{Abstract}: Sclerosing stromal tumors are a rare type of ovarian tumor in the category of sex cord stromal tumors, which arise from the ovarian connective tissue. This report concerns a case of a sclerosing stromal tumor in a 19-year-old nulliparous woman who presented with the chief complaints of menstrual irregularities and dyspareunia. Preoperative imaging revealed a complex right adnexal mass with blood flow and without associated ascites. Tumor markers were all normal except lactate dehydrogenase, which was elevated. The elevated lactate dehydrogenase, in combination with patient age and menstrual irregularities, initially misdirected the clinicians toward suspicion for dysgerminoma or other malignant germ cell tumor of the ovary. Clinicians should beware of excluding the diagnosis of sex cord stromal tumor on the differential in a young person with an adnexal mass and elevated lactate dehydrogenase.
