HHV-8+ EBV+ multicentric plasmablastic microlymphoma

Associations

- human immunodeficiency virus (HIV)

Synopsis

- fever
- generalized lymphadenopathy
- splenomegaly
- multicentric Castleman disease (MCD) background
- prominent proliferation of HHV-8+, EBV+, CD20, CD138, MUM1+, lambda dim+, Ig heavy chain plasmablasts and immunoblasts replacing some follicles

- spleen

  • replacement of occasional white pulp by the HHV-8+ EBV+ large lymphoid cells

- bone marrow

  • extensive hemophagocytosis
  • hemophagocytic syndrome

- MCD-associated plasmablastic lymphoproliferative disorder, with pathologic features intermediate between HHV-8+ plasmablastic microlymphoma, and HHV-8+ germinotropic lymphoproliferative disorder.
