Sindrome de Blesovsky. A propósito de un caso / Anatomical and clinical implications of the humeral torsion

Introducción: La atelectasia redonda de pulmón, conocida como síndrome de Blesovsky, constituye un pseudotumor pulmonar de ubicación periférica asociado a la exposición al asbesto y al engrosamiento pleural. Los hallazgos imagenológicos pueden establecer el diagnóstico,pero no puede descartarse algún proceso neoplásico maligno. La precisión en el diagnóstico puede dificultarse por causas como la progresión radiológica y empeoramiento clínico del paciente. Objetivo: Presentación de caso clínico y revisión bibliográfica. Caso clínico: Paciente de 76 años, masculino, que consulta por síndrome de impregnación, pérdida de peso y anemia de 2 meses de evolución. Estudios imagenológicos muestran imagen nodular de 20 mm en lóbulo inferior derecho. Exploración videotoracoscópica: engrosamiento pleural de aspecto benigno (fibrosis) sin palparse nódulo pulmonar. TAC control a los 3 meses: aumento de la imagen nodular (30 mm) Se decide reexploración y resección pulmonar. Pieza de patología: Atelectasia redonda. Discusión: La atelectasia redonda es una entidad benigna, que como tal tiende a ser estable y en algunos casos evoluciona a la resolución espontanea. Aunque la seguridad diagnóstica mediante la Tac es alta, no existe un patrón individual que permita diferenciarla de un proceso maligno. Precisa de un seguimiento clínico estrecho y de la realización de pruebas diagnósticas invasivas si persisten las dudas y/o se detecta un crecimiento de la lesión. Se acepta como conducta diagnóstica y/o terapéutica la resección pulmonar lobar o sublobar.

Introduction: Rounded atelectasis lung, known as Blesovsky syndrome, is a pulmonary pseudotumor of peripheral location associated with asbestos exposure and pleural thickening. Image findings may establish the diagnosis but a malignant neoplastic process can not be ruled out. The accuracy of the diagnosis canbe difficult for reasons such as radiological progression and clinical worsening of the patient.Objective: Clinical case presentation and literature review.Case Report: 76 years old male patient, who consults forimpregnation syndrome, weight loss and anemia 2 months ofevolution. Imaging studies show 20 mm nodular image in the rightlower lobe. Laparoscopic exploration: pleural thickening withbenign aspect (fibrosis) without palpable image. CT 3 monthslater: Increased nodular image (30 mm) It decides relaparoscopyand pulmonary resection. Piece lobectomy: rounded atelectasis.Discusion: Rounded atelectasis is a benign entity, and as suchtends to be stable and in some cases resolve spontaneously.Although security diagnosed by tomography is high, there is nosingle pattern that allows to differentiate from malignancy.Requires close clinical monitoring and invasive diagnostic tests ifdoubts persist and/or injury growth is detected. Lobar or sublobarlung resection is accepted as diagnostic and therapeutic conduct.

Pseudocyst in pulmonary acute respiratory distress syndrome (ARDS).

Childhood ARDS is mostly caused by pneumonia. Pulmonary pseudocysts are reported in adults recovering from ARDS, usually in non-dependent lung regions. The authors present a 1.5-year-old boy, who survived severe pulmonary ARDS with development of pulmonary giant pseudocysts and other structural abnormalities in dependent lung region. To the best of authors knowledge, it is the first follow up report of pulmonary abnormality in a toddler with ARDS of extreme severity.

Pseudotumor pulmonar como apresentação inicial de granulomatose de Wegener / Lung pseudotumor as the initial presentation of Wegener's granulomatosis

A granulomatose de Wegener é uma doença inflamatória multissistêmica de etiologia desconhecida, que se caracteriza por vasculite de pequeno e médio calibre. As manifestações clínicas mais comuns envolvem o trato respiratório superior, pulmões e rins e as alterações encontradas nos exames de imagem são geralmente opacidades pulmonares ou nódulos múltiplos, bilaterais e, em 50 por cento dos casos, cavitações. O tratamento é feito com corticoides e imunossupressores. Descreve-se um caso atípico de um homem de 61 anos cuja investigação inicial de um tumor pulmonar unilateral evidenciou, na verdade, Granulomatose de Wegener.

Wegener's granulomatosis is a multisystemic inflammatory illness of unknown etiology, characterized by vasculitis of small and medium caliber vessels. The most common clinical manifestations involve the upper respiratory tract, lungs and kidneys. Common alterations in imaging studies include pulmonary opacities and bilateral multiple nodules, cavitations occurring in 50 percent of the cases. Treatment includes corticosteroids and immunosuppressants. We describe an atypical case of a 61-year-old man initially investigated due to suspicion of a unilateral lung tumor, which proved to be, in fact, a case of Wegener's granulomatosis.

