carcinoid tumor
Also known as neuroendocrine neoplasm G1, carcinoid, NET G1, neuroendocrine tumor G1, carcinoid tumors, carcinoid tumour
A carcinoid (also carcinoid tumor) is a slow-growing type of neuroendocrine tumor originating in the cells of the neuroendocrine system. In some cases, metastasis may occur. Carcinoid tumors of the midgut (jejunum, ileum, appendix, and cecum) are associated with carcinoid syndrome.

A carcinoid (also carcinoid tumor) is a slow-growing type of neuroendocrine tumor originating in the cells of the neuroendocrine system. In some cases, metastasis may occur. Carcinoid tumors of the midgut (jejunum, ileum, appendix, and cecum) are associated with carcinoid syndrome.
Sometimes, carcinoids cause paraneoplastic syndromes, which involve discharge of serotonin and other vasoactive substances from well-differentiated carcinoids. A neuroendocrine paraneoplastic syndrome involves neoplastic secretion of functional peptides, hormones, cytokines, growth factors, and/or immune cross-reactivity between tumor tissues and normal host tissues, resulting in a syndrome of clinical signs and symptoms.
