Linfoma metastásico cardíaco

secondary or metastatic cardiac tumors are 20 to 40 times more common than primary benign or malignant neoplasms. lung and breast carcinoma, malignant melanoma, and, to a lesser degree, leukemia and lymphoma, often metastasize to the heart. we describe the case of a 36-year old female patient with arrhythmia and echocardiographic evidence of a rapidly growing heart tumor. treatment with systemic corticosteroids was initiated due to symptoms aggravation and the patient improved within 72 hours. a metastatic tumor was then suspected. a gastric biopsy confirmed the presence of a non-hodgkin lymphoma. specific cytostatic treatment was started; the patient remains in remission with complete regression of cardiovascular symptoms. interestingly, our patient presented only cardiovascular symptoms despite the primary tumor was located in the digestive system.
