E-mail: kroschinsky{at}mk1.med.tu-dresden.de We investigated cup-like nuclear morphology of acute myeloid leukemia blasts in 266 randomly selected patients and its association with hematologic findings, disease markers and outcome data. Cup-like acute myeloid leukemia was diagnosed in 55 patients (21%). It was associated with female sex, high white blood cell and blast cell counts, normal karyotype, and low CD34 and HLA-DR expression. Mutations of FLT3 , NPM1 or both were detected in 84.9% compared with 58.1% in cases without this morphology ( p =0.001). There was no influence on response to treatment or survival. Therefore, cup-like nuclear morphology is an indicator of normal karyotype and should guide more specific molecular analyses. Key words: acute myeloid leukemia, morphology, cup-like, FLT3, NPM1.
