Lymphadenitis/Reactive-Hyperplasia, Mimickers of Lymphomas, Low-Grade B-Cell Lymphomas, and Hodgkin Lymphoma

A two-day meeting on controversial topics in hematopathology was held in Bologna, Italy, on 19–20 January 2024. The meeting primarily targeted pathologists lacking experience in hematological neoplasms and pathologists in training. The course aimed to highlight practical diagnostic challenges faced by pathologists and discuss solutions through the application of conventional histology, along with appropriate immunohistological, genetic, and molecular findings. The teaching program included lectures and slide seminars presented by a team of expert hematopathologists who were co-authors of the WHO classification of hematolymphoid tumors. Special interest revolved around “lymphadenitis and lymphoma mimickers”, “a rational approach to low-grade B-cell lymphomas”, and “advancements in defining Hodgkin lymphoma”. A key aspect emphasized by the faculty team was the use of the fifth edition of the WHO Bluebook and the International Consensus Classification (ICC 2022) of lymphomas.
