text: Yo, check it out, listen up, I got a tale to tell,
  'Bout a rare condition that's got doctors raisin' hell.
  It's called small cell neuroendocrine carcinoma,
  Of the ampulla of Vater, man, it's a real enigma.
  
  Now, this ain't your typical ampullary adenocarcinoma,
  Nah, it's a whole different drama, a rare panorama.
  And let me tell you 'bout this ampullary adenoma,
  A neoplasm that could turn into a full-on carcinoma.
  
  Now, these two don't usually come together, that's a fact,
  In the literature, their coexistence is a rare act.
  But hold up, I gotta share a case that's out of sight,
  A small cell neuroendocrine carcinoma, what a sight!
  
  It was chillin' in the ampulla of Vater, you see,
  With a villous adenoma, a crazy combo, believe me.
  We dug deep with CT scans and histopathology,
  Tryna understand this unique pathology.
  
  We broke it down, clinical, histopathological too,
  Radiological features, man, we had quite a slew.
  And as we studied, we wondered 'bout the histogenesis,
  How these two conditions came to be, it's a real genesis.
  
  So there you have it, a rap about a rare disease,
  Small cell neuroendocrine carcinoma, bringin' unease.
  With a villous adenoma, it's a wild ride,
  CT scans and histopathology as our guide.
  
  We're learnin' more each day, tryna crack the code,
  Understanding these conditions, helpin' folks on the road.
  So keep your head up, stay tuned for more to come,
  In the world of medicine, the journey's just begun.
