The Arias-Stella reaction revisited
Archives of Pathology & Laboratory Medicine
|December 1, 1978
Abstract:
The Arias-Stella reaction was observed in five cases of normal human gestational endometrium. The earliest case was in the endometrium lodging an ovum having an estimate age of 17 days. The Hertig collection at the Carnegie Institute constitutes the basis of the present study. This finding further supports the belief that the Arias-Stella reaction is a physiologic endometrial response to viable trophoblastic tissue.
