Unusual presentation of multiple recurrent cardiac sarcomas as acute acalculous cholecystitis caused by rapid expansion into the right cardiac chamber: report of a case.

Sarcomas are rare malignant cardiac tumors and their prognosis is extremely poor, with a high recurrence rate despite extensive initial surgical resection. The development of therapeutic alternatives looks bleak for recurrent sarcomas, however, and complete surgical resection is crucial for any hope of survival even for the recurrent patients. We herein report the case of a 38-year-old male patient with multiple recurrent cardiac sarcomas causing acute acalculous cholecystitis 20 months after the resection of the primary tumor.