Pseudotumor inflamatório endobrônquico: relato de caso / Endobronchial inflammatory pseudotumor: a case report

O pseudotumor inflamatório de pulmão é uma neoplasia benigna rara que geralmente se manifesta como um nódulo pulmonar solitário. A apresentação endobrônquica é infreqüente. O tratamento de escolha continua sendo a cirurgia conservadora e deve-se sempre procurar obter margens livres devido à possibilidade de recidiva local. Esse artigo relata o caso de um paciente de 36 anos, com crises de sibilância e tosse, que foi submetido, com sucesso, à broncoplastia para ressecção de um pseudotumor inflamatório endobrônquico.

Inflammatory pseudotumor of the lung is a rare form of benign neoplasia and is generally characterized by a solitary pulmonary nodule. The endobronchial presentation is uncommon. Conservative surgery remains the treatment of choice, and surgeons should always strive to achieve tumor-free margins due to the possibility of local recidivism. This article reports the case of a 36-year-old male patient with recurrent attacks of wheezing and cough. The patient underwent successful bronchoplasty for the resection of an endobronchial inflammatory pseudotumor.

Plasma cell granuloma of lung.

A 10 years old girl presented with fever, cough, haemoptysis, dyspnoea on exertion of two months duration. Chest skiagram and CT-scan of thorax revealed well defined mass lesion of varying density occupying right upper and middle lobes with areas of calcification. On thoracotomy, a huge mass in the right upper lobe was resected and hispathological examination proved it to be a case of plasma cell granuloma.

Pseudotunor inflamatorio de pulmón: en preescolar femenina: a propósito de un caso / Inflammatory pseudotumors of the lung: in female preschool: a purpose of a case

El pseudotumor inflamatorio es una lesión benigna inflamatoria caracterizada en el aspecto histológico por una mezcla de fibroblastos, histiocitos, linfocitos y células plasmáticas. Relativamente rara, con localización tamaño, y sintomatología variable, que puede simular la presencia de un tumor maligno. En la infancia se presenta como una masa intrapulmonar. Se describe caso de paciente preescolar femenina de 3 años de edad, quien consultó a nuestro centro por presentar fiebre, disfagia y tos de 3 meses de evolución. Se evidenció en estudios imaginológicos de tórax, imagen densa en base de hemitórax izquierdo que impresionó como empiema tabicado. Se le realizó toracotomía izquierda evidenciándose tumoración intercisural, adherida fuertemente a pared torácica, diafragma y proyectada a mediastino posterior. Además lesiones satélites en pleura parietal. Se toma muestra de lesión principal y resección de las satélites para estudio histopatológico, la cual reportó pseudotumor inflamatorio. El pseudotumor inflamatorio es una patología tumoral benigna, que se sospecha en niños con infecciones respiratorias a repetición, refractaria a tratamiento convencional y con hallazgos imaginológicos compatibles con lesión ocupante de espacio a nivel pulmonar. Se puede observar su relación con el virus de Epstein-Baar. El diagnóstico es sólo posible por biopsia, y el tratamiento de elección es resección quirúrgica. Sin embargo, en este caso se evidenció aparente mejoría dada por la disminución de la masa tumoral con el tratamiento con antiinflamatorios no esteroideos.

The pseudo inflammatory tumor is a benign lesion characterized in the histological aspect by a mixture of fibroblasts, histiocytes, lymphocytes and plasmatic cells. Relatively rare, with location, size and variable simptomatology that it can simulate the presence of a malignant tumor. In the childhood it appears like an intrapulmonary mass. A case of female infant patient of 3 years old is described, that consult to our center to display fever, dysphagia and cough of 3 months of evolution. In radiological images of thorax were viewed a dense image in the left thorax base that impresses septate emphyema. A left thoracotomy was made viewed an intercysural tumor like, adhered strongly to thoracic wall, diaphragm and projected to later mediastinum, and in addition, satellites injuries in parietal pleural. An incisional sample of main lesion was taking and complete resection of the satellites to histopathology study, which reported pseudo inflammatory tumor. Pseudo inflammatory tumor is a benign tumoral pathology that is suspected in children with repetition respiratory infection refracted to conventional treatment and with image findings compatible with tumor at pulmonary level. Its relation with the virus of Epstein-Baar can be observed. The diagnosis is only possible by biopsy, and the election treatment is the surgical resection. Although in this case the improvement was viewed by diminution of tumor mass with use of non steroidal anti inflammatory drugs.

Pseudotumor inflamatório do pulmão / Inflammatory pseudotumor of the lung

O pseudotumor inflamatório de pulmão é uma afecção rara, e representa um dilema pela semelhança com processo maligno nos aspectos radiológicos, macroscópicos e patológicos. Relata-se o caso de um paciente com queixas respiratórias, que após propedêutica adequada foi submetido à toracotomia exploradora, com diagnóstico de pseudotumor confirmado pela imunohistoquímica. São discutidos dados referentes à história clínica, aspectos radiológicos, histopatológicos e cirúrgicos, além de formas de tratamento da condição.

