Electron Microscopy of Emperipolesis
In a previous communication (1), one of us described the propensity for emperipolesis exhibited by the cells of the mouse ascites lymphocytic tumor, Lymphoma No. 1 (L, 1). Emperipolesis, a term coined by Humble, Jayne, and Pulvertaft (2) to describe the "inside round about wandering" of lymphocytes within cells, has been observed by several investigators to occur under a variety of conditions (...
متن کاملErdheim-Chester Disease with Emperipolesis: A Unique Case Involving the Heart
Histiocytosis is an uncommon disease characterized by excessive accumulation of histiocytes. Here, we report a rare case of non-Langerhans-cell histiocytosis in a 51-year-old woman who presented with severe symptoms of pericardial effusion. Radiologic investigation also detected multiple bone (lower limbs, vertebrae, ribs, and ilium) lesions. Resected pericardium showed abundant mono- or multi-...
متن کاملEmperipolesis, entosis and cell cannibalism: Demystifying the cloud

All these are closely related phenomena with a very fine line of differences. Its correct identification has a significant diagnostic and prognostic value. After extensive literature search, a gap of knowledge was found in concept designing and clarity about u...
متن کاملMegakaryocytic Emperipolesis Associated with Thrombocytopenia: Causative or Coincidence?
Phagocytosis, emperipolesis, and entosis are physiological and pathological phenomena characterized by the engulfment of one cell into another cell [1]. Emperipolesis is defined as active penetration of one cell by another, which remains intact [2]. Emperipolesis differs from phagocytosis in that an engulfed cell exists temporarily within another cell and with an intact normal structure, while ...
متن کاملRetrovirus Pseudomembranous Atrophic Enteritis caused by Suicidal Emperipolesis; A Light and Ultrastructural Study
Benign retroviral infections are common but are usually not recognized. This histologic and ultrastructural study identifies such an infection that became clinically evident in the small bowel following a partial colectomy for multiple micro invasive adenomas. Suspected is a low-grade retroviral infection of myeloid progenitor cells activated by inflammatory cytokines released by the operative ...
