text: Yo, check it out, I'm about to drop some knowledge,
  Talkin' 'bout carcinoids, neuroendocrine tumours in college,
  They be secreting hormones like gastrin, insulin, and ACTH,
  Liver's where they like to metastasize, that's a fact, see.
  
  But it's rare to find a primary carcinoid tumour in the liver,
  So let me tell you 'bout this case that made us shiver,
  A 51-year-old Caucasian man, symptoms all around,
  Diarrhoea, weight loss, duodenum ulcers, what's going down?
  
  Ultrasonography revealed a liver mass, oh man,
  Primary hepatic carcinoid tumour with a Zollinger Ellison plan,
  Diagnosis was made, surgery resection came into play,
  Two years later, symptoms gone, gastrin levels okay.
  
  Now, let's talk about this uncommon diagnosis, it's unique,
  Radiological and pathological features that we seek,
  Gotta rule out other primary locations, that's the key,
  Only 7 cases of hepatic carcinoids with gastrin, can you believe?
  
  So we hit up the medical literature, did a thorough review,
  To find the right tools for an accurate diagnosis, that's what we do,
  Treatment approaches, we got 'em all covered, no doubt,
  When it comes to hepatic carcinoids, we know what it's about.
  
  So there you have it, the story of a hepatic carcinoid,
  With Zollinger Ellison syndrome, a challenge we can't avoid,
  But through surgery and proper care, we made it through,
  Now we're sharing this knowledge, so it can help others too.
