Graft-versus-host disease, abbreviated as GVHD, is a rare thingy seen mostly in tertiary care centres. It is a complication of hematopoietic stem cell transplantation.

General

  • Complication of hematopoietic stem cell transplantation, i.e. bone marrow transplantation (BMT).
    • Affects skin, liver (bile ducts), gastrointestinal tract.[1][2]
  • The histology of GVHD in the intestine is the same as rejection in bowel transplantation.[3]

Clinical:

  • May present as diarrhea.
  • Main DDx (clinical): infection and certain drugs, especially mycophenolate

Microscopic

Microscopic (skin)

Features:[4]

  1. Keratinocyte apoptosis.
    • Intensely eosinophilic on H&E.
  2. Epidermotropic lymphocytic infiltrate = lymphocytes in the epidermis.
  3. Vacuolar degeneration of basal and suprabasal cells in the epidermis.

Note:

  • Apoptotic cells should not be confused with dyskeratotic cells.[5]

Grading[4]

  • Grade I: Only vacuolar changes, no apoptosis, no lymphocytes; not treated.
  • Grade II: Only scattered apoptotic cells.
  • Grade III: Focal separation/cleft formation at the dermal-epidermal junction.
  • Grade IV: Extensive necrosis with degeneration of epidermis.

Notes:

  • Same scheme applies to esophagus... it has the same structure.
  • Originally described in NEJM.[6]

Microscopic (intestine)

Features:[7]

  • Isolated epithelial cell apoptosis - key feature.
  • +/-Crypt destruction (focal or extensive).
  • +/-Loss of epithelium (denudation).

Notes:

  • Neutrophils may be present.

DDx:

  • Drug effect (mycophenolate mofetil) - cannot be distinguished from GVHD.

Grading[7]

  • Grade 1 = isolated epithelial cell apoptosis.
    • No crypt loss/destruction.
  • Grade 2 = individual crypts are lost/scatter destruction of single crypts.
  • Grade 3 = foci several adjacent crypts lost.
  • Grade 4 = large number of adjacent crypts lost/loss of epithelium.

Notes:

  • Low-grade rejection is a diagnosis that requires a careful examination, i.e. it is subtle.

Microscopic (liver)
