“A Spontaneous Case of Appendicitis in Rabbit (Oryctolagus cuniculus)”

 

 

The popularity of rabbit as a companion animal has been increasing recently. Therefore, knowing the pathology of this species is important for veterinary practitioners. In animals, spontaneous appendicitis occurs only in non-human primates and rabbit; however, it is not often encountered in the rabbit. Here, we report a natural case of appendicitis in a rabbit. An 8-months old female Holland Lop rabbit was presented with clinical signs of anorexia and lethargy. An abdominal mass was found in the lower abdomen. The mass was adhering with the cecum, urinary bladder, ureter, and the abdominal wall. The mass was surgically excised. Microscopically, destruction of the mucosal lining epithelium and extensive necrosis of lymphoid follicles were seen. Many heterophils, residual foods and bacteria were found inside the lumen in association with necrotic debris. Based on clinical and histopathological findings, this case was diagnosed as appendicitis. Our findings will help understanding the etiopathogenesis of appendicitis in rabbit.
