Introduction:
Peripheral T-cell lymphomas are rare, aggressive malignancies with significant diagnostic challenges due to their heterogeneity.
Materials And Methods:
This retrospective study analysed 43 nodal Peripheral T-cell lymphomas cases diagnosed between 2019 and 2024 at the Blood Transfusion Hematology Hospital in Southern Vietnam and reclassified them using the World Health Organization 2022 classification.
Results:
Nodal T-follicular helper cell lymphoma, angioimmunoblastic type, emerged as the most prevalent subtype (51.2%), markedly exceeding rates reported in Western (32.5%) and East Asian studies (36.2%). Despite the higher prevalence of Epstein-Barr Virus in Vietnam, the proportion of Epstein-Barr Virus positive in Peripheral T-cell lymphomas was not elevated (20%), suggesting additional genetic or environmental factors influencing lymphoma pathogenesis.
Conclusion:
These findings underscore the critical role of updated diagnostic standards and the utility of advanced markers in improving Peripheral T-cell lymphomas classification. This study provides rare insights into Peripheral T-cell lymphomas pathology in Vietnam, contributing valuable data to the global understanding of these rare lymphomas.

The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
