Plain-English summary
A 12-year-old mixed-breed cat was found to have a large mass in its liver after an ultrasound and CT scan. The tumor was surgically removed, and it was identified as a rare type of cancer called carcinosarcoma, which likely started in the bile ducts. Unfortunately, this type of cancer usually has a poor outlook, but the surgery offered the best chance for recovery. The cat's condition after surgery would depend on follow-up care and monitoring for any signs of recurrence.

Abstract
A 12-year-old, mixed-breed domestic cat was diagnosed with a multicystic hepatic mass via ultrasonographic examination and computer tomography scan. The tumor associated with the left medial liver lobe, and connected by a thin stalk to the hilar region, was surgically removed. The mass was firm, encapsulated, mottled white to red black, multinodular, and cystic. Histologic diagnosis was carcinosarcoma supported by positive immunohistochemistry for cytokeratins and vimentin of atypical neoplastic cell populations. On the basis of morphology, the origin was considered to be in the biliary tract. Biliary carcinosarcoma is a rare neoplasm that occurs in people. The epidemiology and risk factors have not yet been determined, and the prognosis is poor except for cases in which curative resection is performed.
