Introduction:
Diagnosis of endobronchial metastases is facilitated by immunolabeling techniques on bronchial biopsy samples.
Case:
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.
Comments:
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.
