Post-transplant lymphoproliferative disorder, vbbreviated PTLD, is something afflicts people that had transplants (solid organ and bone marrow). It is essentially a type of B-cell lymphoma.

General

  • Rare.
  • B cell neoplasm associated with EBV.[1][2]
    • Develop from a latent EBV infection - which may be detectable by the presence of "passenger cells" = scattered EBER positive lymphocytes.[3]
  • Commonly in the GI tract as it gets the most immunosuppression; immunosuppressives are taken orally -- not cleaned by the liver prior to reaching the GI tract.

Microscopic

Features:

  • Similar to large cell lymphomas:
    • Large lymphoid cells with a diameter ~2x a resting lymphocyte.
    • Nucleoli.

IHC

  • B cell markers +ve
  • EBER +ve -- diffuse.
