Hairy cell leukemia (HCL) is a rare, slow-growing cancer of the blood in which the bone marrow produces an excessive number of B cells (a type of white blood cell) that appear "hairy" under a microscope. These abnormal cells accumulate in the bone marrow, spleen, and blood, interfering with normal blood cell production and function.
Symptoms[edit]
Common symptoms of hairy cell leukemia include:
- Fatigue
- Recurrent infections
- Easy bruising or bleeding
- Weight loss
- Splenomegaly (enlarged spleen)
Complications[edit]
Complications of hairy cell leukemia can include:
- Anemia (low red blood cell count)
- Thrombocytopenia (low platelet count)
- Increased risk of infections due to low white blood cell count
Diagnosis[edit]
Hairy cell leukemia is typically diagnosed through:
- Blood tests showing abnormal cells
- Bone marrow biopsy confirming the presence of hairy cells
Differential Diagnosis[edit]
Conditions that may be considered in the differential diagnosis include:
Treatment[edit]
Treatment options for hairy cell leukemia include:
- Chemotherapy with drugs such as cladribine or pentostatin
- Immunotherapy with agents like rituximab
- Splenectomy (surgical removal of the spleen) in certain cases
Prognosis[edit]
The prognosis for individuals with hairy cell leukemia is generally good, especially with appropriate treatment. Many patients achieve long-term remission.
Epidemiology[edit]
Hairy cell leukemia is a rare condition, most commonly diagnosed in middle-aged adults, with a higher prevalence in males.
