Overview
Sezary syndrome is a leukemic variant of cutaneous T-cell lymphoma characterized by the presence of Sezary cells in the peripheral blood, often accompanied by erythematous dermatitis and lymphadenopathy 1.Diagnosis
Presence of Sezary cells in peripheral blood with characteristic features such as folded nuclei and cytoplasmic projections 1.
Atypical lymphocytes of T-phenotype identified through flow cytometry or immunophenotyping 1.
Skin biopsy showing typical cutaneous infiltration by malignant T-cells 1.
Bone marrow involvement may be present and should be evaluated 1.
Histopathological examination highlighting cerebriform nuclei and ultrastructural features 1.Management
First-line treatment typically involves chemotherapy regimens such as CHOP (Cyclophosphamide, Doxorubicin, Vincristine, Prednisone) 1.
Immunotherapy with agents like interferon-alfa may be considered for selected patients 1.
Targeted therapies such as retinoids (e.g., bexarotene) are used in refractory cases 1.
Supportive care including topical corticosteroids and emollients for skin symptoms 1.Special Populations
No specific data provided regarding pregnancy, pediatrics, or elderly populations in the given abstracts 1.
Comorbidities may influence treatment selection but specific recommendations are not detailed 1.Key Recommendations
Confirm diagnosis through identification of Sezary cells in peripheral blood and characteristic ultrastructural features (Evidence: Weak) 1.
Initiate first-line treatment with CHOP chemotherapy regimen for systemic involvement (Evidence: Expert opinion) 1.
Consider immunotherapy with interferon-alfa for patients not responding to initial chemotherapy (Evidence: Weak) 1.References
