Sclerosing stromal tumor is an uncommon ovarian neoplasm that has only recently been defined and distinguished from fibrothecoma. This case report describes a 17-year-old patient who presented with a large sclerosing stromal tumor and a smaller mature teratoma in the left ovary. Eighteen months later, an immature teratoma was discovered in the contralateral ovary and microscopic spread outside the ovary was documented at staging laparotomy. Mature and immature teratomas have been observed in opposite ovaries in a small number of patients. However, sclerosing stromal tumor, in over 60 published cases, has not been associated with other forms of ovarian neoplasia. Gonadal stromal differentiation, in fact, has not been convincingly demonstrated in teratomas. The observations in this case, therefore, appear to be unique.
