SUMMARY

This case report outlines the diagnosis and management of T-cell prolymphocytic leukaemia (T-PLL) in a 78-year-old asymptomatic woman. The leukaemia rapidly progressed within five months, leading to a hyperleukocytosis of 305 × 109/L and thrombopenia suggestive for bone marrow involvement. Diagnostic assessments included peripheral blood analysis, immunophenotyping, cytogenetics and molecular analysis according to the unified diagnostic criteria of the T-PLL International Study Group (T-PLL-ISG). Bendamustine treatment was initiated resulting in a significant decrease in leucocytosis. In the past nine months, the patient has received six cycles of bendamustine and has remained asymptomatic to date.
