Primary pulmonary angiosarcoma is a rare cause of intractable hemoptysis that may require pneumonectomy.
Angiosarcomas are rare tumors, and primary pulmonary location has only been reported in very few cases. In the present report a patient with severe, intractable hemoptysis, demanding pneumonectomy, was found to have a single, small angiosarcoma eroding a large bronchus. No sign of tumor-spread to other organs was detected. A review is made of previous reports of angiosarcomas of the lung, and the differential diagnoses are discussed.
