Essential thrombocythemia is frequently associated with abdominal thrombotic complications including portal cavernoma as a consequence of chronic portal vein thrombosis. Essential thrombocythemia in a latent form is difficult to identify at onset due to the absence of an overt disease phenotype. In the presented case report, the diagnosis of essential thrombocythemia was initially missed because the typical disease phenotype was masked by bleeding and hypersplenism. The correct diagnosis was only reached when the patient experienced persistent thrombocytosis and pseudohyperkalemia after a shunt operation.

Multiple myeloma (MM), essential thrombocythemia (ET), and colorectal adenocarcinoma (CA) are three distinct diseases. The co-occurrence of MM, ET, and CA in a single patient is exceedingly rare. Our study presents a remarkable case involving a 75-year-old patient who was simultaneously diagnosed with these three diseases.

The efficacy of statins as anti-cancer drugs has been demonstrated in several malignancies but has been poorly investigated in hematological malignancies (HM). By studying its effect on oncogenic miRNAs, we investigated the effect of statin therapy on HM patients. The data were used to identify enriched pathways that were altered due to statin treatment.

Essential thrombocythemia (ET) is a type of myeloproliferative neoplasm (MPN) disorder characterized by persistent thrombocytosis and characterized by frequent association with cellular genetic alterations. The 10%-15% of ET that is not associated with genetic abnormalities is known as triple-negative essential thrombocythemia (TNET). A common complication observed in around 20% of ET patients is the development of acquired von Willebrand disease (AvWD).

Primary myelofibrosis (PMF) is an uncommon chronic myeloproliferative disorder that is commonly associated with Janus kinase 2 (JAK-2), calreticulin (CALR), or thrombopoietin receptor (MPL) mutations. Pre-fibrotic PMF (also known as pre-PMF or early PMF) is a subtype of PMF that is defined by a lower grade of fibrosis. In this report, we present a rare case of warm autoimmune hemolytic anemia (wAIHA) associated with pre-PMF.

Objective: To analyze the genes related to platelet activation in essential thrombocythemia (ET) based on transcriptome sequencing technology (RNA-seq), and to explore the potential targets related to ET thrombosis.

Methods: Blood samples from ET patients and healthy individuals were collected for RNA-seq, and differentially expressed lncRNAs, miRNAs, and mRNAs were selected to construct a lncRNA-miRNA-mRNA regulatory network. Differential mRNAs in the regulatory network were enriched and analyzed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG).
