Overview

Classification

Based on the clinical presentation, intravascular large B-cell lymphoma may be classified into either Western variant or Asian variant.

Intravascular large B-cell lymphoma classification
Name Description
Western variant
  • Western variant characterized by symptoms related to the main organ involved, predominantly neurological or cutaneous
Asian variant
  • Asian variant in which the patients present with multi-organ failure, hepatosplenomegaly, pancytopenia, and hemophagocytic syndrome.
  • 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.

Pathophysiology

Microscopic Pathology

Causes

There are no established causes for intravascular large B-cell lymphoma.

Differentiating type page name here from other Diseases

Intravascular large B-cell lymphoma must be differentiated from other diseases such as:

Risk Factors

There are no established risk factors for intravascular large B-cell lymphoma.

Screening

According to the the U.S. Preventive Service Task Force (USPSTF), there is insufficient evidence to recommend routine screening for intravascular large B-cell lymphoma.[2]

Natural History, Complications and Prognosis

  • People with this type of lymphoma can also develop a very serious condition where certain parts of the immune system are activated (hemophagocytic syndrome).[1]
