Extreme nuclear pleomorphism in a case of glioblastoma.
Some forms of cancer have no or minimal nuclear pleomorphism; mucinous adenocarcinoma of the lung (left of image) looks similar to (benign) gastric foveolar epithelium and in this image is juxtaposed with benign ciliated epithelium (right of image). H&E stain.
Nuclear pleomorphism is a common finding in malignant lesions. Anisonucleosis is often used as a synonym for nuclear pleomorphism; iso- means equal or identical,[1] and an- means not.[2]
Definition
Nuclear pleomorphism is the marked variation of:[3]
- Nuclear size.
- Nuclear shape.
- Nuclear staining (especially with hyperchromasia).
Memory device 3 S: size, shape, staining.
