Extranodal Marginal Zone Lymphoma: Integrating Etiology, Microenvironment, and Genetics Into Clinical Decision‐Making

European Journal of Haematology, EarlyView.
ABSTRACT Extranodal marginal zone lymphoma (EMZL) represents a unique paradigm among indolent B‐cell neoplasms, in which lymphomagenesis is frequently driven by chronic antigenic stimulation within tissue‐specific microenvironments. Persistent infectious or autoimmune triggers promote the development of ectopic lymphoid tissue and sustain B‐cell ...
