text: Yo, check it out, let me break it down for ya,
  Idiopathic plasmacytic lymphadenopathy, IPL for short,
  Same as multicentric Castleman's disease, MCD, out in the West,
  Clinically, they both got multicentric lymphadenopathy,
  Hypergammaglobulinemia, high levels causin' quite the frenzy.
  
  Elevated erythrocyte sedimentation rate, IL-6 in the blood,
  Bone marrow plasmacytosis and lab results showin' floods,
  Anemia and positive autoantibodies, yeah they're in the mix,
  But IPL got a better 5-year survival rate, that's the fix.
  
  No Kaposi's sarcoma or B-cell lymphoma, that's a win,
  In the present 16 cases, they didn't let those demons in,
  Histologically, interfollicular area got mature plasma cells,
  Both IPL and MCD, they got that goin' well.
  
  In MCD, lymphoid follicles got germinal centers vascular and clear,
  But IPL, them follicles hyperplastic, showin' no fear,
  Immunostaining reveals a normal follicular dendritic cell network,
  No herpes virus-8-positive cells, that's the perk.
  
  Overall, clinicopathologic and immunohistochemical display,
  Our 16 cases suggest IPL stands out in its own way,
  It's distinct from MCD in the Western world,
  That's the rap on IPL, now the knowledge unfurled.
