A Primary Right Atrial Leiomyosarcoma in a 59-Year-Old Female Patient

Abstract

Primary cardiac tumors are rare tumors detected between 0.001% and 0.03% in autopsy series. The majority of primary cardiac tumors are benign and are often atrial myxomas, but up to 25% are malignant. Angiosarcomas are the most common primary malignant tumors, followed by rhabdomyosarcoma, mesothelioma, and fibrosarcoma. Among all cardiac sarcomas, leiomyosarcoma is rarely seen (approximately 8% of all cases). 1,2 In this study, we presented a case of primary cardiac leiomyosarcoma originating from the right atrium in a 59-year-old female patient. CASE REPORTA 59-year-old female patient with a history of diabetes and hypertension presented with complaints of difficulty in walking and weakness for a week. Abdominal ultrasonography (USG) and thorax computed tomography (CT) revealed bilateral pleural and pericardial effusion, therefore the patient was referred to our institution for further investigation of the effusion etiology. Transthoracic echocardiography revealed a 5x3.5 cm mass originating from the entrance of the pulmonary arteries. No extension to the vena
