Lymphoid leukemia

Lymphoid leukemia (or lymphocytic leukemia) is a type of leukemia affecting circulating cells of lymphoid origin. This is in contrast to lymphoma, which is a solid tumor of lymphoid cells.cite book |author=Parham, Peter |title=The immune system |publisher=Garland Science |location=New York |year=2005 |pages=414 |isbn=0-8153-4093-1 |oclc= |doi= |accessdate=]

Classification

Historically, they have been most commonly divided by the stage of maturation at which the clonal (neoplastic) lymphoid population stopped maturing:
* Acute lymphoblastic leukemia
* Chronic lymphocytic leukemia

However, the influential WHO Classification (published in 2001) emphasized a greater emphasis on cell lineage. To this end, lymphoid leukemias can also be divided by the type of cells affected:
* T-cell leukemia
* B-cell leukemia
