Background: Endometrial stromal nodule is a rare subtype of endometrial stromal tumor. Although such nodules are benign, hysterectomy has been considered the treatment of choice, because evaluation of the margin is required for diagnosis. The similarity between low-grade stromal sarcoma and stromal nodule suggests that stromal nodules might respond to hormonal management.
Case: Twenty-one-year-old nulligravida, diagnosed with endometrial stromal nodule, which decreased in size with leuprolide acetate treatment, underwent local excision of the tumor with preservation of reproductive function.
Conclusion: Hormonal therapy was successful in decreasing the size of this stromal nodule which allowed for conservative management.
