Giant metastatic alveolar soft part sarcoma in the left ventricle: Appearance in echocardiography, magnetic resonance imaging, and histopathology

Abstract

Alveolar soft part sarcoma is a rare soft-tissue neoplasm that accounts for <1% of all soft-tissue sarcomas. Most cases arise in the extremities and head and neck region of young adults. The common sites of metastasis are lung, brain, and bone. Cardiac metastasis is extremely rare, in particular. Here we present the diagnostic evaluation and successful surgical resection of such a cardiac tumor in a patient aged 50 years with a histology-confirmed diagnosis of metastatic alveolar soft part sarcoma. © 2011 Wiley Periodicals, Inc.
