A Rare Case of a Systemic Non-Langerhans Histiocytosis Presenting with Diabetes Insipidus and a Tentorial Mass [PDF]

, 2015
Introduction The histiocytoses are a group of clinically diverse diseases distinguished from one another based on the specific immunophenotype of the lesional cells, implying derivation from the same precursor cell.

Non-Hodgkin's lymphoma with extensive emperipolesis mimicking Rosai–Dorfman disease: A rare case report

Indian Journal of Pathology and Microbiology, 2019
Emperipolesis is the hallmark finding for Rosai-Dorfman disease. Till now many studies in literatures have shown emperipolesis as a finding in other benign as well as malignant conditions.

Megakaryocyte Diversity in Ontogeny, Functions and Cell-Cell Interactions

Frontiers in Oncology, 2022
Hematopoietic stem cells (HSCs) rely on local interactions in the bone marrow (BM) microenvironment with stromal cells and other hematopoietic cells that facilitate their survival and proliferation, and also regulate their functions. HSCs and multipotent

Megakaryocyte emperipolesis mediates membrane transfer from intracytoplasmic neutrophils to platelets

eLife, 2019
Bone marrow megakaryocytes engulf neutrophils in a phenomenon termed emperipolesis. We show here that emperipolesis is a dynamic process mediated actively by both lineages, in part through the β2-integrin/ICAM-1/ezrin pathway.

Gray platelet syndrome: proinflammatory megakaryocytes and α-granule loss cause myelofibrosis and confer metastasis resistance in mice. [PDF]

, 2014
NBEAL2 encodes a multidomain scaffolding protein with a putative role in granule ontogeny in human platelets. Mutations in NBEAL2 underlie gray platelet syndrome (GPS), a rare inherited bleeding disorder characterized by a lack of α-granules within blood
