Overview
Diagnosis of hairy cell leukemia is based on characteristic morphologic findings together with immunophenotypic and molecular studies.
Diagnostic Study of Choice
Study of choice
Peripheral blood smear:
Diagnosis of hairy cell leukemia requires immunophenotypic confirmation. [1]
Peripheral blood smear examination may provide an initial diagnostic clue.[2]
The following result of peripheral blood smears is confirmatory of hairy cell leukemia[2]:
- Oval nuclei and abundant clear cytoplasm with "hairy" projections
- "Fried egg" appearance
- Loose chromatin
- Mast cells numbers elevate
- Extravasated red cells are positive in peripheral blood smear of hairy cell leukemia patients
