title: Cardiac tamponade due to malignant pericardial effusion in breast cancer: a case report.
abstract: Cardiac tamponade resulting from malignant pericardial effusion is an uncommon initial presentation of various extracardiac malignancies. Only twenty-nine cases of extracellular malignancies with this initial presentation have been previously published. Lung carcinoma leads as the most common malignancy involved, followed by carcinoma of the stomach, pancreas, kidney and ovary, mediastinal rhabdomyosarcoma, malignant lymphoma and leukemia. This report describes a case of breast carcinoma in a 47-year-old woman who initially presented with cardiac tamponade. To the best of the authors' knowledge, no similar case has even been reported in the literature.
