Summary
Endobronchial metastases (EBM) are rare and can be asymptomatic, occurring synchronously or late. This study identified common histopathological findings and upper lobe predilection in EBM cases.
Area of Science:
- Pulmonology
- Oncology
- Pathology
Background:
- Distinguishing endobronchial metastases (EBM) from primary lung cancers and benign lesions is crucial for appropriate treatment.
- Endobronchial metastases represent a rare metastatic pathway to the airways.
Purpose of the Study:
- To document the clinicopathological characteristics of EBM.
- To identify potential distinguishing features of EBM.
Main Methods:
- Retrospective analysis of 18 histological EBM cases diagnosed via bronchoscopic bronchial biopsy.
- Assessment of clinical symptoms, primary tumor sites, radiological and bronchoscopic features, and histopathological properties.
Main Results:
- EBM occurred in 18 patients, with primary sites including colorectal, breast, and renal cancers.
- Common symptoms were hemoptysis and cough; however, three patients were asymptomatic.
- EBM showed a predilection for upper lobes, with polypoid or infiltrative endoscopic appearances and common lymphocytic inflammation.
Conclusions:
- Endobronchial metastases are rare, can be synchronous or delayed, and may present asymptomatically.
- Upper lobe involvement and lymphocytic inflammation are frequent findings in EBM.
- Further research is needed to elucidate the clinical significance of EBM.
