Megakaryocyte emperipolesis in myeloproliferative neoplasms: are neutrophils friends or foes?

Journal of Leukocyte Biology
Megakaryocyte emperipolesis is a biological process in which a cell penetrates and exists as a viable intact cell within another. It is a recognized morphological feature of myeloproliferative neoplasms (MPN), where neutrophils can be seen within ...

Inflammatory Myxohyaline Tumor with Massive Emperipolesis

Pathology - Research and Practice, 2002
We report on a 36-year-old man with a recurrent mass on the thenar side of the right hand. Against the background of dense inflammation, inflammatory malignant fibrous histiocytoma was first diagnosed, but typical morphologic features in the recurrent tumor led to a correction of the diagnosis--inflammatory myxohyaline tumor.

High-grade renal cell carcinoma with emperipolesis: Clinicopathological, immunohistochemical and molecular-genetic analysis of 14 cases.

Histology and Histopathology, 2018
Emperipolesis has recently been described as a constant feature of "biphasic squamoid" papillary renal cell carcinoma (BPRCC). We also noticed this in some high-grade (HG) RCC, which promoted the present study to estimate the incidence of emperipolesis ...

Extensive Emperipolesis of Neoplastic Lymphocytes by Mesothelial Cells in Pleural Effusion Cytology in a Case of a Mediastinal T-Cell Lymphoblastic Lymphoma: A Rare but Diagnostically Useful Phenomenon

Acta Cytologica, 2019
Emperipolesis is a biological process defined by the presence of an intact cell within the cytoplasm of another cell. In pleural fluid cytology, the phenomenon is very rare but has already been described in B-cell lymphoma. Here, we report the first case

Emperipolesis of Lymphoid Neoplastie Cells in Feline Hepatocytes

Veterinary Pathology, 1989
Occasional lymphocytes and other leukocytes in guinea pig, rabbit, and human hepatocytes were described in 1944.2 Here we report emperipolesis in the liver of two cats with severe liver damage and intracellular neoplastic lymphoid cells in most hepatocytes.

Emperipolesis: An Unreported Novel Phenomenon in Oral Squamous Cell Carcinoma.

Journal of Contemporary Dental Practice, 2017
Emperipolesis is a phenomenon characterized by engulfment of hematopoietic cells by megakaryocytes, monocytes, fibroblasts, and malignant cells within their cytoplasm. This phenomenon has been reported in various physiological and pathological conditions

Suicidal emperipolesis: a process leading to cell-in-cell structures, T cell clearance and immune homeostasis.

Current molecular medicine, 2015
"Suicidal emperipolesis" is one of the most recently reported processes leading to cell-in-cell structures that promote cell death. This process was discovered in studies investigating the fate of autoreactive CD8 T cells activated within the liver ...
