[Pericardial effusion due to metastatic prostate cancer: a case report].

We describe a patient whose complaints were related to pericardial effusion due to prostatic carcinoma. An 80-year-old man was admitted to our hospital because of chest discomfort and dyspnea. The chest radiograph revealed cardiomegaly and computed tomographic scan showed a large pericardial effusion. Pericardiocentesis revealed sanguinous exudates. Cytologic study suggested metastatic adenocarcinoma or malignant mesothelioma. He died suddenly because of ventricular tachycardia. At autopsy, the major finding was poorly differentiated adenocarcinoma of the prostate with metastases to the mediastinum.
