Carcinoid syndrome is the pattern of symptoms that typically are exhibited by people with carcinoid tumors. The symptoms include bright red facial flushing, diarrhea, and occasionally wheezing. A specific type of heart valve damage can occur, as well as other cardiac problems. Carcinoid tumors secrete excessive amounts of the hormone serotonin. Surgery with complete removal of the tumor tissue is the ideal treatment. It can result in a permanent cure if it is possible to remove the tumor entirely.
