Endobronchial metastasis from rectal adenocarcinoma: report of a case.
We herein report a case of late endobronchial metastasis after the resection of a primary rectal adenocarcinoma. A 51-year-old man underwent a resection of rectal adenocarcinoma. Five years postoperatively, he underwent a right sleeve upper lobectomy for a right endobronchial tumor. The resected tumor was diagnosed to be endobronchial metastasis from rectal adenocarcinoma. Therefore, the relationship between the two tumors was analyzed using deoxyribonucleic acid (DNA) flow cytometry and immunohistochemical staining. Endobronchial adenocarcinoma had strong homogeneous staining patterns and identical biochemical characteristics to rectal adenocarcinoma.
