Abstract
We present herein the case of a 48-year-old woman with a benign mediastinal teratoma that had been followed up for 3 years, who developed acute cardiac tamponade. The patient had initially undergone an exploratory sternotomy, at which time the tumor was histologically diagnosed as a benign mature teratoma that could not be resected due to its severe, wide adhesion to the surrounding organs. However, following the development of cardiac tamponade, both sternotomy and right intercostal thoracotomy were employed, and the tumor could be excised with cardiopulmonary bypass standby. High levels of amylase and carbohydrate antigen 19–9 were revealed in the pericardiac effusion fluid. The mRNA expression of inflammatory cytokines including interleukin-1 (IL-1), IL-6, and IL-8 in the tumor tissue was also demonstrated by a reverse transcriptase-polymerase chain reaction analysis. This case illustrates the ultimate natural course of benign mediastinal teratoma and emphasizes the importance of early surgical excision, even when this tumor is asymptomatic.
