Extensive Primary Cardiac Lymphoma Diagnosed by Percutaneous Endomyocardial Biopsy

Cardiac Amyloidosis Diagnosed by Endomyocardial Biopsy

Intracavitary cardiac melanoma diagnosed by endomyocardial left ventricular biopsy.

A patient was evaluated for a persistent pericardial effusion and on two-dimensional echocardiography was found to have an intracavitary left ventricular mass. Twenty-two years earlier, a melanoma of the ethmoid sinus had been excised. An electrocardiogram revealed impressive T-wave abnormalities and pathologic Q waves, initially suggestive of "myocardial infarction." However, the coronary arte...

[Primary cardiac lymphoma: diagnosis by transjugular biopsy].

Primary cardiac lymphoma, defined as a non-Hodgkin's lymphoma involving only the heart and pericardium, is an extremely rare malignancy. It should be suspected in patients with a heart mass and heart failure, unexplained refractory pericardial effusion or rhythm disturbances. Transvenous intracardiac tumor biopsy under fluoroscopic or transesophageal echocardiographic guidance, is a minimally i...

Intracardiac sarcoma diagnosed by left ventricular endomyocardial biopsy.

Angiotropic lymphoma diagnosed by muscle biopsy.

On hospitalization, the clinical examination of a 64-year-old female with polyarthralgia and an elevated fever revealed leukocytosis, an increased lactic acid dehydrogenase level, and a positivity for the C-reactive protein. Subsequently, the patient developed muscular pain in the lower limbs. Thus, a muscle biopsy was performed and B-cells with atypia were detected in the arteriolar lumen with...
