Genetics and genomics of ovarian sex cord-stromal tumors.
Ovarian sex cord-stromal tumors (SCST) represent approximately 8% of malignant ovarian tumors. The most common are granulosa cell tumors (GCT) which account for approximately 90% of malignant SCST. Recent studies have unraveled the key genomic and genetic events contributing to their pathogenesis. SCST are found in the hereditary syndromes: Peutz-Jeghers syndrome, Ollier disease and Maffucci sy...

متن کاملSex cord stromal tumors-unusual presentations.
OBJECTIVES The sex cord stromal tumors (SCST) account for approximately 7% of all malignant ovarian tumors. They are endocrinologically active tumors of which granulosa cell tumors are the commonest. We describe an analysis of all cases of SCST managed, in our department over the last five years and discuss two cases of unusual presentation of these tumors. METHODS Ten cases of SCST which wer...
متن کاملUterine tumors resembling ovarian sex cord tumors. A case report.
Uterine tumors resembling ovarian sex cord tumors (UTROSCT) are rare, usually benign, polypoid or nodular neoplasms which generally arise in the fourth to sixth decade of life. We report a case of a 74-year-old woman who presented with vaginal bleeding and remarkable uterine enlargement. Abdominal hysterectomy with bilateral salpingo-oophorectomy was performed and a diagnosis of UTROSCT was mad...
متن کاملDevelopment of sex cord stromal tumors after heterotopic transplantation of cryopreserved ovarian tissue in rats.
Chemoradiotherapy has substantially improved life expectancy in young women with cancer, but these treatments often cause infertility. One method of preserving fertility is to cryopreserve ovarian tissue, with subsequent autotransplantation of the tissue after successful anticancer therapy. This study examined the long-term effect of heterotopic transplantation of cryopreserved ovarian tissue o...
