Hepatocellular adenocarcinoma in a racing pigeon

摘要

Primary hepatic tumours are rare in birds. The aim of this paper is to present a case of hepatocellular adenocarcinoma (hepatocellular adenocarcinoma) in an 8-month-old racing pigeon. Dominant symptoms in clinical examinations included lack of appetite, dyspnoea and apathy. Physical examinations revealed a perceptible mass in the anterior part of the visceral cavity. Moreover, radiological examination revealed asymmetric enlargement of the liver and the presence of fluid in the visceral cavity. Ultrasonographic examination confirmed multifocal lesions in the liver tissue. Histopathological examination of the liver revealed tumour cells forming into glandular ducts, with malignant properties and a moderate level of diversification. No description ofhepatocellular adenocarcinoma in a racing pigeon has been found in the available literature.
