Argentaffinoma is characterized by excess excretion of_____________?
Correct answer: C. 5- Hydroxy indole acetate
- A. Phenyl lactate
- B. 3- Hydroxy phenyl pyruvate
- C. 5- Hydroxy indole acetate
- D. Phenyl acetate
Explanation
Argentaffinoma, commonly associated with a serotonin-secreting carcinoid tumour, produces excess serotonin that is metabolised to 5-hydroxyindoleacetic acid (5-HIAA). Increased urinary 5-HIAA is therefore a useful marker.
