[Does heart sarcoma mimick lupus erythematosus and vasculitis? Report of 2 cases].

Abstract

Primary heart tumors are rare. The most common one is myxoma. It may synthetize IL-6 and frequently shown systemic clinical manifestations that confuse the diagnosis. Primary heart sarcomas are even more rare, as far as we know they have been not associated with systemic illnesses. We observed two cases with a presumptive diagnosis of systemic lupus erythematosus who were identified as primary sarcomatous heart neoplasms after surgical excision.
