Erratum to: DUSP22-rearranged ALK-negative anaplastic large cell lymphoma is a pathogenetically distinct disease but can have variable clinical outcome

We made non-substantive typographical corrections and the following substantive changes to the original figure of our editorial “DUSP22-rearranged ALK-negative anaplastic large cell lymphoma is a pathogenetically distinct disease but can have variable clinical outcome”¹: WHO 2^nd edition 2001 is changed to WHO 3^rd edition 2001; WHO 3^rd edition 2008 is changed to WHO 4^th edition 2008; and WHO 4^th edition 2016 is changed to WHO Revised 4^th edition 2016.

Figure 1.

Current classification of systemic anaplastic large cell lymphoma. The most common t(2;5) (ALK-NPM) is shown. Rare variant rearrangements involving the ALK gene on 2p23 and different partner genes on other chromosomes can occur in 15-25% of cases of ALK-positive anaplastic large cell lymphoma. ALCL: anaplastic large cell lymphoma; WHO: World Health Organization; ALK: anaplastic lymphoma kinase.
