ABSTRACT

La membrana de oxigenación extracorpórea arteriovenosa se utiliza cuando ocurre falla hemodinámica y respiratoria refractaria al tratamiento convencional; brinda soporte hemodinamico transitorio, oxigenacion y remocion de CO2, y permite reposo pulmonar. Asimismo ofrece la posibilidad de realizar ventilación ultraprotectiva y evitar la generación de VILI (Ventilation-Induced Lung Injury). No ha sido demostrada su utilización como una terapia frecuente en los casos con insuficiencia hemodinámica secundaria a shock obstructivo por afectación mediastínica. Presentamos el caso de un paciente con shock obstructivo por una masa mediastínica de origen linfoproliferativo tratada con membrana de circulación arteriovenosa extracorpórea.


The arteriovenous extracorporeal membrane is used in patients with hemodynamic and respiratory failure, unresponsive to conventional treatment. It provides transitory hemodynamic support, oxygenation and removal of CO2, allowing pulmonary rest. Moreover it offers the possibility of ultraprotective ventilation and avoids generation of VILI (Ventilation-Induced Lung Injury). It is not frequently used in patients with hemodynamic failure secondary to obstructive shock due to mediastinal compromise. We present the case of a patient with obstructive shock, mediastinal mass of lymphoproliferative origin that was treated with extracorporeal arteriovenous circulation membrane.

ABSTRACT

SUMMARY We describe the case of a female patient, 52 years old, with dizziness and left motor incoordination for 2 weeks. Brain MRI magnetic resonance imaging) revealed a hyperintense lesion on T2-weighted images, without restricted diffusion, in the left middle cerebellar peduncle. Spectroscopy demonstrated peak of lipids and perfusion did not show any elevation in relative cerebral blood volume (rCBV). The patient underwent an open biopsy and resection, and the diagnosis of diffuse large B-cell lymphoma (DLBCL) was established. The patient received intravenous dexamethasone with symptoms remission, followed by four cycles of methotrexate plus cytarabine. After 3 months, the patient returned with decreased consciences level and a new MRI revealed a right superior frontal gyrus lesion with features suggesting a lymphomatous lesion. The patient died five days after her relapse.


RESUMO Descrevemos o caso de uma paciente do sexo feminino, de 52 anos, apresentando história de tontura e perda da coordenação motora do lado esquerdo há duas semanas. A RM (ressonância magnética) de crânio revelou uma lesão hiperintensa nas imagens ponderadas em T2, sem restrição à difusão, localizada no pedúnculo cerebelar médio esquerdo. A espectroscopia demonstrou pico de lipídeos, sem elevação do volume sanguíneo cerebral relativo (rCBV) à perfusão. A paciente foi submetida à biópsia a céu aberto, estabelecendo o diagnóstico de linfoma difuso de grandes células B (DLBCL). Houve remissão dos sintomas após o início do tratamento com dexametasona endovenosa, seguida de quatro ciclos de metotrexato associado à citarabina. Após três meses, a paciente retornou apresentando rebaixamento do nível de consciência, e a RM de crânio revelou uma nova lesão de origem linfomatosa no giro frontal superior direito. A paciente faleceu após cinco dias.

ABSTRACT

El linfoma difuso de células B grandes (LDCBG) es el linfoma más frecuente. La presentación clínica puede ser nodal o extranodal y sus síntomas dependen de la localización tumoral; en la mayoría de los casos están asociados a algún tipo de inmunodeficiencia. Referiremos un caso de LDCBG de presentación atípica en una localización muy infrecuente. Es importante tener en cuenta estas situaciones, ya que pueden simular otros procesos patológicos, retrasando así su correcto diagnóstico y por lo tanto un adecuado tratamiento. (AU)


Diffuse large cell lymphoma B (LDCBG) is the most common type of lymphoma. It´s clinical presentation can be nodal or extranodal and it's symptoms depend where the tumor is located and whether is associated or not with an immunodeficiency disease. We present an atypical presentation of a LDCBG in a very unusual location. It´s important to consider these kind of appearance, as they can mimic other oral pathological processes, delaying their correct diagnosis and therefore an appropriate treatment. (AU)

ABSTRACT

Primary colorectal lymphoma is a rare form of presentation of gastrointestinal tract lymphomas. Inflammatory bowel disease and its treatment are risk factors for its development. We report a 47-year-old male patient with Ulcerative Colitis of two years of evolution, treated initially with azathioprine and later on with infliximab. Due to a relapse in symptoms after the second dose of infliximab, a new coloncoscopy was performed showing a rectal ulcerative lesion, corresponding to a large cell Non-Hodgkin's Lymphoma. The patient was successfully treated with RCHOP chemotherapy (Rituximab cyclophosphamide doxorubicin vincristine prednisone). He is currently in disease remission.

ABSTRACT

El linfoma no Hodgkin primario de la glándula suprarrenal es una patología muy poco común. Su diagnóstico inicial es difícil siendo este histológico. El linfoma B difuso de células grandes es el tipo histológico más frecuente. Se presenta el caso mujer de 62 años a la que se le realiza tomografía axial computarizada abdominal que muestra una masa de 18 cms dependiente de la glándula suprarrenal y con características de carcinoma. Se realiza exéresis de la tumoración, siendo la anatomía patológica linfoma difuso de célula grande B. Este tipo de linfoma tiene mal pronóstico describiéndose supervivencias medias en torno a los 13 meses. No existe un régimen terapéutico bien definido; aunque el tratamiento más aceptado es el esquema R-CHOP. El papel de la radioterapia y de la exéresis tumoral no está claramente establecido. El linfoma suprarrenal primario debe tenerse en cuenta en el diagnóstico diferencial de pacientes que presentan una masa suprarrenal. Ante la sospecha de esta patología es preferible realizar una biopsia con aguja guiada por prueba de imagen para evitar una intervención quirúrgica innecesaria(AU)


Primary non- Hodgkin`s lymphoma of the adrenal gland is very rare. Its initial diagnosis is difficult and needs to be histological. Diffuse large B- cell lymphoma is the most common histological type. This is the report of a 62 years old woman, who was performed abdominal tomography to disclose a 18 cm tumor in the adrenal gland with carcinoma characteristics. The tumor was removed and the final pathologic diagnosis was diffuse large B-cell lymphoma. This type of lymphoma has poor prognosis since the average survival rates are roughly 13 months. There is no well-defined therapeutic regimen, although the most widely accepted treatment is R-CHOP scheme. The roles of radiotherapy and tumor resection are not clearly established. Primary adrenal lymphoma should be considered in the differential diagnosis of patients presenting with an adrenal mass. When this condition is suspected, then it is advisable to perform a imaging-guided needle biopsy to avoid unnecessary surgery(AU)

ABSTRACT

Primary orbital lymphoma is an extremely rare entity; most of the reported cases being MALT lymphoma. Herein we report a case of extranodal primary diffuse large B cell lymphoma in a 17 years old boy who presented with proptosis. The patient responded well to chemotherapy; presently he is in remission with no residual disease.

ABSTRACT

Pulmonary parenchymal involvement and mediastinal lymphadenopathy are less common manifestations of non-Hodgkin's lymphoma as compared to Hodgkin's lymphoma. The pattern of pulmonary disease varies with histological type of non-Hodgkin's lymphoma. We are presenting an uncommon case of diffuse histiocytic lymphoma having miliary mottling who responded well to chemotherapy.
