritis [YORA] and elderly onset rheumatoid arthritis [EORA] are important because they have clinical and therapeutic implications. The study was conducted on 1185 patients who were ranked after classification according to age at onset of the disease into YORA I, 16-40 years, YORA II, 41-60 years and EORA >60 years. All were compared, based on disease duration [DD], disease activity, severity parameters and drug history. YORA I comprised 298 patients, 28.85% males, age 29.4 +/- 6 and DD 4 +/- 3.3 y, YORA II included 539 patients, 33.77% males, age 49.7 +/- 6.1 y. and DD 6.5 +/- 5.6 y. EORA included 348 RA patients 40.5% males, age 67.1 +/- 6.6 y, DD 9.95 +/- 7.2 y. Activity was increased in EORA compared to YORA I and YORA II, while severity decreased in EORA. ESR, CRP and degree of anemia were higher in EORA. RF titer was higher in YORA. In YORA peripheral joints of the hands and feet were more involved while, large joints in EORA. Rheumatoid nodules were increased in YORA I than EORA p= 0.04. Polymyalgia rheumatica was exclusively present in EORA group 25 patients 7.2%. YORA used methotrexate and its mean dose was higher than EORA. EORA on multiple DMARD 57.9% or biologics 0.8% was significantly lower compared with YORA 186.3% and 1.7%, p= 0.001. EORA has more active and less disabling and affects more males than YORA. The use of biologic therapy and combination DMARD therapy was less in EORA

Nodulosis pulmonar reumatoidea resistente a etanercep / Resistant rheumatoid lung Nodulosis etanercep

La nodulosis reumatoidea es una manifestacion extra-articular de la artritis reumatoidea (AR). El 20-30 por ciento de los pacientes con aR presentan nodulos, mas a menudo de localizacion subcutanea. La prevalencia de nodulos pulmonares es del 1 porciento o 22 porciento segun se evalue al paciente con radiografia o tomografia axial computada (TAC) de alta resolucion. Se desconoce cual es el mejor tratamiento de la nodulosis reumatoidea. Si bien la eficacia de los antagonistas del factor de necrosis tumoral alfa, sobre los sintomas articulares en pacientes con AR ha sido bien demostrada en diversos estudios clinicos y en la practica asistencial, la repuesta de la nodulosis reumatoidea frente a estos compuestos ha sido evaluada. Por otro lado, cuando la nodulosis reumatoidea pulmonar aparece o se cavita en un paciente tratado con meicamentos biologicos dirigido contra el factor de necrosis tumural alfa, es necesarios descartar diagnosticos diferenciales tales como infecciones oportunistas y cences.

Reticulohistiocytose multicentrique : a propos de deux observations

Introduction :La Reticulohistiocytose Multicentrique (RHM) est une affection peu decrite dans la litterature. Nous rapportons deux observations de RHM faites a Dakar; caracteristiques par l'agressivite des lesions et la presentation cutanee pure dans un cas.Observations : La premiere observation concernait une patiente agee de 34 ans admise pour des papulo nodules dissemines; une polyarthrite bilaterale asymetrique destructrice n'epargnant pas les inter-phalangiennes distales et un epanchement sero-hematique aux genoux. La deuxieme observation etait faite chez une patiente agee de 26 ans qui avait des papulo-nodules dissemines depuis 10 ans. L'examen histologique en faveur de la RHM dans les deux cas; montrait une infiltration intradermique d'histiocytes multinucleees sans plasmocytes ni polynucleaires ni cellules xanthomisees. La corticotherapie etait decevante dans la premiere observation. La surveillance etait indiquee dans le deuxieme cas. Conlusion : La RHM est une maladie rare chronique handicapante a localisation tegumentaire diffuse isolee exceptionnelle en Afrique
