What's The Definition Of The Medical Condition Tumor, Sex Cord-Stromal?

A malignant neoplasm of the ovary or testis. These tumors differentiate toward sex cords (in embryonic gonads) in the form of female (i.e., granulosa and theca) cells, male (i.e., Sertoli and Leydig) cells, or indifferent elements. In the ovary, sex cord-stromal tumors comprise 5% of all ovarian neoplasms. In the testes, Leydig and Sertoli cell tumors comprise about 5% of all testicular neoplasms, 10% of which behave in a malignant fashion. (From Segen, Dictionary of Modern Medicine, 1992)
