A1 Reifs, Carmen María Alcántara A1 Salido-Vallejo, Rafael A1 Garnacho-Saucedo, Gloria María A1 Corte-Sánchez, Sofía De la A1 González-Menchen, Alberto A1 García-Nieto, Antonio Vélez AB Sézary syndrome is a primary cutaneous T-cell lymphoma characterized by the triad of erythroderma, lymphadenopathy and circulating atypical cells. The emergence of new molecular targets has enabled the development of drugs such as alemtuzumab, an anti-CD52 monoclonal antibody, which has shown promising results in the treatment of this entity. We report the case of a 70-year-old male with refractory Sézary syndrome in whom treatment with alemtuzumab achieved an 80% skin lesion clearance with complete haematologic and radiologic response. The treatment was discontinued after 4 months due to adverse effects, with the patient showing a sustained response without disease progression after 13 months of follow-up.
