Angiosarcoma metastasizing to the lungs can rarely present as rapidly enlarging thin-walled pulmonary cysts, alongside pneumothorax, hemothorax, or pleural effusions.
Case Report (n=1)
Highlights a rare presentation of metastatic angiosarcoma as rapidly enlarging thin-walled pulmonary cysts.
Clinicians should consider angiosarcoma in unexplained enlarging pulmonary cysts with pneumothorax; case reports leave open its true frequency and diagnostic utility.
