Steroidogenic acute regulatory (StAR) protein is a rate-limiting protein, which is essential for transporting cholesterol into the mitochondria for steroidogenesis. StAR protein could be a marker for steroidogenic tissues. In this study, we investigated StAR protein levels in sex-cord stromal tumors (SCSTs) including 31 adult granulosa cell tumors, 3 juvenile granulosa cell tumors, 10 fibrothec...

We report the case of a 31-year-old woman with an androgen-producing sclerosing stromal tumor found during the eighth week of gestation in association with ascites and elevated serum androgen and cancer antigen (CA)-125 levels. The combined features of ascites, elevated serum androgen and elevated CA-125 in association with this rare type of ovarian tumor is unusual. Surgical removal of the tum...

Sclerosing stromal tumor (SST) of the ovary is a rare tumor derived from the sex cord stroma. This tumor was first described by Chalvaridjian and Scully in 1973. SST of the ovary is prevalence of 1.5% to 6% of ovarian stromal tumors. Patients are most commonly diagnosed in their 20s and 30s. There have been reports of SST postmenopausal women aged 65-, 67-, and 71 in the Republic of Korea; howe...
