The WHO (World Health Organization) Classification of Lymphoid Neoplasms is the latest and greatest classification. It is the one to which you should refer in the future when you get a patient who has lymphoma or leukemia. It's pretty much the same thing as the REAL classification, with a few minor additions. In our course, we will only be discussing the major types of NHL (these are linked to their appropriate pages below).

B-cell neoplasms

Precursor B-cell neoplasm
  Precursor B-lymphoblastic leukemia/lymphoma

Mature (peripheral) B-cell neoplasms
  B-cell chronic lymphocytic leukemia /small lymphocytic lymphoma
