Abstract
This report describes the clinical, haematobiochemical, ultrasonographical and pathological findings in a female Arabian camel with renal cell carcinoma. The she camel had a history of weight loss, abdominal pain and red urine. Rectal palpation revealed an enlarged mass at the right kidney which distorted its normal conformation. Centrifugation of a urine sample yielded red sediment. Alterations in haematological and biochemical parameters included a decreased hematocrit per cent, red blood cell counts, haemoglobin concentration, total protein, albumin and globulin, and increased glucose, creatinine, sodium and potassium concentrations. Increase in the serum activity of aspartate aminotransferase and creatine kinase were also detected. Ultrasonographically, a caudally protruded, large, irregular shaped, hypoechoic and cavitated mass involving the right renal parenchyma was monitored. However, the left kidney subjectively appeared normal. At necropsy, haemorrhagic, irregular shaped and cavitated tumour involving the right kidney was detected. The right kidney was mostly pelvic. Compared to a weight of 1.5 Kg of the left, the right kidney weighed 18 Kg. Histopathologically, renal cell carcinoma showing tubular differentiation with malignant epithelial lining and nuclear anaplasia was suggested. No metastasis was found in other organs.
