A four-and-a-half-year-old female Scottish Fold cat underwent partial pancreatectomy with en-bloc splenectomy. The resected specimen was a biphasic tumor that was diagnosed histologically and immunohistochemically as pancreatic adenosquamous carcinoma (ASC), a ductal carcinoma variant according to the WHO classification of tumors in humans. There was a gradual transition between the adenocarcinoma component and the squamous cell carcinoma component. The squamous cell carcinoma component comprised approximately 30–40% of the tumor. A pancreatic tumor infiltrated into the gastrosplenic ligament and spleen with regional lymph node and mesenteric metastases. Pancreatic ASC has not been reported in animals. This is a case report of feline pancreatic ASC with splenic involvement.
