Overview
In T-cell prolymphocytic leukemia, the peripheral blood smear demonstrates the predominance of lymphocytes and high lymphocyte count (> 100 x 109/L).
Laboratory Findings
- Laboratory findings consistent with the diagnosis of T-cell prolymphocytic leukemia, include:[1]
- High lymphocyte count (> 100 x 109/L)
- Anemia
- Thrombocytopenia
- Negative human T lymphotropic virus (HTLV) serology
- Peripheral Blood Smear demonstrated predominance of lymphocytes:
- Typical variant:
- Medium-sized lymphocytes
- Condensed chromatin and a visible nucleolus
- Round nucleus
- Slightly basophilic cytoplasm
- Cytoplasmic protrusion
- Small cell variant
- Small tumor cells with condensed chromatin
- Small nucleolus visible by electron microscopy
- Cerebriform (Sézary cell-like) variant
- Irregular nuclear outline
- Similar to cerebriform nucleus of Sézary cells seen in mycosis fungoides
- Typical variant:
