Definition

Neuroendocrine neoplasm (NEN) is a general term including a broad family of neoplasms with neural and endocrine features. NENs may be localized in pure endocrine organs (tyroid, parathyroid and adrenal glands), nerve plexuses, extraadrenal paraganglia (paragangliomas) and diffuse endocrine system in different organs including gastrointestinal tract. Fourteen different cell types, producing variety of hormones have been described as components of diffuse endocrine system. Neuroendocrine cells of diffuse endocrine system that give rise to small intestinal NENs are endodermally derived and originate from gastrointestinal stem cells. Neuroendocrine cells and their neoplastic counterparts, secrete peptide hormones and biogenic amines. On electron microscopy, typical large neurosecretory granules and small synaptic like vesicles are found in their cytoplasm. These structures are also...
