Surgical resection of a rare biatrial giant sarcoma: a case report.

Abstract

Primary cardiac undifferentiated sarcoma is an exceptionally rare entity, marked by nonspecific symptoms that considerably challenge its diagnosis and treatment. Surgical resection generally serves as the primary treatment modality. This article describes the case of a 32-year-old female patient admitted to the hospital with symptoms of abdominal distension and pain. Subsequent echocardiography revealed a cardiac tumor that occupied almost the entire left and right atria. The tumor was surgically removed in an emergency procedure, and subsequent pathological examination confirmed an undifferentiated sarcoma. The patient was successfully discharged 17 days after surgery. She then completed six cycles of chemotherapy. A six-month follow-up showed no signs of tumor recurrence or metastasis.
