Abstract
- It has been well known that angiosarcoma (AS), particularly scalp AS, metastasizes to the lungs with multiple air-filled cystic lesions on chest computed tomography scans. Pneumothorax, due to cystic lesion rupture into the pleural space, is frequent; however, we do not exactly know how rapidly the metastatic lesions spread to the lungs or what the exact pathogenetic mechanism for cystic metastasis is. According to our experience, the speed of disease progression in pulmonary metastasis is relatively fast and the entire lungs may be involved within two or three months. The infiltrating spindle cell tumors in the alveolar walls are tethering the adjacent alveolar spaces in order to form a dilated air-filled cystic lesion.
