Carcinoid syndrome pathophysiology

Location
Carcinoid tumours are the most common malignant tumour of the appendix, but they are most commonly associated with the small intestine, and they can also be found in the rectum and stomach. They are known to grow in the liver, but this finding is usually a manifestation of metastatic disease from a primary carcinoid occurring elsewhere in the body. They have a very slow growth rate compared to most malignant tumours. From Dr. Vinoth
