title: Translocation (8;13) and T-cell lymphoma. A case report.
abstract: A patient with a myeloproliferative disorder is described with an eosinophilia together with T-cell lymphoma. A unique translocation t(8;13)(p11.2;q12) was present in all bone marrow cells examined at presentation. No evidence of this translocation was found in a peripheral blood lymphocyte culture. Chromosome analysis after 9 months revealed this same translocation as well as an extra chromosome 21 in all cells; 4.5% of cells also had an additional chromosome 9. The morphologic diagnosis at this stage was chronic myelomonocytic leukemia. Immunophenotyping 3 months later was consistent with a stem-cell leukemia.
