Carcinoid Tumors[edit]
Carcinoid tumors are a type of neoplasm that primarily develops in the mucosa of the gastrointestinal tract. These tumors can be either benign or malignant and are often associated with an excessive secretion of Serotonin.

Characteristics[edit]
Carcinoid tumors are distinctive for their potential to produce serotonin, a neurotransmitter involved in the regulation of mood, digestion, and other bodily functions. The overproduction of serotonin by these tumors can lead to unique clinical symptoms.
Location[edit]
While carcinoid tumors can develop in any part of the gastrointestinal tract, they are most commonly found in the:
- Appendix
- Small intestine
- Rectum
Symptoms and Carcinoid Syndrome[edit]
In some cases, especially when the tumor metastasizes, it can lead to a condition known as Carcinoid syndrome. Symptoms of this syndrome include:
- Flushing
- Diarrhea
- Wheezing
- Abdominal pain
Diagnosis[edit]
Diagnosis of carcinoid tumors typically involves:
- Imaging tests such as CT scans or MRI
- Endoscopic examinations
- Biopsy and histological analysis
- Measurement of serotonin levels in the blood
Treatment[edit]
Treatment options vary depending on the location and size of the tumor, and whether it has metastasized. Common treatments include:
- Surgical removal of the tumor
- Medication to control symptoms
- Chemotherapy and radiation therapy for advanced cases
