Abstract
Primary pulmonary epithelioid angiosarcoma is an extremely rare malignancy. Herein, we report the case of an elderly Chinese patient with primary pulmonary epithelioid angiosarcoma. The 72-year-old man presented with a 1-month history of persistent hemoptysis and left chest pain and weight loss of 3 kg. A chest computed tomography (CT) scan revealed two masses (maximum size 3.0 cm x 2.0 cm and 0.8 cm x 0.5 cm) in right lower lobe. We performed a left thoracotomy for tumor resection. Pathological examination showed that there was a significant amount of hemorrhage, fibrinous exudates, degeneration, and necrosis. With immunohistochemical analysis, tumor cells had strong expression of CD34, FLI-1, vimentin. Morphological and immunohistochemical findings supported the diagnosis of epithelioid angiosarcoma.
