Summary
We describe two female patients with B prolymphocytic leukemia, a rare blood cancer. One presented with severe symptoms and high white blood cell counts, while the other was asymptomatic. This study highlights B prolymphocytic leukemia in Chile.
Area of Science:
- Hematology
- Oncology
- Immunology
Background:
- B prolymphocytic leukemia (B-PLL) is an aggressive lymphoid malignancy.
- Understanding its clinical and laboratory spectrum is crucial for diagnosis and management.
Observation:
- Two female patients, aged in their fifth and seventh decades, were diagnosed with B-PLL.
- Clinical presentations varied from massive splenomegaly and high white blood cell counts to asymptomatic cases with low counts.
Findings:
- Flow cytometry confirmed B-cell lineage with strong surface immunoglobulin (Ig) expression and lack of T-cell markers.
- Immunoglobulin heavy-chain gene rearrangements at the DNA level validated the B-cell origin of the leukemia.
Implications:
- This report details the first documented cases of B-PLL in Chile.
- These findings contribute to the global understanding of B-PLL demographics and clinical diversity.
