Hairy cell leukemia is an uncommon hematological malignancy characterized by an accumulation of abnormal B lymphocytes. [1] The incidence of hairy cell leukemia (HCL) is 0.28-0.30 cases per 100,000 people in Europe and the United States and the prevalence is 3 cases per 100,000 in Europe with a lower prevalence in Asia, Africa and the Middle East.
The 5-year survival rate for children with leukemia is 83.6% in the USA. This means that 83.6% of children diagnosed with leukemia live for 5 years or more after their diagnosis. This is greatly improved from a 5-year survival rate of 36.5% in 1975. The improvement is largely attributed to advances in therapy, particularly therapy for ALL.
Five-year survival rate was 67% in the United States in the period from 2014 to 2020. [4] In children under 15 in first-world countries, the five-year survival rate is greater than 60% or even 90%, depending on the type of leukemia. For infants (those diagnosed under the age of 1), the survival rate is around 40%.

CLL has also been reported to convert into other more aggressive diseases such as lymphoblastic lymphoma, hairy cell leukemia, high grade T cell lymphomas, [24] acute myeloid leukemia, [25] lung cancer, brain cancer, melanoma of the eye or skin, [26] [27] salivary gland tumors, and Kaposi's sarcomas. [28]
The five-year survival rate in the United States is 88.4%. [ 14 ] FL is the most prevalent form of indolent lymphoma, accounting for 70% of indolent cases and 20–30% of all non-Hodgkin lymphoma cases, with a yearly incidence of 1.6 to 3.1 per 100,000.
The T cell variations are usually caused by the prolonged use of T cell suppressant drugs, such as sirolimus, tacrolimus, or ciclosporin. [2] The Epstein-Barr virus , which infects >90% of the world population, is also a common cause of these disorders, being responsible for a wide range of non-malignant, pre-malignant, and malignant Epstein ...
Splenic B-cell lymphoma/leukemia unclassifiable: The rare reports on this lymphoma find the monoclonal B cells to be CD19+, CD20+ (bright, CD23+, CD11+, CD25−, CD103−, CD72+, and annexin A1−. [18] These cells, similar to the monoclonal cells in Hairy cell leukemia, [19] may have the V600E mutation in the BRAF gene. Patients with this ...
