Rare lymphocytic leukemias

The World Health Organization (WHO) uses the criteria below to classify a cancer that starts in lymphocytes as a lymphoma, a lymphocytic leukemia or a leukemia/lymphoma. They differ in where the abnormal lymphocytes are found.

  • If the abnormal lymphocytes are found mainly in the blood or bone marrow, it is considered leukemia.
  • If tumours develop in the lymph nodes or other organs, it is considered a lymphoma.
  • If the disease is found in the blood or bone marrow and as a tumour, it is considered a leukemia/lymphoma.
