Key result
Primary pulmonary sarcoma with left atrial invasion leads to lower extremity arterial tumor embolism after chemoradiotherapy.
Why the study?
Arterial tumor embolism is a fatal complication of human neoplasia with limited reported cases involving pulmonary sarcoma invading the left atrium.
Chemoradiotherapy for pulmonary sarcoma invading the left atrium may induce tumor shrinkage that precipitates acute arterial tumor embolization, requiring prompt embolectomy.
Alerts clinicians to embolization risk after chemoradiotherapy for left atrial-invading pulmonary sarcomas; extends tumor embolism spectrum but leaves practice implications open.
Arterial tumor embolism is a fatal complication of human neoplasia. Here, we report a case of an arterial tumor embolism in the lower limb that occurred after chemoradiotherapy for primary pulmonary sarcoma. Initially, the primary tumor had invaded the left atrium, originating from the right pulmonary vein.
