Exploring the boundaries between neoplastic and reactive lymphoproliferations: lymphoid neoplasms with indolent behavior and clonal lymphoproliferations-a report of the 2024 EA4HP/SH lymphoma workshop.

ABSTRACT: The boundaries between neoplastic and reactive lymphoproliferations were discussed during the 2024 European Association for Haematopathology/Society for Hematopathology workshop in Dubrovnik, Croatia. Session 5 focused on indolent lymphoid neoplasms and clonal lymphoproliferations. Seventy-two cases were submitted, representing good examples of indolent lymphomas and lymphoproliferative disorders (LPD) and their diagnostic challenges. The morphologic spectrum of primary cutaneous marginal zone lymphoma/lymphoproliferation (PC-MZL/PC-MZLPD) was discussed. PC-MZL/PC-MZLPD is divided in the immunoglobulin heavy chain switched-type and non-switched-type with some clinicopathological differences. The overlapping features between PC-MZL/PC-MZLPD and PC-CD4 + T-cell LPD were highlighted. The crit
