T-cell/histiocyte-rich large B cell lymphoma (THRLBCL) is a distinct entity of aggressive lymphoma, recognized by the WHO classification as a separate entity (2008), in which few scattered neoplastic cells (usually

Phenotype stem cell origin

The postulated normal counterpart is a germinal centre B cell.
The immunophenotype of the neoplastic component in pan-B positive, BCL6+, CD15-, CD30-.


It accounts for a minority of diffuse large B-cell lymphoma (


The disease runs an aggressive course and is usually associated with poor outcome in those patients presenting at an advanced stage.


The lymph node section shows scattered large cells surrounded by many lymphocytes and histiocytes. The disease must be distinguished from nodular lymphocyte-predominant Hodgkins lymphoma, which has distinct clinical features.


Chemoimmunotherapy using anti CD20 monoclonal antibody rituximab in combination with CHOP or CHOP-like regimens is the standard of care (El Weshi et al., 2007).


A >80% overall response rate was obtained by chemoimmunotherapy, with a 5-year overall survival of approximately 50% (El Weshi et al., 2007).
