Carotid Body Tumor in a Cow

Abstract

A carotid body tumor was found closely attached to the left carotid artery of a cow. The neoplastic tissue was well defined, and no metastases were observed, but there was a slight invasion of the capsule. Histologically, there was great resemblance to the corresponding tumor in dogs: pleomorphic cells, numerous vessels, peritheliomatous patterns, i.e. predominantly epithelial cells lined by endothelium, and pseudoalveoli enclosed by reticulum.
