Enteropathy type T-cell lymphomas (ETL) are common gastrointestinal cancers. Two distinct ETL types exist, differing in cell appearance, disease association, and genetic markers, impacting diagnosis and treatment.

Area of Science:

  • Gastroenterology
  • Hematology
  • Oncology

Context:

  • Enteropathy type T-cell lymphomas (ETL) are the most common T-cell lymphomas in the gastrointestinal tract.
  • These neoplasms often present with malabsorption symptoms and spontaneous bowel perforation.

Purpose:

  • To distinguish between the two main types of ETL based on morphology, immunophenotype, and pathogenesis.
  • To highlight the genetic characteristics, specifically chromosomal gains of 9q33-q34, common in ETL.

Summary:

  • 80% of ETL cases are associated with celiac disease, displaying pleomorphic cytomorphology and rare CD8/CD56 expression.
  • The remaining 20% of ETL cases show monomorphic morphology, frequent CD8/CD56 expression, and rare celiac disease association.

Impact:

  • Improved diagnostic accuracy for ETL subtypes.
  • Potential for targeted therapies based on distinct ETL characteristics.
  • Enhanced understanding of ETL pathogenesis and genetic underpinnings.
