Correction: “The 5th edition of The World Health Organization Classification of Haematolymphoid Tumours: Lymphoid Neoplasms” Leukemia. 2022 Jul;36(7):1720–1748

Correction to: Leukemia 10.1038/s41375-022-01620-2, published online 22 June 2022

At the time of original publication, there was an incomplete listing of contributing authors and their institutions. This revision corrects those omissions.

1. Dr Ritsuro Suzuki, Department of Hematology & Oncology, Shimane University School of Medicine, Shimane, Japan, was regrettably omitted from the main author list;

2. Dr Arianna Di Napoli, Department of Clinical and Molecular Medicine, Sapienza University, School of Medicine and Psychology, Sant’Andrea Hospital, Rome, Italy, was incorrectly included as a contributor in the author contribution list, and instead should be a coauthor in the main author list;

3. Dr Luis M. Allende, a contributor in the author contribution list, was assigned with an incorrect affiliation, and the correct affiliation is 70 Immunology Department, Hospital 12 de Octubre, imas12, Madrid, Spain;

4. Dr Aanchal Kakkar, a contributor in the author contribution list, was assigned with an incorrect affiliation, and the correct affiliation is Pathology, All India Institute of Medical Sciences, New Delhi, India.

The above errors have been corrected, and the corrected list of the authors and contributors and their affiliations are as follows.
