This lymphoma was recently recognised in the 5th edition of the World Health Organization Classification of Haematolymphoid Tumours. A comprehensive review of the existing literature revealed no cytological descriptions of this disease. Here, we present the first description of cytological observations from a touch smear of EBV+ NTNKL. In this case, the cytological features of EBV+ NTNKL included centroblastoid nuclei, resembling diffuse large B\u2010cell lymphoma (DLBCL), along with abundant cytoplasm containing azurophilic granules observable with May\u2013Giemsa staining. These cytoplasmic features are consistent with the cytotoxic T\/NK\u2010cell lineage of the tumour cells. In the cytological diagnosis of EBV+ NTNKL, it is critically important to understand the distinguishing features that differentiate it from morphologically similar DLBCL. It is also necessary to differentiate EBV+ NTNKL from extranodal NK\/T\u2010cell lymphoma, which is an important differential diagnosis in the evaluation of EBV\u2010associated lymphomas. Recognition of the specific cytomorphological features of this lymphoma is of practical significance when fine\u2010needle aspiration cytology, frequently used as an initial diagnostic step for lymph node lesions, is employed and when touch smear cytology is performed to complement histological findings.<\/jats:p>","DOI":"10.1111\/cyt.70082","type":"journal-article","created":{"date-parts":[[2026,4,27]],"date-time":"2026-04-27T06:32:13Z","timestamp":1777271533000},"page":"429-433","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Touch
