Adrenocortical carcinoma in a donkey

An adrenocortical carcinoma was found in an eight-year-old male donkey. The main clinical feature was severe depression and inappetence. The animal died 24 hours after hospitalization. Necropsy revealed a large tumor around the anterior pole of the left kidney and metastases to liver, heart and lung. Fibrous adhesions were seen between the tumor and the intestinal serosa. The abdominal cavity contained a large amount of red-brown fluid.
