Overview
Laboratory findings consistent with the diagnosis of mast cell leukemia include abnormal complete blood count, biochemistry, and immunohistochemistry.
Mast cell leukemia laboratory findings
- Laboratory findings consistent with the diagnosis of mast cell leukemia include abnormal complete blood count, biochemistry, and immunohistochemistry.[1][2]
- Patients with mast cell leukemia have more than 20% mast cells in bone marrow aspirates.[3]
Complete Blood Count
On complete blood count, characteristic findings of mast cell leukemia include:[1][2]
- Bicytopenia
- Anemia
- Thrombocytopenia
- Leukopenia
- Neutropenia
Biochemistry
Total serum tryptase level is elevated in mast cell leukemia.[4]
Immunohistochemistry
On immunohistochemistry, characteristic findings of mast cell leukemia include:[1][2]
- Leukemic mast cells strongly express:[2]
- Abnormal mast cells ususally express:[2]
