What is Primary Splenic Red Pulp Diffuse Large B-Cell Lymphoma?

Surreal illustration of splenic red pulp lymphoma research.

Primary splenic red pulp diffuse large B-cell lymphoma with anaplastic features is an extremely rare subtype of diffuse large B-cell lymphoma (DLBCL) that primarily affects the red pulp of the spleen. Unlike more common forms of DLBCL that typically involve the white pulp and form distinct nodules, this rare variant is characterized by a diffuse infiltration of neoplastic cells throughout the red pulp, the region of the spleen responsible for filtering blood and removing damaged or aged blood cells.

This lymphoma is characterized by distinct pathological and clinical features that differentiate it from other types of DLBCL. The neoplastic cells in this lymphoma are typically large and pleomorphic, displaying a range of unusual shapes and sizes. These cells often exhibit anaplastic features, meaning they have lost some of the normal characteristics of mature B cells and have become more primitive and undifferentiated.

  • Diffuse Red Pulp Involvement: The lymphoma cells infiltrate the red pulp of the spleen, replacing the normal splenic architecture.
  • Anaplastic Features: The neoplastic cells display unusual shapes and sizes, with large, irregular nuclei and prominent nucleoli.
  • Hemophagocytosis: The presence of hemophagocytosis, where immune cells engulf and destroy other blood cells, is a common feature.
  • Extramedullary Hematopoiesis: The spleen may exhibit extramedullary hematopoiesis, the production of blood cells outside the bone marrow.

How this rare presentation fits existing classifications

The paper described primary red-pulp DLBCL as extremely rare and absent from the 2008 WHO classification; it noted red-pulp involvement, hemophagocytosis, and splenic extramedullary blood formation among its characteristic features. It also described frequent liver and bone-marrow involvement and absence of systemic lymphadenopathy as part of that proposed pattern, not as findings established for every case.[1]

A later WHO-HAEM5 account lists several members of the splenic B-cell lymphoma and leukaemia family, including splenic diffuse red-pulp small B-cell lymphoma and splenic marginal zone lymphoma. That classification context names related categories but does not resolve the status of the large-cell red-pulp presentation in this case.[1] [2]

Questions the case leaves open

  • Does this red-pulp large B-cell lymphoma represent a distinct disease entity, or can it arise through transformation from a low-grade lymphoma?[1]
