User:Mr. Ibrahem/Sex cord–gonadal stromal tumour

Sex cord–gonadal stromal tumors are a group of tumors derived from the stroma or sex cord of the ovary or testis. They may be benign or cancerous. In women, symptoms may include adnexal mass, abdominal bloating, male pattern hair growth, and menstrual changes. Complications may include ovarian torsion. In males symptoms typically include a painless testicular mass.

Types include granulosa tumors, sertoli cell tumors, sex cord tumor with annular tubules, gynandroblastoma, steroid cell tumors, and Leydig cell tumors. Diagnosis may be supported by medical imaging and blood tests and confirmed by microscopic examination. They are in contrast, to surface epithelial-stromal tumors which arise from the lining around the gonads and germ cell tumors which arise from the precursor cells of the gametes.

Treatment is generally by surgery. This group accounts for 5% of ovarian tumors and 5% of testicular cancers. Different types present at different ages. In females surface epithelial-stromal tumors are more common and in males germ cell tumors are more common.
