Overview
Sézary syndrome is a leukemic variant of cutaneous T-cell lymphoma characterized by the presence of malignant T cells in the skin and peripheral blood, often presenting with generalized erythroderma and atypical lymphocytes 12.Diagnosis
Presence of atypical cerebriform nuclei in peripheral blood lymphocytes
Skin biopsy showing epidermotropism of atypical T cells
Elevated CD4+ T-cell count with aberrant phenotypes
Histopathological examination of lymph nodes may reveal infiltration by atypical lymphocytes 1Management
Discontinue photochemotherapy (e.g., PUVA) if skin lesions are exacerbated 1
Consider systemic therapies such as retinoids, interferon-alfa, or newer agents like histone deacetylase inhibitors (specific dosing not detailed in abstracts)
Supportive care including moisturizers, emollients, and management of pruritus 1Special Populations
Photosensitivity: Patients with photosensitivity may require heightened sun protection and avoidance of triggering phototherapies 2
Elderly: No specific management differences noted, but careful monitoring for comorbidities is advised 2Key Recommendations
Cease photochemotherapy if skin lesions are exacerbated during treatment in patients with Sézary syndrome (Evidence: Moderate) 1
Monitor for photosensitivity and adjust sun protection strategies accordingly (Evidence: Weak) 2
Consider systemic immunomodulatory therapies for managing Sézary syndrome, though specific dosing recommendations are not detailed in current abstracts (Evidence: Expert opinion) 12References
