Abstract:
Case: A 62-year-old woman underwent high anterior resection and partial lobectomy for colon cancer and lung metastasis, respectively, and postoperative chemotherapy. During the follow-up period, she visited the Department of Otolaryngology at our hospital, complaining of expectoration of a mass. Laryngeal fiberscopy showed no abnormality, but thoracic computed tomography revealed nodular lesions protruding into the bronchial lumen. Bronchoscopy confirmed the presence of multiple granular nodules protruding from the bronchial wall. The nodules had a polyp-like appearance and were easily dissected or detached. Anti-cancer drug therapy was initiated for endobronchial metastases from colorectal cancer diagnosed in transbronchial biopsy. Conclusion: This was a rare case of endobronchial metastases that were discovered after expectoration of tumor masses. Bronchoscopic findings were extremely unusual, showing multiple tumors that were easily detached because of their extremely weak connection to the bronchial wall. The findings suggest that it is important to consider endobronchial metastasis from colorectal cancer and perform early diagnostic imaging and bronchoscopy when patients present with recurrent expectoration of masses after surgery for colon cancer.
