Benign Fibrous Histiocytoma of the Small Intestine in a Cow

A well circumscribed, firm nodule was found protruding from the duodenal wall of an adult cow at routine meat inspection. On the basis of morphological and immunophenotypic features, a diagnosis of benign fibrous histiocytoma (BFH) was established. Malignant fibrous histiocytoma has been reported previously in the cow, albeit rarely, but to the best of our knowledge this is the first recorded case of bovine intestinal BFH.
