A 9-year-old female domestic short-haired cat was brought in with a rapidly growing, painless swelling in her jaw that had developed over three weeks. After examining her and taking X-rays, the vet found a firm mass in her salivary gland. The cat underwent surgery to remove the tumor and received radiation therapy afterward. Unfortunately, seven weeks later, the cat was found to have lung metastasis (cancer spread), and treatment was stopped.

Abstract
The presence of a malignant mixed tumor, also known as a carcinosarcoma, in the salivary gland is very rare. Such tumors, which are typically aggressive, are characterized by the presence of carcinomatous and sarcomatous components. A 9-year-old neutered female domestic short-haired cat presented with swelling in the right mandibular lesion that had rapidly enlarged over the previous 3 weeks. Physical examination revealed a large, fluctuated and painless subcutaneous swelling that was associated with a firm mass. Radiographs of the head revealed a soft-tissue density that involved faint circular calcific opacity. Contrast-enhanced computed tomography revealed that the peripheral capsulated cystic area had a contrast enhanced region without bone lysis. The cat received a total excision of the mass and postoperative radiotherapy. Histopathological analysis of the mass revealed that it was a malignant mixed tumor. Metastasis to the lung was discovered 7 weeks later, at which time treatment was stopped.
