We receive samples from a nodular lesion in the myocardium from a 12-month-old\u00a0Friesian breed calf\u2019s carcass. The lesion measured 1cm in diameter, showed a white coloration and the margins were irregular with fibrous appearance. The inspectors wanted to rule out bovine cysticercosis.<\/p>\n

A histopathological study was performed which revealed a neoplastic proliferation of glandular appearance, formed by well differentiated cubic epithelial cells organized in an acinoductal pattern and were surrounded by large amounts of mature fibrous tissue. An immunohistochemical study against cytokeratin (CK 5, 6, 8, 17, 19) confirmed the epithelial origin of the neoplasm.<\/p>\n

This neoplasia receives the name of\u00a0myocardial adenomatoid tumor<\/strong> and it is a benign neoplasia that is usually reported as an incidental finding at slaughter because it usually is inconsequential to the live animal. The presence of abundant fibrous tissue at the histological examination explains the white coloration and firm consistency observed macroscopically. The bibliography speculates that the origin of this neoplasm is mesothelial (pericardium) due to his immunohistochemical characteristics.\u00a0The presence of cysticercosis was ruled out.
