Arias-Stella reaction
Arias-Stella reaction, also Arias-Stella phenomenon, is a benign change in the endometrium associated with the presence of chorionic tissue.[1]
Arias-Stella reaction is due to progesterone primarily. Cytologically, it resembles a malignancy and, historically, it was misdiagnosed as endometrial cancer.[1]
