Summary
Flow cytometry (FC) is crucial for diagnosing Sézary syndrome (SS) when skin biopsies are inconclusive. This method detects aberrant T-cells, confirms clonality, and aids in staging and treatment monitoring for improved patient outcomes.
Area of Science:
- Hematology
- Oncology
- Immunology
Background:
- Sézary syndrome (SS) is a rare leukemic variant of cutaneous T-cell lymphomas.
- Diagnosis is challenging due to non-diagnostic skin biopsies, delaying treatment.
- Peripheral blood flow cytometry (FC) is vital for detecting aberrant T-cells and assessing clonality.
