Ten per cent (10%) [50] or less of carcinoids, primarily some midgut carcinoids, secrete excessive levels of a range of hormones, most notably serotonin (5-HT) or substance P, [51] causing a constellation of symptoms called carcinoid syndrome: [citation needed] flushing; diarrhea; asthma or wheezing; congestive heart failure (CHF) abdominal ...

The new 2019 WHO classification and grading criteria for neuroendocrine tumors of the digestive system grades all the neuroendocrine tumors into three grades, based on their degree of cellular differentiation (from well-differentiated NET grade (G)1 to G3, and poorly-differentiated neuroendokrina cancer, NEC G3), morphology, mitotic rate and Ki ...
Carcinoid syndrome is a paraneoplastic syndrome comprising the signs and symptoms that occur secondary to neuroendocrine tumors (formerly known as carcinoid tumors).

Gastrinoma is the second most common functional pancreatic neuroendocrine tumor (pNET), with a yearly incidence of approximately 0.5 to 21.5 cases per a million of people worldwide. [5] Gastrinomas are located predominantly in the duodenum (70%) and pancreas (25%). [ 20 ]
Symptoms include abdominal pain and diarrhea. The syndrome is caused by a gastrinoma, a neuroendocrine tumor that secretes a hormone called gastrin.
