Nuclear atypia refers to abnormal appearance of cell nuclei. [1] It is a term used in cytopathology and histopathology. Atypical nuclei are often pleomorphic.

Nuclear atypia can be seen in reactive changes, pre-neoplastic changes, [1] and malignancy. Severe nuclear atypia is, in most cases, considered an indicator of malignancy.
