Abstract

Pulmonary metastatic angiosarcoma usually reveals multiple nodular lesions associated with parenchymal hemorrhage. It is presented, in rare cases, as multiple emphysematous cystic lesions, complicated by pneumothorax. We experienced a case of pulmonary metastastasis from angiosarcoma of the scalp in a 58-year-old male showing multiple thin-walled emphysematous cystic lesions. The tumor cells spread along the subpleural and interlobular septa, focally surrounding the cystic lesions. This case suggests that a rare metastatic pattern seen in angiosarcoma of the scalp should be considered as a differential diagnosis of bullous emphysematous lesion.
