[Complete regression of cardiac non-Hodgkin's lymphoma after 23 months with chemotherapy].

The authors report the case of a non-Hodgkin malignant lymphoma (NHL) of the heart presenting with syncope. The diagnosis of a cardiac tumours was made by echocardiography. Myocardial biopsy enabled diagnosis of a highly malignant NHL in a patient with a history of low grade NHL. Chemotherapy with CNOP (Cyclophosphamide, Novantrone, Oncovin, Prednisone) induced total regression of the tumour. The patient is in total remission 23 months later. The authors emphasise the value of echocardiography in the diagnosis and follow-up of this pathology. The case is also noteworthy because of the unusual transformation of a low grade to a high grade cardiac NHL.
