Myocytolysis histology
WebA koilocyte is a squamous epithelial cell that has undergone a number of structural changes, which occur as a result of infection of the cell by human papillomavirus (HPV). [1] Identification of these cells by pathologists can be useful in diagnosing various HPV-associated lesions. Koilocytosis [ edit] WebMyocytolysis is a clearing of the sarcoplasm and nuclei, with nuclear enlargement and prominent nucleoli. If seen in endomyocardial biopsy samples from cardiac transplant recipients who are more than a year from transplantation, this finding could be a marker for accelerated coronary artery narrowing that occurs in transplanted hearts.

WebCoagulative necrosis is a type of accidental cell death typically caused by ischemia or infarction. In coagulative necrosis, the architectures of dead tissue are preserved for at least a couple of days.
