Abstract:
The present study describes the pathomorphological observations of lipoma in an adult bull. A carcass of an adult bull was presented to the Department of Veterinary Pathology, College of Veterinary Sciences of the Lala Lajpat Rai University of Veterinary and Animal Sciences (LUVAS), Hisar for necropsy. Animal was not showing any signs of illness before death. Grossly, the tracheal mucosa appeared severely congested and haemorrhagic. Lungs showed diffuse congestion and haemorrhages. Petechial to ecchymotic haemorrhages were present on the pericardium and spleen. On gross examination, coarsely lobulated yellow coloured tumorous mass of soft consistency was found diffused in omentum, mesentery and around the kidneys. Cut surface of neoplastic mass was yellow and oily in nature. Histopathologically, tumorous mass revealed large mature adipocytes with eccentric nucleus, separated by the fibrous connective tissue septa. At some places fatty cysts along with congestion, haemorrhages and inflammatory cells were also evident. Microscopic examination of heart revealed numerous sarcocysts along with myocardial congestion and haemorrhages in the pericardium. Spleen showed capsular thickening accompanied with haemorrhages and lymphocytic depletion in the white pulp area. Focal interstitial nephritis, cellular swelling, congestion and haemorrhages were prominent changes in the kidney parenchyma. Lungs revealed vascular changes. In conclusion, Histopathological findings suggested the tumorous growth to be lipoma. Lipoma may not cause acute problems but as they become large, can interfere with normal body functions.
