A 48-yr-old captive white rhinoceros ( Ceratotherium simum ) was euthanized due to old age, pododermatitis, and progressive laminitis of the middle toe of the left fore- and hindlimbs. Severe chronic necrotizing periodontitis and dental loss was diagnosed, although food intake prior to death had not decreased. In addition, extensive ulceration of the tongue was noted. Histologically, squamous cell carcinoma of the tongue was diagnosed with chronic severe ulcerative glossitis. Metastatic lesions were not detected. Clinicians should monitor the oral health of aging rhinoceros due to the occult nature of these lesions.
一头48岁的圈养白犀牛（白犀属）因年老、足部皮炎以及左前肢和后肢中趾渐进性蹄叶炎而实施安乐死。尽管死前食物摄入量未减少，但仍诊断出患有严重的慢性坏死性牙周炎和牙齿脱落。此外，还发现舌头有广泛溃疡。组织学检查诊断为舌鳞状细胞癌伴慢性严重溃疡性舌炎，未检测到转移病灶。由于这些病变具有隐匿性，临床医生应监测老龄犀牛的口腔健康状况。
