ABSTRACT

OBJETIVO: Catalogar alterações encontradas em imagens obtidas por fibrobroncoscopia em pacientes com diagnóstico de neoplasia pulmonar e correlacionar esses achados com achados histopatológicos. MÉTODOS: Estudo retrospectivo envolvendo 212 pacientes com diagnóstico de câncer de pulmão confirmado por citologia obtida por lavado broncoalveolar e/ou histopatologia de biópsia endobrônquica ou transbrônquica. Os dados foram obtidos no Serviço de Endoscopia Respiratória do Hospital São Salvador (Goiânia-GO), entre 2005 e 2010. Os achados endoscópicos foram classificados como tumor endoscopicamente visível, tumor endoscopicamente não visível e lesão na mucosa, assim com quanto à pr sença/tipo de secreção. Os tumores visíveis também foram classificados de acordo com sua localização na árvore traqueobrônquica. RESULTADOS: O principal achado endoscópico foi a presença de massa endobrônquica (64%), seguido por infiltração da mucosa (35%). Quanto aos tipos histológicos (n = 199), os mais prevalentes foram carcinoma escamoso (39%), adenocarcinoma (21%), carcinoma de pequenas células (12%) e carcinoma de grandes células (1%). Mais de 45% dos tumores visíveis estavam localizados nos brônquios superiores. O carcinoma escamoso (n = 78) apresentou-se mais frequentemente como massa tumoral endobrônquica (74%), infiltração da mucosa (36%), estreitamento do lúmen (10%) e compressão extrínseca (6%). CONCLUSÕES: Nossos resultados indicam que a massa tumoral endobrônquica é o achado endoscópico que mais sugere malignidade. Proporcionalmente, infiltração da mucosa é mais comumente achada em carcinoma de pequenas células. Estreitamento do lúmen, compressão extrínseca, lesão na mucosa e secreção endobrônquica prevalecem no adenocarcinoma.


OBJECTIVE: To compile fiberoptic bronchoscopy findings in patients diagnosed with lung cancer and to correlate those with histopathological findings. METHODS: This was a retrospective study involving 212 patients with a confirmed diagnosis of lung cancer by cytological evaluation of BAL specimens or by histopathological evaluation of endobronchial or transbronchial biopsy specimens. The data were collected at the Respiratory Endoscopy Sector of Hospital São Salvador, located in the city of Goiânia, Brazil, between 2005 and 2010. The endoscopic findings were classified as endoscopically visible tumor, endoscopically invisible tumor, mucosal injury, as well as being classified by the presence/type of secretion. The visible tumors were also classified according to their location in the tracheobronchial tree. RESULTS: Endobronchial mass (64%) and mucosal infiltration (35%) were the main endoscopic findings. The histological type was determined in 199 cases, the most prevalent types being squamous carcinoma, in 78 (39%), adenocarcinoma, in 42 (21%) small cell carcinoma, in 24 (12%), and large cell carcinoma, in 2 (1%). More than 45% of the visible tumors were at the upper bronchi. Squamous carcinoma (n = 78) was most commonly visualized as an endobronchial mass (in 74%), mucosal infiltration (in 36%), luminal narrowing (in 10%), or external compression (in 6%). CONCLUSIONS: Our results show that the endobronchial mass is the most common bronchoscopic finding that is suggestive of malignancy. Proportionally, mucosal infiltration is the most common finding in small cell carcinoma. In adenocarcinoma, luminal narrowing, external compression, mucosal injury, and endobronchial secretion prevail.

ABSTRACT

A pneumonia lipoide é uma doença pouco diagnosticada, causada pela aspiração de partículas oleosas para dentro dos pulmões. Os casos relatados têm sido relacionados ao uso de óleo mineral como laxativo, mas outras soluções oleosas também podem causar a doença. Relatamos o caso de uma paciente de 50 anos com queixa de tosse produtiva, sendo diagnosticada inicialmente com hiper-reatividade brônquica e doença do refluxo gastroesofágico (DRGE). A paciente foi submetida a tratamento para DRGE. Devido à persistência da tosse, a paciente foi submetida a TC de tórax, fibrobroncoscopia e biópsia pulmonar a céu aberto, sendo diagnosticada com pneumonia lipoide. A paciente foi questionada quanto ao uso de substâncias oleosas, relatando o uso crônico de óleo de prímula. Com a suspensão do uso da substância e a continuidade do tratamento para DRGE, houve melhora do quadro.


Lipoid pneumonia is an underdiagnosed disease that is caused by the aspiration of lipid particles into the lungs. Although most of the reported cases have been associated with the use of mineral oil as a laxative, other lipid substances can also cause the disease. We report the case of a 50-year-old female patient with a complaint of productive cough who was initially diagnosed with bronchial hyperresponsiveness and gastroesophageal reflux disease (GERD). The patient was treated for GERD. Because the productive cough persisted, the patient underwent chest CT, fiberoptic bronchoscopy, and open lung biopsy. She was diagnosed with lipoid pneumonia. The patient was questioned regarding the use of lipid substances, and she reported the chronic use of evening primrose oil. After the discontinuation of the substance and the maintenance of GERD treatment, her condition improved.
