A rare case of tumor of porcine pancreas was found in a four-year-old, good breeding Duroc sow weighing 250 kg. It had delivered offspring two times without abnormalities. After the second delivery, it showed weak sexual excitement and sterility for 6 months. It was well-constructed, but emaciated with rough coat and several crusts due to trauma. Necropsy revealed the irregularly enlarged pancreas completely replaced with neoplastic nodules of various sizes. Spheroidal secondary tumor masses were disseminated on the serosal surfaces of spleen, omentum, liver, stomach and diaphragm. No tumor nodules were seen on the intestinal sv, rosa or mesentery.
From histological findings, this tumor was diagnosed as well-differentiated papillotubular adenocarcinoma derived from the pancreatic duct.
