Plain-English summary
A black-tailed prairie dog had a benign tumor in its salivary gland that was removed, but two years later, it developed a more serious malignant tumor in the same spot. Both tumors had similar features to those seen in humans with similar conditions. After the second surgery to remove the malignant tumor, the prairie dog was doing well and showed no signs of recurrence or spread of the disease nine months later.

Abstract
We describe a black-tailed prairie dog (Cynomys ludovicianus) with a benign biphasic nodular tumour that recurred as a malignant biphasic tumour at the same site 2 years after resection. Both tumours were biphasic with regard to the glandular epithelium and basal cells and contained little of the mucus, cartilage or fibrous tissue that characterize pleomorphic adenoma and carcinoma ex-pleomorphic adenoma. Both the first and second tumours exhibited histopathological features similar to those exhibited by human basal cell adenoma and adenocarcinoma, respectively. Both were resected and the animal was alive with no recurrence or metastasis at the time of writing, 9 months after the second surgery.
