Inflammatory myofibroblastic tumor of the lung: case series

Inflammatory myofibroblastic tumor is a rare occurrence in general practice. Its biologic nature, natural history and response to different treatment modalities are obscure. We retrospectively reviewed clinical and pathological features of 5 patients with inflammatory myofibroblastic tumor of the lung observed between 1999 and 2006. Under-study patients were 3 women and 2 men with a median age of 32.6 years. All patients were symptomatic. Computed tomography [CT] scan demonstrated a mass in all cases. Four patients underwent surgery [tumor resection in 1, lobectomy in 1, bilobectomy in 1 and lobectomy with mediastinal mass debulking also in 1]. Complete resection was achieved in 2 patients who are currently alive with no evidence of disease. One died due to progressive disease. Another is alive with disease after incomplete resection, and one refused any kind of surgery. There was no operative mortality. All patients were under follow-up [range, 5 to 60 months; median 39 months]. This study illustrates that some inflammatory myofibroblastic tumors behave aggressively and have a poor prognosis. It also confirms that radical resection is the treatment of choice for this malignancy

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.

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

Endobronchial inflammatory pseudotumor of the lung

Inflammatory pseudotumor [also called plasma cell granuloma, histiocytoma and x-anthofibroma] is a benign, slow growing lesion which may present with cough, dyspnea, hemoptysis and unresolving pneumonia or can be discovered radiographically as a localised lesion. It has been reported in individuals up to 70 years old, but approximately two-thirds have developed in individuals under 30 years of age. The sex incidence is approximately equal. Inflammatory pseudotumors of the lung are usually peripheral lesions but may occasionally be endobronchial. We report the case of an endobronchial inflammatory pseudotumor in a 17-year-old girl who presented with unresolving right-sided pneumonia. Appropriate radiological, bronchoscopic and histopathological investigations lead to accurate pre-operative diagnosis and early complete surgical resection through a limited right main bronchus incision [bronchotomy]. The patient made good postoperative recovery and an excellent prognosis is anticipated

Pseudotumor inflamatorio del pulmón en la infancia / Lung inflammatory pseudotumor in childhood

Introducción. El pseudotumor inflamatorio del pulmón es una lesión no neoplásica que puede simular un proceso maligno y que explica más de la mitad de los casos de masas pulmonares en la infancia. Existen escasas publicaciones de esta enfermedad en la edad pediátrica. Casos clínicos. Se describen 2 pacientes con pseudotumor inflamatorio del pulmón tratados quirúrgicamente, haciendo énfasis en los hallazgos clínicos, radiológicos e histopatológicos.Conclusión. Debe sospecharse esta enfermedad ante la presencia de masa intrapulmonar en la radiografía de tórax con antecedente de proceso infeccioso. El diagnóstico es forzosamente histopatológico y el tratamiento siempre es quirúrgico. Lesión intrapulmonar; pseudotumor inflamatorio; granuloma de células plasmáticas.

Pseudotumor inflamatório do pulmäo / Granuloma plasma cell pulmonary

Os pseudotumores inflamatórios do pulmäo säo raros. Caracterizam-se pela presença de massas pulmonares benignas, de etiologia desconhecida, compostas por uma variedade de células mesenquimais e inflamatórias. Radiologicamente assemelham-se aos carcinomas do pulmäo. Os autores relatam dois casos de pseudotumor inflamatório do pulmäo tratados no Instituto Nacional do Câncer e fazem breve revisäo do tema.
