Summary:At the post-mortem examination, a nodular mass of 3 cm in size was observed in the right atrium of a cow. The mass was highly elastic, and multiple small white nodules 5 mm in diameter were observed on the surface. Histopathologically, the mass was composed of large and small blood vessels, fibrous connective tissue, mature adipose tissue and cardiac muscle fibers. The vascular structure was irregular, and the vascular wall was markedly thickened by fibrous connective tissue. By special staining and immunohistochemical staining, it was confirmed that the main components of the vascular wall were collagen fibers, elastic fibers, smooth muscle and mucinous materials. Based on the above findings, the present case was diagnosed as cardiac vascular hamartoma.
