Abstract:

The uterine tumor resembling ovarian sex cord tumor (UTROSCT), as a special pathological type of primary uterine tumor, is difficult to be diagnosed early due to its extreme rarity and unspecial manifestations in clinical. We report a case of UTROSCT combined with adenomyosis. The patient was admitted to the hospital due to the discovery of uterine fibroids for more than 3 months and intermittent vaginal bleeding for 12 days. The patient was admitted the hospital with a outpatient diagnosis of uterine fibroids. After admission, the relevant auxiliary examinations were completed. Pelvic ultrasound suggested the possibility of uterine fibroids, and there was no obvious abnormalities in tumor markers. Single-port laparoscopic myomectomy and opportunistic salpingectomy were performed. During the operation, the tumor capsule was gray-white, the tumor was extremely soft, and the boundary between the tumor and the uterus was unclear. The intraoperative rapid pathological examination suggested the possibility of small-cell malignant tumor, so total hysterectomy and bilateral adnexectomy were immediately performed. Finally, the postoperative pathology report showed UTROSCT. After 4-year follow-up, the patient′s condition was stable and there was no recurrence. We concluded that surgical treatment is the main treatment for UTROSCT, the prognosis is usually good, and that the possibility of recurrence and metastasis should be noted.
