“…The incidence rate of EEM ranges from 2% to 50% for pulmonary metastases from extrathoracic neoplasms 7,8 . There are few observed cases of localized EEM of primary lung adenocarcinoma 1,2,9 . Although it is often difficult to distinguish between EEM and MPLC, we succeeded in diagnosing EEM and propose a mechanism of metastasis via the lymphatic vessels, based on the pathological homology and characteristics of this case.…”

Lung adenocarcinoma with repetitive endotracheal/endobronchial metastasis 20 years after surgery: A case report

The occurrence of endotracheal/endobronchial metastasis (EEM) after complete resection of a primary lung cancer is rare. Here, we report the case of an 86-year-old woman in whom EEM occurred twice over a 20-year period following complete resection of a primary adenocarcinoma localized to the left main bronchus and trachea. The presence of EEM was confirmed by establishing immunohistochemical homology of the metastases with the primary tumor. To the best of our knowledge, this is the first reported case of repetitive EEM of primary lung adenocarcinoma. Lymphatic invasion in the primary lesion suggested that a possible route for EEM was the peripheral lymphatic tract, explaining the slow recurrence rate. We conclude that observation of the trachea/bronchus over a long period post operation could be important in monitoring for EEM, particularly if lymphatic invasion is confirmed in the primary tumor.

“…6 We reviewed the English-language and Japanese-language medical literature reporting endobronchial metastasis from lung cancer and identified 16 cases. 4,[7][8][9][10][11][12][13][14] Table 1 summarizes the clinical characteristics of these 16 cases in addition to the present case (17 cases). All cases involved men (17/17 cases).…”

We report a case of squamous cell lung cancer with transbronchial dissemination in a 73-year-old man. Bronchoscopic examination revealed multiple bronchial mucosal nodules that existed independently of one another. We reviewed 16 previous cases of endobronchial metastasis in lung cancer. All patients were men. Among the reports that described the smoking history, most patients were smokers (6/7), and the most frequent histological type of cancer was squamous cell carcinoma (11/17). Although hematogenous and lymphogenous routes have been reported as metastatic mechanisms, no previous cases involving transbronchial dissemination have been described. Transbronchial dissemination may be an alternative pathway of endobronchial metastasis.
