Carcinoid syndrome refers to a spectrum of symptoms that result from excessive hormone (mainly serotonin) secretion.
Occurs equally between the sexes, most commonly in the 40-70 year age group 3.
Diarrhea is the most common and earliest symptom but others include flushing, right heart failure, pain and bronchospasm 4.
The presence of the carcinoid syndrome often indicates hepatic metastatic disease, usually from a primary bowel carcinoid tumor.
