Introduction: Neuroendocrine tumors (NET) of the pancreas are slow growing neoplasms, but they can metastasize after many years after surgery.
Aim(s): To evaluate the role of cytokeratin 19 (CK 19) expression in NETs of different origin.
Materials and methods: We conducted a comparative study of CK19 expression in 211 NET specimens: pancreas - 118, gut - 35, lung - 21, stomach - 15, thymus - 6, metastases with unknown primary localization -16. Metastases were revealed in 28 cases NET of the pancreas (23,7%), in 15 (42,9%) - gut, in 10 (66,7%) -stomach, in 6 (28,6%) - lung and in 3 (50%) - thymus.
