Definition: Lymphomatoid granulomatosis is a rare lesional syndrome associated with Epstein-Barr virus EBV-associated B-cell LPD or peripheral T-cell lymphoma.

Lymphomatoid granulomatosis is an angio-destructive lymphoproliferative disorder (LPD) with prominent pulmonary involvement.

Most LYG are an Epstein-Barr virus (EBV)-associated B-cell LPD with large numbers of background reactive T lymphocytes (T cell-rich B cell lymphoma) and can be considered as a rare angiocentric and angiodestructive form of EBV-associated B-cell LPD.

Some are associated with peripheral T-cell lymphoma (#7573693#, #11085664#).

Synopsis

- angiocentric immunoproliferative lesion

  • angiocentric or angiodestructive lesions with lymphocytic infiltrates (angioinvasion)
  • marked angiocentric lymphohistiocytic infiltrate, composed predominantly of CD4-positive T-cells, with angiodestruction and necrosis

- zonal necrosis
- atypical tumoral cells

  • associated EBV-associated peripheral B-cell lymphoma
  • associated peripheral T-cell lymphoma (#11085664#)
