Enteropathy-associated T-cell lymphoma, abbreviated EATL, is an uncommon type of lymphoma associated with celiac disease.

It is also known as enteropathy-type T-cell lymphoma, abbreviated ETTL.

General

  • T cell lymphoma classically due to celiac sprue.
  • Historically subdivided into type I and type II.[1]
    • Pleomorphic anaplastic (type I) associated with celiac sprue.[2] - this is now referred to as EATL since the 2017 revision of the WHO blue book 4th edition.
    • Monomorphic (type II) not associated with celiac sprue - this is separate entity known as monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL); it is no longer referred to as EATL as it is not associated with an enteropathy.
  • Poor prognosis.[3]
    • Five-year survival as low as 20%.[4]

Presentations - may include:

Treatment:

  • Chemotherapy.[6]
  • Autologous stem cell transplantation.[7]

Gross

Features:[8]

  • Typically manifest as ulcers, fissures or plaques. †

Notes:

  • † B-cell lymphomas are typically raised nodules.[8]

Microscopic

Features:[9]

  • Abundant large or medium-sized lymphoid cells in the mucosa and submucosa.
    • Large-sized cells ~ 2x RBC diameter = type 1.
    • Medium sized cells ~ 1.5x RBC diameter = type 2.
  • Intestinal epithelium usually preserved.

  • CD8 -ve/+ve.
  • CD56 +ve.
