Abstractor Notes

(This code is effective for cases diagnosed 2010 and later. For cases diagnosed prior to 2010, see code 9680/3.)

1. Western form characterized by symptoms related to the main organ involved, predominantly neurological or cutaneous

2. Asian variant in which the patients present with multi-organ failure, hepatosplenomegaly, pancytopenia, and hemophagocytic syndrome. B symptoms very common in both types of presentations. This is an aggressive lymphoma which responds poorly to chemotherapy. The poor prognosis reflects in part frequent delays in diagnosis because of a lack of detectable tumor masses.

An isolated cutaneous variant has been identified invariably in Western females. It is characterized by limitation of tumor to the skin and has a better prognosis.

Diagnostic Confirmation

This histology can be determined by positive histology (including peripheral blood) with or without genetics and/or immunophenotyping. Review the Definitive Diagnostic Methods, Immunophenotyping and Genetics Data sections below, and the instructions in the Hematopoietic Manual for further guidance on assigning Diagnostic confirmation.

Definition

Intravascular large B-cell lymphoma is a rare type of extranodal large B-cell lymphoma characterized by the selective growth of lymphoma cells within the lumina of vessels, in particular capillaries, and with the exception of larger arteries and veins.

Definitive Diagnostic Methods

Genetic testing
Immunophenotyping

Genetics Data

Immunoglobulin genes are clonally rearranged

Immunophenotyping

CD5 and CD10+ (expression/positive)
CD10- cases are IRF4/MUM1+ (expression/positive)
CD29 (inegrin beta-1) lacking
CD54 (ICAM1) adhesion beta-molecules lacking

Treatments

Chemotherapy