A Case of Pulmonary Inflammatory Pseudotumor: Recurrence Appearing as Several Consolidative Lesions after Complete Resection

Inflammatory pseudotumor (plasma cell granuloma) of the lung is an uncommon nonneoplastic tumor of unknown origin. This tumor typically manifests as a solitary, peripheral, and sharply circumscribed mass. Multiple lesions are seen in about 5% of cases. Resection is recommended for both diagnosis and treatment, and this tumor does not generally recur after complete resection. Here, we report a case of recurrent inflammatory pseudotumor after complete resection; the recurrence was detected as a series of bilateral consolidated lesions with an internal air bronchogram. This is an unusual finding with regard to inflammatory pseudotumors.

Pulmonary Inflammatory Pseudotumor: A report of 28 cases

BACKGROUND: Pulmonary inflammatory pseudotumor is an uncommon benign lesion of the lung. In Korea, most literature of the pulmonary inflammatory pseudotumor was case reports. METHODS: We collected 28 cases of pulmonary inflammatory pseudotumor in Korea. This collective series included 4 cases from our hospital and 24 cases were reviewed from the literature since 1977. The analysis involved the age, sex, chief complaint, hematologic examination, size and location of the lesion, cavity formation, presence of calcification and treatment method. RESULTS: Male was more prevalent (81.5%) than female and mean age was 37.9 years old (6~63 yrs). Chief complaints were cough (44.4%), chest pain (29.6%), fever (22.2%), hemoptysis (15%), sputum (15%) and dyspnea (11.1%). There were asymptomatic cases in 11.1%. Hematologic examination revealed normal finding (53.3%) and anemia (20%). The mean size of the lesion was 4.76 cm (1.5~14 cm) and the locations were parenchymal (85.7%), endobronchial (10.7%) and endotracheal (3.6%). Except the endotracheal case, the lesions were in the right (46.4%), the left (42.8%) and bilateral (7.1%). Calcifications (18.5%) and cavitations (11.1%) were present. Diagnostic methods were open thoracotomy (82.1%), bronchoscopy (3.6%), needle aspiration biopsy (7.1%) and core needle gun biopsy (7.1%). Treatments were surgery (85.2%), steroid therapy (7.4%), rigid bronchoscopic removal (3.7%) and observation (3.7%). Postoperative recurrence occurred in only 1 case (4.3%). CONCLUSION: Pulmonary inflammatory pseudotumor was more prevalent in the male, and patients presented with the respiratory symptoms were common. It was necessary to do surgery in most cases for diagnosis and/or treatment.

Pseudotumor inflamatório em criança pré-escolar / Inflammatory pseudotumor in childhood

Descreve-se o caso de um menino de cinco anos, no qual, durante o controle de tratamento de pneumonia adquirida na comunidade, foi evidenciada uma massa circunscrita, heterogênea, no lobo superior esquerdo. Foi realizada lobectomia superior esquerda, com diagnóstico histológico pós-operatório de pseudotumor inflamatório histiocítico. Não se detectou recorrência nos quatro anos de pós-operatório. De etiologia ignorada, essas lesões podem ter comportamento local semelhante ao de sarcomas, razões que fazem da exérese com amplas margens cirúrgicas o método de eleição para diagnóstico e tratamento simultâneos

Pseudotumor fibroso calcificado del mediastino. Reporte de un caso de una nueva entidad que involucra al mediastino / Calcified fibrous pseudotumor of the middle mediastinum

Recientemente, se describió una nueva entidad de apariencia tumoral en los tejidos blandos (extremidades, tronco, escroto, nunca y axila) así como en la pleura, que se denomina seudotumor fibroso pleura, que se denomina seudotumor fibroso calcificado. No conocemos reportes previos en el mediastino. El caso que informamos es de un hombre de 44 años de edad que acudió al Hospital por dolor torácico y opacidad hiliar izquierda en la radiografía de tórax. La tomografía computarizada, muestra un tumor en el mediastino medio, de 7.6 X 6.1 cm de diámetro mayor con 1380 UH en las zonas de calcificación. Asienta arriba del cayado de la arteria pulmonar y bronquio principal izquierdo. Histopatológicamente está circunscrita, encapsulada y compuesta de tejido fibroso hialinizado, con infiltrado linfoplasmocitario, calcificaciones sammomatosas y distróficas, es menester distinguirlo del tumor fibroso de la pleura, del granuloma hializado y del seudotumor inflamatorio. Su tratamiento es la resección y no conocemos hasta el momento reportes de recidiva

Granuloma hialinizante pulmonar: presentación de dos casos

El Granuloma Hialinizante Pulmonar (GHP), es una entidad relativamente nueva descrita hace poco más de una década. Su incidencia real se desconoce, pero aún así, se considera una patología poco usual, cuya etiología se ignora, aún cuando se describe asociada a entidades como fibrosis mediastinal, retroperitoneal, o a procesos infecciosos como la tuberculosis, debiendo ser diferenciada de lesiones metastásicas y otras entidades pulmonares menos frecuentes. En este artículo registramos dos casos de GHP, los cuales fueron diagnosticados en el Hospital Santa Clara de Bogotá, complementándolo con una revisión de la literatura existente.
