ABSTRACT

Sclerosing stromal tumor of the ovary (SST) is a rare neoplasm of the sex cord stromal category which occur predominantly in the second and third decades of life. Histologically, these tumors are characterized by the pseudolobular pattern of the cellular and hypocellular areas, prominent vasculature and cellular heterogeneity. We report a case of a unilateral SST of the ovary in a 14-year-old girl with irregular menstruation and dysmenorrhea and describe the clinical, radiologic and histologic findings with reference to other reported cases.
