Carcinoid syndrome

Dr Yuranga Weerakkody et al.

The carcinoid syndrome refers to a spectrum of symptoms which includes flushing, diarrhea, bronchospasm, pain, and right heart failure which can occur in the context of a carcinoid tumour. The symptoms result from systemic circulation of secretory substances: serotonin, histamine etc. The presence of the carcinoid syndrome often indicates hepatic metastatic disease, usually from a primary bowel carcinoid tumour.
