Abstract：One case of yolk sac tumor with primary endometrium in a postmenopausal woman was reported.The patient was a 57-year-old woman with postmenopausal vaginal bleeding,accompanied by the elevated level of serum tumor marker alpha-feto protein(AFP).Gynecological ultrasound showed the thickening endometrium and uneven echo,abundant blood flow,and a right uterine cavity mass lesion.Pelvic magnetic resonance imaging showed the abnormal signal shadows in the myometrium and intrauterine cavity.On January 2,2024,the patient underwent transabdominal total hysterectomy+double salpingectomy+pelvic and abdominal para-aortic lymph node dissection+omentectomy,and the postoperative pathological results suggested endometrial yolk sac tumor.As of May 2024,the patient has undergone 6 rounds of chemotherapy and is generally in good condition,with no recurrence or metastasis.The primary endometrial yolk sac tumor in postmenopausal women is highly malignant,with poor prognosis and the non-specific clinical manifestations.The diagnosis mainly depends on pathological examination and immunohistochemical examination.The early detection,early diagnosis and individualized treatment plan are the key factors to improve the prognosis of patients.
