Between 1982 and 1990, 2388 brochoscopic examinations were carried out in patients with cancer in our hospital. A diagnosis of endobronchial metastasis was established in 30 patients (2.09 %), with the following primary tumors in descending order of frequency: breast, large bowel, melanoma, neuroblastoma, leiomyosarcoma and endometrial. Despite the rarity of endobronchial metastases secondary to colon adenocarcinoma, we were able to study 3 cases from our Center. In one case the diagnosis of endobronchial metastasis was simultaneous with that of the primary tumor, and in the other 2 this metastatic complication occurred 16 and 42 months, after the original diagnosis. When this complication occurred, the stage of the disease was advanced in all 3 cases: 2 were Dukes’ stage C and one stage D. Although this metastatic location usually implies a very negative prognosis as regards life expectancy, it did not seem to significantly reduce the latter in our patients.
