Clinics and Pathology


Immunoblastic lymphoma is one of 3 morphologic variants of diffuse large B cell lymphoma (DLBCL). The other 2 variants are centroblastic lymphoma and anaplastic B-cell lymphoma.
The disease is not recognized as a separate entity in the WHO classification (2008).

Phenotype stem cell origin

The postulated normal counterpart is a germinal centre B cell or an activated post germinal centre B cell.


It accounts for approximately 1/4 of DLBCL.


The disease runs an aggressive course, as all DLBCL.


The lymph node section shows an overwhelming infiltrate (>90%) by medium-to-large size cells with centrally located nucleolus and fairly abundant basophilic cytoplasm.


Chemoimmunotherapy using anti CD20 monoclonal antibody rituximab in combination with CHOP or CHOP-like regimens is the standard of care.


Chemoimmunotherapy may cure 40-60% of the cases depending on age and risk factors.
