[Pulmonary metastasis of the stomach cancer]

Despite the fact that the lungs have a plenty of blood and lymphatic supply, only 20-40% of pulmonary metastasis from the stomach cancer are found. Pulmonary metastases are most commonly described as well-circumscribed lesions complicated with hilar metastasis. However, the most important picture is that of diffuse lymphatic permeation, which may produce clinical and radiologic features of lymphangitis carcinomatosa showing a characteristic roentgenologic appearance, namely, a fine feathery interstitial streaking. Furthermore, pleuritis carcinomatosa is a common type of metastasis from the stomach cancer and often presents a difficult management problem. Instillation of cytotoxic or sclerosing agents into the pleural space can be effective in preventing recurrence.
