What is Pancreatic Carcinoid Tumor?

Pancreatic Carcinoid Tumor
Pancreatic Carcinoid Tumor. Hematoxylin and eosin (HE) and specific immunohistochemical staining for NSE, Syn, CgA, and CK in samples from patient no. 3, a 46-year-old female, with a one-month history of backache. (A) HE, ×100 magnification; (B) HE, ×400 magnification; (C) NSE+++, ×200 magnification; (D) CK++, ×200 magnification; (E) CgA+, ×200 magnification; and (F) Syn+, ×200 magnification. Tumor cells with identical shape, regular arrangement, and abundant cytoplasm were observed. Fine particles, and small and round nuclei were found in the middle of the cells by eosin staining. Chromatin was fine and uniform. Nuclear fission was often apparent. NSE, CK, CgA, and Syn particles were located in the plasma of the tumor cells, with no expression in the intercellular substance. Computed tomography indicated that the mass was 4.5 cm3 and located on the tail of the pancreas. Distal pancreatectomy was performed. This patient was followed up until August 2011, with no signs of metastasis for 21 months. NSE, neuron-specific enolase; CK, cytokeratin; CgA, chromogranin A; Syn, synaptophysin.
