<正>Sclerosing stromal tumor (SST) is a rare type of ovarian tumor, first described by Chalvardjian and Scully in 1973 as a distinct subtype in the thecoma-fibroma group. However, to our knowledge, it has never been reported to be associated with other forms of sex cord components. We report an unusual case of SST with minor Sertoli elements, an apparently unique association.
