Abstract Rational: Ovarian sertoli-leydig cell tumor (OSLCT) is extremely rare. We reported a OSLCT case in whom postmenopausal vaginal bleeding was the first symptom. Patient concerns: The patient came to our hospital due to postmenopausal vaginal bleeding. Diagnoses: Serum tumor markers and color Doppler ultrasound for her pelvic cavity were negative. The patient was finally diagnosed with left OSLCT by pathology. It was difficult to make a definite diagnosis before operation, the diagnosis of OSLCT required postoperative pathology in the patients. Interventions: the patient underwent laparoscopic hysterectomy+bilateral adnexectomy+lysis of pelvic adhesions. Outcomes: Postoperative laboratory examinations were normal. The patient was discharged from our hospital on the seventh day after operation and came to our hospital for follow-up check in April 2020. Physical and laboratory examinations were normal. Lessons: OSLCT can show different endocrine abnormalities, which are related to the various types of tumor tissues. Missed diagnosis and misdiagnosis are likely to occur in the patients who only have elevated serum testosterone. For the menopausal women with elevated serum testosterone, ovarian tumor shoule be highly suspected after excluding adrenal gland-related diseases.
