Plain-English summary
A 10-year-old horse was found to have a liver tumor that had not been previously recognized in horses. This tumor, which measured about 16 centimeters across, looked similar to a type of tumor seen in humans and was made up of complex structures surrounded by a lot of fibrous tissue. While this type of tumor is known in other animals, particularly cats, it appears to be a unique version in horses. The researchers suggest that this tumor could be a different form of a biliary cystadenoma, which is a type of liver tumor. Overall, this case highlights a new finding in equine health, but it does not provide information on treatment or outcome.
Abstract
Hepatic biliary cystadenoma is a well-delineated neoplasm in some domestic animals, especially in cats, but it has not been reported in equines. We report on a case of hepatic biliary tumor, incidentally found in a 10-year-old horse, with gross and microscopic features similar to those observed in biliary adenofibroma of humans. The tumor presented as a solid mass measuring 16 cm in diameter and histologically was composed of complex tubulocystic biliary components embedded in an abundant fibrotic stroma. We regarded this tumor as a morphological variant of biliary cystadenoma of domestic animals. Differential diagnoses from other hepatic biliary tumor-like and tumor lesions are provided.
