Pancreatic carcinoma. Light micrograph of a section through an adenocarcinoma of the ducts of a human pancreas. An adenocarcinoma is a cancer of glandular tissue which arises from epithelial (lining) cells. Here, the cancer comes from the lining cells of the pancreatic ducts. The ducts allow the passage of pancreatic fluid (mainly digestive enzymes) into the intestines. Here, the cells lining the duct possess nuclei (dark purple) of varying sizes (pleomorphism), and the majority are large and irregular. Pancreatic cancers have an insidious manner of growth, and generally cause no severe symptoms until they reach a terminal stage. Magnification unknown.
