Abstract

During four years, we had an opportunity to follow over 200 pulmonary metastasis cases but the report isrestricted to 81 cases that have been regarded as having satisfactory histological proof of the primary malignanttumor. For presentage distribution of lung metastasis and age incidence were also reviewed. 1. All 81 cases confirmed by biopsy and showed coarse nodular type pulmonary metastasis in 47.3 percent, lympathic type metastasisin 34.6 percent, golf type pulmonary metastasis in 8.6 percent, miliary type pulmonary metastasis in 6.2 percentand pneumonic type pulmonary metastasis in 3.7 percent. 2. 95 percent of hepatoma cases showed coarse nodular type metastasis to the lung and 5 percent of case of hepatoma showed miliary type pulmonary metastasis. In 13 cases of chorion epithelioma, 69.2 percent showed coarse nodular type pulmonary metastasis and 30.8 percent revealed golfball type pulmonary metastasis. In 7 cases of breast cancer, 85.7 percent showed lympathic type pulmonary metastasis and 14.3 percent had golf ball type pulmonary metastasis. In 4 cases of leukemia, 75 percent showed lympathic type pulmonary metastasis and 25 percent showed pneumonic type of pulmonary metastasis. 3. In 81 cases of pulmonary metastasis from primary malignant tumor, age incidence and frequency of pulmonary metastasis were deomonstrated on the table 1.
