Reactive atypia
Reactive atypia is a term that may be confusing as it contains the word "atypia"; some say it should not be used.[1]
Generally, it is understood as changes due to inflammation or injury without neoplastic change.
A less confusing categorization is:
- Reactive (benign).
- Dysplastic (pre-malignant).
- Indefinite for dysplasia ("I don't know").
Reactive atypia may confuse people between #1 and #2.
Reactive atypia is used by Sternberg.[2]
