Fatal secondary pulmonary hypertension due to cardiac involvement in AIDS-associated Burkitt's lymphoma.

Primary cardiac lymphomas are rare lesions in children with acquired immunodeficiency syndrome (AIDS). Most of them are high-grade Burkitt's or Burkitt-like lymphomas. They usually present with congestive cardiac failure, pericardial effusion or tamponade, arrhythmias, with predominant systemic 'B' symptoms and often with widespread extranodal involvement.
