Successful delivery after conservative resectoscopic surgery in a patient with a uterine tumor resembling ovarian sex cord tumor with myometrial invasion

Uterine tumor resembling ovarian sex cord tumors (UTROSCT) is an extremely rare type of uterine stromal neoplasm that exhibits prominent sex cord-like differentiation. The clinical characteristics of a UTROSCT are not fully understood. Most reported cases of UTROSCT were treated by hysterectomy with or without bilateral salpingo-oophorectomy; however, a few cases have been treated by only tumor resection in patients who had a strong desire to preserve their fertility. We present a case of UTROSCT with myometrial invasion, which resulted in a successful delivery after the patient was treated by resectoscopic surgery and conservation of the uterus, and a brief review of the literature.

Uterine tumor resembling ovarian sex cord tumors (UTROSCTs) are uncommon neoplasms that histologically resemble ovarian sex cord tumor. Over 50 cases have been reported up to recently. Clement and Scully reported 14 cases of UTROSCT, which they devided into two groups by clinicopathological features. Group I tumors are endometrial stromal sarcomas with partially sex-cord like elements (less than 40% of total tumor volume). On the other hand, group II tumors are mostly or entirely composed of sex-cord like elements. We have experienced a very rare case of type II UTROSCT at the uterine fundus in a 52-year-old woman and report it with a brief review of the literatures.

Uterine tumor resembling ovarian sex-cord tumor (UTROSCT) were first described by Clemen and Scully in 1976. They are a heterogenous group of uterine neoplasm characterised by pure or predominant histological patterns that resembled sex cord tumors of ovary. Clemen and Scully divide the tumors into two groups according to sex-cord-like structures within tumors (the so-called group I tumors with 50% of sex-cord elements, the so-called group II tumors with almost completely sex-cord-like structures). The histogensis of the sex-cord-like elements is uncertain, the group I tumor appears to be more malignant. We experienced a case of UTROSCT in a 44 years old woman underwent LAVH under tantative diagnosis of uterine myoma and report the case with brief review of literature.

Uterine Tumor Resembling Ovarian Sex-Cord Tumor: A case report

The authors report a case of uterine tumor resembling ovarian sex-cord tumor in a 31-year-old woman with emphasis on immunohistochemistry. Histologically this case showed identical features to a well-recognized endometial stromal tumor except for focal epithelial-like differentiation that resembled sex-cord tumors of the ovary. The sex-cord like differentiation of tumor cells were manifested by trabeculae, plexiform cords, and gland-like pattern. We diagnosed this case, according to the features described by Clement and Scully(1976), as uterine tumor resembling ovarian sex-cord tumor, group I. Although the histogenesis of this tumor is unclarified, most authors believe that this tumor may be originated from multipotent mesenchymal cells of the uterus. On immunohistochemical stains, Desmin was uniformly reactive in epithelial-like cells and in focal areas of endometrial stromal sarcoma-like component. Vimentin was partly reactive in all tumor components, however EMA was non-reactive.
