Lymphomatoid granulomatosis (Liebow)
Clinical signs
  • rare multisystemic disease affecting lungs, skin and nervous system
  • exact nature is unclear
  • skin is involved in more than 50% of the patients
  • scattered nodules, eroded and crusted lesions, recurrent skin ulcerations, facial edema, papules and folliculitis like eruptions
  • bad prognosis
Etiology

Caused by EBV infection.

Histology

Polymorphous nodular skin lesions with dense angiocentric and angiodestructive infiltrate in the dermis and subcutaneous tissue. No epidermal involvement. Almost exclusive vasocentricity of the lesions.

Immunophenotype and genetic features:

  • T helper (memory) cells (CD2+, CD3+, CD4+, CD5+, CD7+, CD45RO+)
  • variable expression of activation antigenes (CD25-, CD38+, CD71+, HLA-DR+)
  • Ki67 positive in 20% of nuclei
  • virus Epstein-Barr is positive in some cells of the infiltrate
