Pancytokeratin is a type of protein that is part of the cytoskeletal structure in epithelial cells, consisting of a mixture of different keratin types. It is commonly used as a marker in immunohistochemistry to identify epithelial origin in tumors, helping to differentiate between various types of cancers. The detection of pancytokeratin can indicate the presence of carcinoma, making it a valuable tool in diagnostic pathology.
