[Endobronchial metastases of rectal adenocarcinoma].
BACKGROUND
Diagnosis of endobronchial metastases is facilitated by immunolabeling techniques on bronchial biopsy samples.


METHODS
Endobronchial tumors appeared in a 70-year-old woman with an adenocarcinoma of the crypts of Lieberkuhn, diagnosed two years previously. Immunohistochemical examinations made it possible to diagnose endobronchial metastases of the rectal adenocarcinoma.


CONCLUSIONS
The endobronchial zone is a relatively rare metastatic site. Metastases associated with rectal adenocarcinoma account for 11-26% of secondary endobronchial lesions. After endoscopic biopsy, immunolabeling techniques help to differentiate between primary adenocarcinoma and endobronchial metastasis. Prognosis is poor.
