Abstract Diffuse large B-cell lymphomas (DLBCL) with aberrations of MYC probably represent a distinct clinicopathological entity following an aggressive course. Their incidence in unselected DLBCL collectives is debatable and the identification of such cases may be difficult. Therefore, the molecular epidemiology of MYC aberrations in DLBCL and whether they can be predicted by morphology and immunohistochemistry were studied on tissue microarrays containing 333 cases. Evaluation of MYC by fluorescence in situ hybridisation was successful in 220/333 (66%) cases. 9/220 (4%) cases showed MYC breaks. Re-evaluation of these tumours did not show any specific morphological and/or immunohistochemical features. The median survival time was 9 months for the respective patients, as opposed to 80 for patients without MYC breaks. The presence of MYC breaks in DLBCL cannot be reliably predicted by conventional methods. Since such patients might profit from different forms of treatment, routine testing of all DLBCL for MYC aberrations is suggested.
