Abstract:

Ovarian steroid cell tumor, not otherwise specified (SCT-NOS) is a relatively rare ovarian tumor in clinical practice and has certain malignant potential. Patients usually present with virilization signs and are accompanied by abnormally elevated androgen levels. The imaging examination of ovarian SCT-NOS is non-specific, so the preoperative diagnosis is quite difficult. This paper reports a case of ovarian SCT-NOS. The patient was admitted to the hospital due to a 7-day discovery of an abdominal mass and 1-day lower abdominal pain. Gynecological color ultrasound showed an abnormal cystic pelvic mass in the pelvis, torsion was not excluded, and the initially diagnosis was an abdominal cyst. Laparoscopic resection of the left ovarian tumor was performed, and the postoperative pathological diagnosis was left ovarian SCT-NOS. The patient was lost to follow-up after discharge.
