title: Lethal mass mimicking myxoma in the heart.
abstract: A 70-year-old man presented in advanced heart failure with jaundice. Transthoracic echocardiography revealed a 21 × 24-mm mass in the left atrium attached to the posterior mitral valve leaflet. Surgical excision was attempted, but the tumor had infiltrated the entire left atrial wall and was deemed too extensive to be resectable. Histology confirmed a high-grade pleomorphic sarcoma with malignant fibrous histiocytoma-like features. Liver biopsy revealed a high-grade liver sarcoma.
