Gastric Neuroendocrine Tumor, A Rare Tumor Of Gastrointestinal Tract

Carcinoid tumors, or carcinoids, originate in hormone-producing cells of the gastrointestinal (GI) tract (i.e., esophagus, stomach, small intestine, colon), the respiratory tract (i.e., lungs, trachea, bronchi), the hepatobiliary system (i.e., pancreas, gallbladder, liver), and the reproductive glands (i.e., testes, ovaries). Carcinoids are classified as neuroendocrine tumors. They develop in peptide- and amineproducing cells, which release hormones in response to signals from the nervous system. Gastric neuroendocrine carcinoma (NEC) is an uncommon cancer of the stomach with agressive behavior and poor prognosis. They rarely cause signs and symptoms until advanced stages of the disease. Frequently, the diagnosis is made after they become symptomatic; as carcinoid syndrome. We report a case of a patient with autoimmune gastritis and a well differentiated neuroendocrine tumor of the stomach, early diagnosed and received early surgical treatment.
