Types of Leukemia – List of Common and Rare Leukemia Types

Hairy cell leukemia (HCL)

It is a type of leukemia affecting lymphocyte creation and maturation, especially B cells. It is a type of blood cancer that progresses very slowly and can be considered a subtype of chronic lymphocytic leukemia. One of the characteristic features of hairy cell leukemia is the form adopted by the aberrant B cells. They display a series of cytoplasmic prolongation similar to villi or hairs, which is why they are called hairy cells.

This disease is more common in older adults and symptoms include recurrent infections, unexplained fever, muscle weakness and chronic fatigue, unexplained and unexpected weight loss, swollen lymph nodes, and easy bruising.
