    Hairy Cell Leukemia With Aberrant CD5 and CD23 Expression: A Case Report and a Brief Literature Review. (PubMed, Cureus)
    Aberrant expression of CD5 and CD23 is extremely rare. We present a case of classical HCL expressing both markers, along with a brief review of the literature emphasizing the diagnostic complexities associated with such aberrancy.

    Understanding hairy cell leukemia in the context of mature B-cell neoplasms: tumor microenvironment and extracellular vesicle contribution to disease pathogenesis. (PubMed, Front Immunol)
    Building on this synthesis, we propose that the insights gained from well-characterized lymphoproliferative disorders may serve as a valuable foundation for investigating related yet poorly understood conditions, such as HCL. Furthermore, given the scarcity of both biological samples and reliable preclinical models for rare hematological malignancies, we highlight the strategic role of European biobanks in providing access to well-annotated clinical samples-an essential resource for fostering interdisciplinary collaboration and enabling advanced experimental modelling.

    Hairy cell leukemia: a chronic B-cell lymphoma with unique clinicopathological features and unresolved molecular mechanisms. (PubMed, Blood Adv)
    More recently, 2 BRAF(V600E)-based HCL mouse models have been developed that could be extremely useful both for functional studies and for testing the activity of new drugs. This review aims to summarize current understanding of key pathogenic mechanisms underlying HCL development and discusses major hurdles that need to be overcome in the context of other BRAF-mutated malignancies.

    Immune activation and microenvironmental crosstalk in hairy cell leukemia. (PubMed, Front Immunol)
    In this Mini Review, we summarize how stromal interactions, extracellular-matrix remodeling, and disrupted immune surveillance reinforce therapeutic resistance in HCL, and how BCR and MAPK signaling interact with these circuits. Further, we highlight emerging strategies, including agents that disrupt chemotaxis, adhesion, and immune checkpoints, designed to dismantle microenvironmental support and improve the depth and durability of remission in HCL.
