title: Mediastinal lymphosarcoma simulating pericarditis.
abstract: A case of lymphosarcoma of the heart in a 10-year-old boy is presented. The clinical picture simulated a pericarditis. Prednisolone had a remarkably good temporary effect. Post-mortem examination showed a highly differentiated lymphosarcoma invading the pericardium and myocardium from a primary mediastinal localisation. Cytologic examination for malignant cells in the pericardial fluid must not be forgotten in a case of unexplained pericardial effusion.
