Metastatic Lymphoma in a Rabbit (Oryctolagus cuniculus)

AbstractA White Giant male rabbit (13 months old) was treated for chronic weight loss, cessation of faecal production and suspected wool block in the intestine at Southern Regional Research Centre (ICAR-Central Sheep and Wool Research Institute), Mannavanur (Tamil Nadu). Palliative therapy was not successful and the animal succumbed on 5th day. On necropsy, nodular protruding lesions on the renal cortex were found that disfigured renal architecture. The renal pelvis was fleshy and dark red in colour. Caecal appendix was enlarged and ecchymotic haemorrhages were seen inside the lumen. On histopathological examination, lymphoblastic infiltrations were seen in the liver, spleen, lung and caecal appendix, suggestive of lymphoid tumour metastasised to visceral organs.
