Peripheral T-cell lymphomas with gamma-delta phenotype (GDTCL) are rare lymphoid malignancies. Beyond the well-recognized entities of extranodal lymphomas with gamma-delta phenotype as defined by the fifth edition of the World Health Organization Classification of Hematolymphoid Tumors and 2022 International Consensus Classification, there is a group of poorly defined gamma-delta T-cell lymphomas with predominantly nodal presentation, termed as nodal GDTCL (nGDTCL). In this study, we present a series of 12 cases of Epstein-Barr virus-negative nGDTCL, highlighting the clinical, histopathological, and molecular features of this rare entity.
