title: Relapsed Hodgkin's Lymphoma Presenting with Isolated Ulcerative Lesion on Base of Tongue.
abstract: BACKGROUND
  Primary extra nodal involvement of Hodgkin's lymphoma is very uncommon and previous reports of Hodgkin's lymphoma involving the base of tongue as isolated lesion in relapsed disease are few.
  
  
  METHODS
  A 79-years male patient who has diagnosed and treated for stage IV Nodular sclerosis Hodgkin lymphoma 2 years back, now presented with isolated ulcerative lesion in base of tongue which was metabolically active on positron emission tomography scan, suspicious of recurrent disease and was confirmed by routine microscopy and immunohistochemistry of tissue biopsy.
  
  
  CONCLUSIONS
  Extra nodal relapse at base of tongue was an uncommon clinical scenario in natural history of Hodgkin's lymphoma, which can present as an unexpected challenge for diagnosis and management. So we should be aware of this uncommon but unique presentation of Hodgkin's lymphoma.
