Physical Examination
• Abdominal mass and enlarged liver.
• Prominent skin veins (telangiectasis).
• Signs of the carcinoid syndrome—heart murmur, wheezing on expiration and flushing of the skin.
Blood and Other Tests
• Metastatic carcinoid tumors may be diagnosed by elevated levels of 24-hour urinary 5-hydroxyindolacetic
acid (5HIAA), a metabolic product of the serotonin produced by the tumor. False positive 5-HIAA tests can
be caused by foods such as bananas, avocados and pineapple and by certain drugs. The laboratory should
provide a complete list of foods to be avoided during urine collection.
Imaging
• X-rays of the chest and gastrointestinal tract (small bowel and barium enema).
• CT or MRI scan of the abdomen to detect liver metastases.
Endoscopy and Biopsy
• Liver biopsy may be required.
