Classification

  • Type I enteropathy-associated T-cell lymphoma
  • Type II enteropathy-associated T-cell lymphoma
Enteropathy-associated T-cell lymphoma classification[1][3][4]
Name Description
Classical enteropathy-associated T-cell lymphoma (Type I Enteropathy-associated T-cell lymphoma)
  • Covers 80-90% of all enteropathy-associated T-cell lymphoma cases.
  • Is usually associated with refractory celiac disease that is sometimes accompanied by intestinal ulceration (ulcerative jejunitis)
  • Most show adult onset disease or are diagnosed as having celiac disease in the same clinical episode in which the lymphoma is diagnosed.
  • Frequently has large-cell or pleomorphic cytology.
  • Seldom expresses CD8 and CD56.
Monomorphic enteropathy-associated T-cell lymphoma (Type II enteropathy-associated T-cell lymphoma)
  • Encountered in Asia and other regions where celiac disease is rare.
  • Is sporadic, seldom associated with celiac disease.
  • Covers 10-20% of all enteropathy-associated T-cell lymphoma cases.
  • Is characterized by monomorphic cytology.
  • Frequent expression of CD8 and CD56.
  • The tumor forms an ulcerating mucosal mass that invades the wall of the intestine.
  • Poor prognosis, death occurs from abdominal complications such as small bowel obstruction, perforation.
