Meaning and Definition
A constellation of symptoms caused by a carcinoid tumour secreting vasoactive substances, primarily serotonin, into the bloodstream.
The clinical presentation resulting from the systemic effects of hormones (like serotonin, bradykinin, histamine) released by neuroendocrine tumours, most commonly occurring in the gastrointestinal tract. Symptoms include flushing, diarrhoea, wheezing, and cardiac complications.

Common Mistakes When Using “carcinoid syndrome”
- Confusing 'carcinoid syndrome' with the tumour itself (e.g., 'He has a carcinoid syndrome' instead of 'He has a carcinoid tumour causing carcinoid syndrome').
- Misspelling as 'carcinoid sindrome' or 'carcinoma syndrome' (which is different).
- Using it as a countable noun (e.g., 'carcinoid syndromes') – it is typically a non-count syndrome name.
FAQ
Frequently Asked Questions
No. A carcinoid tumour is the growth itself. Carcinoid syndrome is the collection of symptoms that occur only when such a tumour, usually after spreading to the liver, releases large amounts of hormones like serotonin into the systemic circulation.
The flushing is primarily caused by the tumour's secretion of vasoactive substances, including serotonin, bradykinin, and prostaglandins, which lead to sudden dilation of blood vessels in the skin.
First-line treatment typically involves long-acting somatostatin analogues (e.g., octreotide, lanreotide) to inhibit hormone secretion. Other approaches include tumour debulking surgery, liver-directed therapies, and managing specific symptoms like diarrhoea and heart complications.
While the syndrome itself can often be effectively controlled with medication, a 'cure' usually requires complete surgical resection of the underlying tumour, which is not always possible if it has metastasised. Management is therefore often long-term and focused on control.

Learning
Memory Aids
Mnemonic
Think: CARCINOID = a type of tumour. SYNDROME = a set of symptoms. So, 'Carcinoid Syndrome' is the symptom set caused by that tumour's secretions.
Conceptual Metaphor
Not typically metaphorically conceptualised. Viewed literally as a mechanistic chain: TUMOUR -> HORMONE RELEASE -> SYSTEMIC EFFECTS -> SYMPTOMS.
