Lymphangiomyomatosis was first reported more than forty years ago. Although its incidence is rare, its occurrence is being increasingly recognized and has been the subject of a growing number of cases reports in recent years. This study adds 2 more cases to the file. Both cases involved young women with the characteristic symptoms of dyspnea, cough, abdominal discomfort and swelling, chest pain, and hemoptysis, with abundant formation of refractory chylous, serous ascites. Although the progression of the disease differed in each case, pulmonary function was affected in a similar way by the presence of obstructive and restrictive defects and a decrease in diffusing capacity. Underlying abnormalities were dilated lymphatics, thickened lymphatic walls, and muscular proliferation of leiomyomatous origin, leading to bronchial restriction. The authors point to the subtlety required in arriving at a differentiated diagnosis of lymphangiomyomatosis lymphangioleiomyomatosis and the difference between the two conditions. They also make particular recommendations in respect to the importance of preliminary hormone receptor tests and to the wisdom to be exercised in ligating a main lymphatic duct in the chest to control the formation of ascites. Pneumothorax, a frequent manifestation of lymphangiomyomatosis, is found to be the result of chronic air trapping due to a combination of narrowing of conducting airways and disruption of normal lung parenchyma.

A 42-year-old woman, who had received right breast-conserving therapy 5 years previously, was admitted with hemoptysis. Chest X-rays showed a tumor shadow in the left pulmonary hilus with partial atelectasis in the left lower lobe. Bronchofiberscopic examination showed a polypoid tumor arising from the endobronchial wall, with bleeding and a white surface coat. Although, microscopically, the tumor resembled the breast cancer resected previously, as we could not rule out primary lung carcinoma, and as the tumor seemed to be localized, thoracotomy was performed. During posterolateral thoracotomy, however, pleural metastatic nodules were found; therefore, only sampling of these nodules and the administration of 50 mg of cisplatin (CDDP) into the thoracic cavity were performed. From a comparison of the histopathological features of the original tumor and the intrathoracic tumor, and from the hormone receptor positivity of the pleural metastasis, we diagnosed the intrathoracic tumor as being highly suspicious of metastasis from breast cancer. The measurement of hormone receptor was informative for the diagnosis of and for selecting a therapeutic strategy for the metastatic breast cancer.
