The 8p11 myeloproliferative syndrome (EMS), also called stem cell leukemia/lymphoma (SCLL), is a rare disease that is characterized by rapid progression to acute myeloid leukemia and poor response to treatment. The only curative approach is allogeneic hematopoietic stem cell transplantation. Non-random cytogenetic abnormality is a translocation at the 8p11 locus, which involves the fibroblast growth factor 1 (FGFR1) gene.

A new case of EMS/SCLL in a 19-year-old female is presented, which was diagnosed in July 2009. According to clinical and laboratory parameters this was a typical form of the disease, e.g., association of a bcr/abl-negative myeloproliferative disorder and a T-cell lymphoblastic lymphoma. WBC at diagnosis was 375.0 x109/l. Bone marrow was hypercellular with myeloid hyperplasia, and contained 8% blasts. Erythropoiesis was decreased; megakaryocytes had dysplastic features. A lymph node biopsy showed T-cell lymphoma with CD2, CD3, CD5, TdT-positivity, and CD34-negativity. The Ki-67 antigen was positive in 50% of neoplastic cells. Cytogenetic study revealed a translocation t(6;8)(q27;p11) which has been confirmed by mFISH. The allogeneic unrelated bone marrow transplantation was carried out in March 2011, which allowed the achievement of complete clinical and cytogenetic remissions, evidenced serially.
