Background Sézary syndrome is a cutaneous T-cell lymphoma characterized by erythroderma and leukemic involvement. Objective We sought to define the clinical, biologic, and histopathologic features of Sézary syndrome without erythroderma. Methods Features of patients with Sézary syndrome and normal-appearing skin or stage-T1 patches, fulfilling Sézary syndrome hematologic criteria and with histologically documented disease in normal-appearing skin were collected. Expression of Sézary syndrome molecular biomarkers in peripheral blood and skin lymphocytes were studied. Results Five women and 1 man (median age: 71 years) were all referred for generalized pruritus. Four had no specific lesions; 2 had T1-stage patches. Histologic examination of normal-appearing skin from all patients showed lesions compatible with Sézary syndrome. Peripheral blood lymphocytes from 3 of 4 patients tested strongly expressed PLS3, Twist-1, and KIR3DL2. All normal-appearing skin biopsy specimens expressed programmed death-1. Median follow-up was 9 years. Although no patient developed erythroderma, tumors, or abnormal lymph nodes, specific skin lesions appeared in all patients during follow-up. Only 1 death, unrelated to Sézary syndrome, occurred. Limitations Retrospective design and small sample size are limitations. Conclusion Sézary syndrome without erythroderma is a rare entity that may have a better prognosis than classic Sézary syndrome.
