Template:ICD10 Guideline leukemia vs lymphoma

This template is used to make sure there are consistent instructions in the leukemia and lymphoma pages.

Lymphoma codes:

Hodgkin's lymphoma (Hodgkin's disease) Lymphoma, NOS Non-Hodgkin's lymphoma T-cell lymphoma

Template:Discussion Tina still needs to add the template call to all of these.

Leukemia vs Lymphoma

Any lymphoma may have a leukemic phase where the abnormal clonal cells appear in the circulation. Though this is sometimes referred to as a "leukemia", even by some oncologists, that is technically incorrect and ICD10 considers them to be lymphomas. This applies to essentially ALL so-called B-cell leukemias, which are actually lymphomas. It also applies to "NK-cell leukemia" which is also a lymphoma

As such, the following "leukemias" should be coded as follows: Template:DiscussAllan

• B-cell leukemia-B-cell leukemia describes several different types of lymphoid leukemia which affect B cells.
  • Types of B cell leukemia include:
    • B cell chronic lymphocytic leukemia
    • Precursor B cell lymphoblastic leukemia
    • Acute Lymphoblastic leukemia, mature B cell type
    • B cell prolymphocytic leukemia

• NK-cell leukemia-Natural killer (NK) cells are a type of lymphocyte (called large granular lymphocytes) that attacks foreign cells.
  • Aggressive NK-cell leukemia (also called aggressive NK-cell lymphoma, or ANKL), is a very rare type of NHL. The body makes large numbers of NK cells that are larger than normal. It is grouped with T-cell lymphomas.
  • There is a very rare slow-growing (indolent) type of NK-cell leukemia that has a more favorable prognosis. It is called chronic NK-cell leukemia and is treated like T-cell large granular lymphocytic leukemia.
• The most common type of lymphoid leukemia is B-cell chronic lymphocytic leukemia.
