A micrograph of an exfoliative cytopathology specimen (Pap test, Pap stain). In this method, cells are collected after they have been either spontaneously shed by the body ("spontaneous exfoliation"), or manually scraped/brushed off of a surface in the body ("mechanical exfoliation").
Peritoneal mesothelioma is the name given to the cancer that attacks the lining of the abdomen.This type of cancer affects the lining that protects the contents of the abdomen and which also provides a lubricating fluid to enable the organs to move and work properly.
Cytopathology of Warthin's tumor, with typical cellular features (and a relatively uncommon binucleated cell). [1] Pap stain. The relatively large size of the oncocytes is seen when comparing to the lymphocyte. Micrograph showing apocrine-type metaplasia of the breast with typical oncocytes. [2] H&E stain.
Micrograph showing the viral cytopathic effect of herpes simplex virus (multi-nucleation, ground glass chromatin). Pap test. Pap stain.. Cytopathic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion.
Micrograph showing peritoneal cytopathology (serous carcinoma), indicating at least Stage IIIA disease. Uterine papillary serous carcinoma is staged like other forms of endometrial carcinoma at time of surgery using the International Federation of Gynecology and Obstetrics cancer staging system.
Micrograph of a pleural fluid cytopathology specimen showing mesothelioma. Diagnosis of mesothelioma can be suspected with imaging but is confirmed with biopsy. It must be clinically and histologically differentiated from other pleural and pulmonary malignancies, including reactive pleural disease, primary lung carcinoma , pleural metastases of ...
Cytopathology is generally used on samples of free cells or tissue fragments (in contrast to histopathology, which studies whole tissues) and cytopathologic tests are sometimes called smear tests because the samples may be smeared across a glass microscope slide for subsequent staining and microscopic examination.
A micrograph showing cells with marked nuclear shape and size variation, a component of nuclear pleomorphism. Pleomorphism is a term used in histology and cytopathology to describe variability in the size, shape and staining of cells and/or their nuclei.
