SOCARRAS FERRER, Berta Beatriz et al. Application of flow cytometry in the immunological diagnosis of cutaneous T-cell lymphomas. Rev Cubana Hematol Inmunol Hemoter [online]. 2007, vol.23, n.2, pp. 0-0. ISSN 1561-2996.

The immunophenotypic characteristics of 7 patients (5 males and 2 females) with the clinical-morphological diagnosis of cutaneous T-cell lymphoma that received attention at the Hematology service of the Institute of Hematology and Immunology were reported. The patients were between 17 and 88 years old. The immunodiagnosis was made by direct immunofluorescence with a panel of monoclonal antibodies that included B and T lymphoid markers: CD2, CD3, CD4; CD5, CCD7, CD8, CD19, CD22 and CD25.   The reading was obtained in a FaCScan (Becton-Dickinson) flow cytometer. Every marker was considered positive if a percentage over 20 % expressed the antigen. Our results showed the prevalence of the general pattern of T lymphocytes with auxiliary function (CD3+, CD4+, CD8-). It was proved that flow cytometry is a faster and less laborious than other methods of cellular phenotyping, allowing an accurate diagnosis and the application of an effective therapy.
