Calreticulin Type 26 Mutation in Myelofibrosis: A Rare Variant With Diagnostic Challenges
Journal of Clinical Laboratory Analysis, EarlyView.ABSTRACT Background Myeloproliferative neoplasms (MPNs) are clonal hematologic disorders commonly driven by mutations in JAK2, MPL, or CALR. Because routine CALR assays are largely optimized for the canonical Type 1 and Type 2 exon 9 variants, rare noncanonical mutations may be missed, creating diagnostic challenges.

Severe Case of Peripheral Leukocytosis Initially Diagnosed as Myelodysplastic Syndrome/Myeloproliferative Neoplasm, Unclassifiable, but Possibly Prefibrotic Primary Myelofibrosis [PDF]
, 2014 Leukocytosis is occasionally seen in patients with presumptive but undiagnosed myeloproliferative disorders (MPD). A 74-year-old woman was admitted to our hospital for tarry stools, anemia, and marked peripheral leukocytosis of 1.4×105/μL ...

Clinical Features and Therapeutic Outcomes in Pyoderma Gangrenosum: A Prospective Cohort Study
JEADV Clinical Practice, Volume 5, Issue 2, Page 495-501, June 2026.ABSTRACT Background Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis highly associated with systemic comorbidities. Accurate diagnosis and treatment remain challenging due to its rarity and clinical mimickers. Objectives To evaluate demographic, clinical features and treatment outcomes in patients referred with suspected PG at a tertiary ...

Molecular Genetics & Genomic Medicine, 2022 The JAK2 gene encodes for a non‐receptor tyrosine kinase that plays a key role in the JAK/STAT signaling transfer pathway. Genetic polymorphisms of this gene have been indicated to be associated with myeloproliferative neoplasm‐associated thrombosis in ...

Methylation of TET2, CBL and CEBPA in Ph-negative myeloproliferative neoplasms [PDF]
, 2010 A loss-of-function mutation of TET2, CBL and CEBPA has been implicated in the pathogenesis or leukaemic transformation of myeloproliferative neoplasm.

Histiocytosis development and clinical variation through the lens of genomics
The Journal of Pathology, EarlyView.Abstract Histiocytic neoplasms are rare haematologic diseases characterised by clonal expansions of cells with a monocyte, macrophage or dendritic cell phenotype. Their clinical manifestations are diverse, ranging from indolent lesions to aggressive systemic disease.

Differential NOD/SCID mouse engraftment of peripheral blood CD34 + cells and JAK2V617F clones from patients with myeloproliferative neoplasms [PDF]
, 2010 We evaluated the NOD/SCID engraftment of CD34 + cells from polycythemia vera (PV) and secondary polycythemia patients (SP) and the JAK2V617F clone before and after transplantation. Peripheral blood CD34 + cells were transplanted intra-femorally.

British Journal of Haematology, EarlyView.Summary This UK‐based retrospective analysis describes real‐world treatment patterns and outcomes in 175 patients with accelerated (AP, n = 69) or blast‐phase (BP, n = 106) ‘Philadelphia‐negative’ myeloproliferative neoplasms (MPN‐AP/BP) diagnosed between 2013 and 2025. Median age at transformation was 71 years.
