Definition / general
  • Aggressive
  • Usually presents with splenomegaly and advanced disease
  • Often with bone marrow involvement; may have marked lymphocytosis mimicking prolymphocytic leukemia
  • Blastoid variant may develop result in splenic rupture
  • Other variants include pleomorphic, small cell and marginal zone-like
  • Postulated normal counterpart is nave pregerminal center B cell of inner mantle zone
Clinical features
Case reports
Microscopic (histologic) description
  • Confluent tumor nodules in white pulp or enlarged lymphocytic coronas surrounding germinal centers
  • Often involvement of red pulp
  • Small cells with irregular, often indented, hyperchromatic nuclei
  • No proliferation centers, no prolymphocytes
  • May have marginal zone-like differentiation, with more abundant, pale staining cytoplasm
