ABSTRACT

Inflammatory hematological diseases (IHDs) represent a complex group of disorders characterized by immune dysregulation affecting hematologic function. This chapter provides a structured overview of IHDs, focusing on current classification systems and challenges in standardization. Beginning with the definition and pathogenesis of IHDs, it traces the evolution of classification nomenclature, highlighting historical cases and the progression toward integrated genetic, immunologic, and phenotypic criteria. Key limitations, such as the overlap with autoimmune and autoinflammatory conditions, are examined, illustrating the need for more precise diagnostic boundaries. Commonly accepted frameworks, including genetic markers, immune pathway disruptions, and clinical phenotypes, are reviewed to outline current classification methods. Addressing the pressing issues in achieving universal classification, this chapter explores emerging concepts in precision medicine, biomarker discovery, and AI-driven diagnostics. By reflecting on both historical insights and future innovations, it aims to guide hematologists in navigating the complexities of IHD classification, ultimately facilitating improved patient outcomes.
