Midgut neuroendocrine tumors (MNETs) are rare tumors that arise in the jejunum, ileum, and proximal colon. Patients tend to present late, after a long history of vague nonspecific symptoms, and disseminated metastases are often discovered at presentation.

Midgut carcinoids originating in the small intestine are the most common cause of the carcinoid syndrome. These tumours typically progress slowly and have an extended disease course, and although they often present with metastases at diagnosis, surgical treatment has become increasingly important for their management.

Midgut carcinoids originating in the small intestine are the most common cause of the carcinoid syndrome.

In addition to serotonin several other biologically active substances such as kallikrein, histamine, prostaglandins, adrenocorticotropic hormone, gastrin, calcitonin, and growth hormone among others are secreted. As compared to carcinoids elsewhere, midgut carcinoids tend to produce carcinoid syndrome Neuroendocrine tumors (NETs) are neoplasms that arise from cells of the endocrine and nervous systems.They most commonly occur in the intestine, where they are often called carcinoid tumors, but they are also found in the pancreas, lung and the rest of the body.. Although there are many kinds of NETs, they are treated as a group of tissue because the cells of these neoplasms share common In sporadic midgut carcinoids, a high frequency of deletions on chromosome 18 is described .
