RESUMO
Malignant mesothelioma is an extremely aggressive tumor arising from the pleura with median survival of approximately 9-12 months. It can rarely present as a spontaneous pneumothorax. Less than 35 cases of malignant mesothelioma presenting as spontaneous pneumothorax have been reported in the literature. Pathology may show florid mesothelial hyperplasia. We herein report a case of mesothelioma presenting as a pneumothorax that gradually enlarged over a one-year period and also review the relevant literature.
RESUMO
Angiosarcoma is a rare but highly malignant tumor arising from vascular endothelial cells. Angiosarcoma commonly arises from the heart, liver, breast, and skin including the scalp. Angiosarcoma metastasizing to the lungs can present as either pneumothorax, hemothorax, or pleural effusions. They can rarely present as rapidly enlarging thin-walled pulmonary cysts. A review of the literature is included.
