Untreated hairy cell leukemia is characterized by splenomegaly, varying degrees of leukopenia (occasionally leukocytosis) and/or pancytopenia, and bone marrow infiltration by an atypical cell with prominent cytoplasmic projections (i.e., hairy cells). Clear splenomegaly is a clue that hairy cell is in the differential, among other things as well. The replication of these white blood cells becomes excessive, and the aberrant cells start infiltrating in the bone marrow, causing alterations.

There is an increased chance of splenic rupture due to trauma. Hairy cell leukemia is a rare, slow-growing cancer of the blood in which the bone marrow makes too many B cells (lymphocytes), a type of white blood cell that fights infection. Most people have symptoms arising from an enlarged spleen (such as fullness or discomfort in the abdomen) or symptoms arising from reduced blood counts (abnormal bleeding/bruising/clotting, or infection). Hairy cell leukemia is a rare, chronic B cell lymphoproliferative disorder, more commonly diagnosed in men than in women, and typically arising in the middle decades of life.
