The authors have become aware that Dr F Grabellus’s affiliation is not ‘Zentrum fuer Pathologie Essen-Mitte, ZPEM, Am Deimelsberg 34a, D-45276 Essen, Germany’ (as it appears in the above paper) but ‘Institute of Pathology and Neuropathology, University Hospital of Essen, University of Duisburg-Essen, Hufelandstrasse 55, D-45122 Essen, Germany’. The error has now been corrected.
