Department of Clinical Haematology, Hospital Geral de São João, Porto, Portugal. elisagranjo@netc.pt Abstract A 23-year-old, white male metallurgist presented with pruritic erythematous maculo-papules over the trunk and upper limbs and 6 months later developed erythroderma, eosinophilia and multi-organ dysfunction. A diagnosis of chronic eosinophilic leukaemia was made on the basis of myeloproliferative involvement of both peripheral blood and bone marrow, associated with eosinophilic differentiation and a t(5;12)(q33;p13) translocation. The initial therapeutic approach was interferon alfa-2b plus cytosine arabinoside, for 13 months, followed by hydroxyurea plus vincristine. There was improvement of skin lesions, disappearance of eosinophilia and decrease of serum immunoglobulin E, towards normal values. Copyright 2002 S.

    Br J Haematol. 2002 Dec;119(3):629-33. Intraclonal diversity in a Sezary syndrome with a differential response to 2-deoxycoformycin of the two lymphoma cell populations. Granjo E, Lima M, Lopes JM, Cunha N, Teixeira Mdos A, Santos F, Candeias J, Resende C, Santos AH, Balanzategui A, Orfão A, Matutes E. Department of Clinical Haematology, Hospital Geral de São João, Porto, Portugal. npp46740@mail.telpac.pt Abstract We report a case of Sezary syndrome with two abnormal CD4+ T-cell populations detected in the peripheral blood by flow cytometry immunophenotyping and DNA cell content, suggesting a biclonal T-cell lymphoproliferative disorder. Despite these findings, molecular analysis of the T-cell receptor genes was consistent with a monoclonal T-cell proliferation, supporting the existence of intraclonal diversity rather than a true biclonal disease. The patient achieved a transient response with 2-deoxycoformycin, with a selective decrease of the larger/hyperploid T-cell population; later on, an increased representation of this T-cell population was observed concomitantly with clinical relapse.
