[Malignant non-Hodgkin's lymphoma in the superior vena cava and the right ventricle. A case report].

A 39-year old patient presented with small, sudden hemoptyses and a diagnosis of pulmonary tuberculosis was made on radiographic pleural and parenchymatous lesions but without bacteriological confirmation. Two years later, the patient was admitted to hospital following severe hemoptysis. Echocardiography revealed the presence of a tumour in the right ventricular outflow tract. At surgery, nodules were also resected from the superior vena cava. Histological examination of the surgical specimens suggested that the tumour was an angiosarcoma. Six months later, the patient returned complaining of a painful swelling in the left iliac fossa. Immuno-histochemical analysis of the cardiac and abdominal tumours finally concluded that it was in fact a malignant non-Hodgkinian lymphoma.
