Sezary Syndrome (SS) Overview

Sezary Syndrome (SS) is a type of cutaneous T-cell lymphoma, a group of disorders characterized by transforming T-cells into cancerous cells and their effect on the skin. A small percentage of SS cases have been associated with human T-lymphotropic viruses type 1 and 2 (HTLV-I/II). Although the exact cause of SS is unknown, chromosomal anomalies, particularly rearrangements in the 6q23-27 region, leading to changes in the MYB proto-oncogene and the IL22RA2 gene, have been implicated. SS is more common in men and usually presents in the fifth decade of life. Patients typically experience rapid progression of symptoms, which include scaling erythroderma, leonine facies, severe pruritus, alopecia, ectropium, mild palmoplantar keratoderma, and nail onychodystrophy. Lymphadenopathy and hepatosplenomegaly may also be present, along with chills, fatigue, and general discomfort. Differential diagnoses for SS include mycosis fungoides, psoriasis, pityriasis rubra pilaris, dermatitis, hypereosinophilic syndrome, adult T-cell leukemia, and primary skin disorders such as scabies, drug eruption, and graft-versus-host disease. Prognostic factors for SS include skin classification, disease stage, elevated LDH levels, advanced age and comorbidities, male sex, race, peripheral eosinophilia, large cell transformation, and folliculotropic MF. These factors have been used in validated prognostic indices such as the CTCL Severity Index (CTCL-SI), the Cutaneous Lymphoma International Prognostic Index (CLIPi), and the CLIC Prognostic Index.
