Primary cardiac angiosarcoma is a very rare malignant tumor with very poor prognosis. Symptoms of the disease are nonspecific. One of the rare clinical presentations is diffuse pulmonary hemorrhage. A 61-year-old male was admitted to our clinic with the complaints of right side pain lasting for 10 days, cough and hemoptysis. The chest X-ray showed bilateral nodular lessions and increased cardiothoracic index. Thoracic computed tomography revealed cardiomegaly, showing a mass in 7x5 cm in the anterolateral right atrium with ground-glass appearance, predominantly in the mid and lower zones of bilateral lung fields. Echocardiography showed dilatation and hypertrophy of the left ventricle. The case underwent surgery with the initial diagnosis of myxoma. During surgery, cardiac angiosarcoma was diagnosed. The patient died due to respiratory failure soon after surgery. In this article, we present a case report, discussing the details of the diagnostic process based on pulmonary symptoms along with certain challenges.
