A Case of Adenocarcinoma of the Lung with Endotracheobroncheal Metastasis

Abstract

A 71-year-old male case of adenocarcinoma of the lung (T2, N2, M1), was treated with CDDP, MMC and VDS. He showed partial response after one course of chemotherapy, but he was readmitted because of hemoptysis. Bronchoscopic findings revealed a smooth-surfaced polypoid tumor located in the posterior wall of trachea and another irregular tumor exposed in the lateral wall of the left main bronchus. Histological examination of the biopsied specimens showed metastasis of the lung cancer. At autopsy, the tumor had infiltrated, replacing the epithelium of the trachea and left main bronchus, and tumor cells were found in the submucosal lymphatic vessels. We concluded that the endotracheobroncheal tumors resulted from lymphogenic metastasis of lung cancer.
