NTRK1-rearranged histiocytosis: clinicopathologic and molecular features. [PDF]
Non-Langerhans cell histiocytoses are a diverse group of histiocytic diseases. Different entities are defined based on clinical, histopathologic, and/or molecular characteristics. This study aimed to define NTRK-rearranged histiocytosis.

Erdheim-Chester disease associated with myeloid neoplasm: Clinical features, molecular landscape, and treatment outcomes. [PDF]
Abstract Erdheim‐Chester disease (ECD) is frequently associated with clonal hematopoiesis and myeloid neoplasms (MN), but clinical phenotype and response to kinase inhibitors (KI) in this setting remain unclear. We analyzed 67 patients with ECD associated with MN (ECD‐MN) from a French national cohort and assessed ECD treatment response, MN progression,

Indeterminate dendritic cell tumor (IDCT) [PDF]
Indeterminate dendritic cell tumor (IDCT) is rare histiocytic tumor characterized by the proliferation of indeterminate dendritic cells. It is more often diagnosed in middle-aged people, in approximately equal proportions in men and women.

Tissue-Resident Myeloid and Histiocytic Cells in Health and Disease: Novel Emerging Concepts. [PDF]
ABSTRACT Although all myeloid cells are considered to derive from hematopoietic stem cells, the cells in each myeloid lineage are heterogeneous populations, and their distribution and functions vary, depending on underlying physiologic and pathologic processes, age, sex, and genetic and epigenetic signatures.

CD1a-positive dendritic cell-enriched pigmented purpuric dermatosis in association with dyslipidemia
Indeterminate cells (ICs) are dendritic cells (DCs) that share the histologic features of Langerhans cells and macrophages but lack Birbeck granules. It remains unclear whether IC histiocytosis is a separate disease entity or a reactive process.
