Chronic eosinophilic leukaemia has not yet been clearly defined, mainly due to the fact that it has not been conclusively shown as a monoclonal disease which should be separated from chronic myelogenous leukaemia, acute myelogenous leukaemia with eosinophilia (AML, FAB M4Eo), and the idiopathic hypereosinophilic syndrome. We report a patient with a white blood cell count of 17.6 x 10(9)/l with 74% eosinophils, normal platelet count and haemoglobin. No blasts were seen in the peripheral blood and the percentage of blasts in the bone marrow was < 3%. A diagnosis of chronic eosinophilic leukaemia was made. Chromosome analysis of a bone marrow aspirate disclosed a trisomy 15 together with loss of the Y chromosome. Moreover, FISH analysis on May-Grünwald-Giemsa-stained peripheral blood smears demonstrated trisomy 15 in the eosinophils. 3 months after initial diagnosis the patient went into blast crisis and died. The blast cells exhibited trisomy 15 and loss of the Y chromosome in a complex, aberrant karyotype. In conclusion, the case shows that chronic eosinophilic leukaemia is a monoclonal, myeloproliferative disease with eosinophils as part of the malignant clone. Clinically, chronic eosinophilic leukaemia can be separated into a chronic phase and a blast crisis.
