Fig 2 Histological analysis indicates the presence of a benign teratoma (asterisk) located inside the pericardium (arrowhead) with endodermic (ciliated and prismatic epithelium) and mesodermic (smooth musculature) components. No areas of dysplasia are identified supporting the diagnosis of benign mature intrapericardial teratoma. (Hematoxylin and eosin; ×40.)
