This case represents the first reported instance of a nonvisceral soft-tissue leiomyosarcoma metastasizing solely to the heart, occurring 14 years after the complete resection of the primary tumor.

Clinicians should consider late cardiac metastasis in sarcoma patients with SVC syndrome; leaves open optimal surveillance duration.
Metastasis of a nonvisceral leiomyosarcoma to the heart is rare. We present the case of a man with a history of an upper extremity cancerous lesion that was completely resected with appropriate surveillance monitoring, which then metastasized to the heart 14 years later, presenting as superior vena cava syndrome. Full evaluation found no other metastatic lesions, including no residual sarcoma at the former primary site. We include transthoracic echocardiography and computed tomography images of unusual presentation of the large mass extending from the caudal superior vena cava to the right atrium and into the right ventricle across the tricuspid valve.
