text: Yo, check it out, let me break it down for you,
  Vasculitis, inflammation that's immune-mediated, true,
  Messin' up the vessel walls, structural damage, it's a shame,
  When your immune system triggers leukocytoclastic game.
  
  But hold up, we've been focused on just one side,
  Lymphocyte-mediated vasculitis, let it ride,
  We gotta redefine our understanding, no doubt,
  Breakin' stereotypes, let's figure this out.
  
  Lymphocytic vasculitis, it's a different breed,
  Not just necrosis and hemorrhage, take heed,
  Autoimmune skin diseases, like graft vs host,
  Share similarities, yeah, they come close.
  
  Inflammation caused by lymphocytes, a whole new class,
  Separate from the angiodestruction that's known to pass,
  Lymphocytic endovasculitis, lichenoid vasculitis too,
  Even granulomatous vasculitis, we're breakin' through.
  
  But to prove it, we need new techniques in our arsenal,
  Molecular pathology, go beyond the usual,
  Analyze the immunological events, don't be confined,
  Push past the limitations, expand our mind.
  
  So remember, vasculitides can be lymphocytic,
  It's time to break free from the past, it's so prolific,
  With advancements in pathology, we'll get the scoop,
  Lymphocyte-mediated vasculitis, a whole new group.
