The authors report five observations of endometrial stromal nodules. These nodules are composed of cells identical to those of the endometrial stroma. They constitute the benign form of endometrial stromal tumors. From the macroscopic point of view, they present as nodular formations, most often single, well defined, non-fasciculated, whitish or yellowish sometimes cystisized. From the microscopic point of view, these nodules contain areas of plexiform or glandular arrangement with, occasionally, pseudo-rosettes. Small collagenous zones can often be observed. E.S.N. should be distinguished on the one hand from endolymphatic stromal myosis, and on the other hand from sarcoma of the endometrial stroma. Histogenesis of the lesion is also discussed.
