摘　　要：BACKGROUND Epithelioid trophoblastic tumor(ETT)is a special type of gestational trophoblastic tumor.However,its pathogenesis has been incompletely elucidated.ETT rarely occurs in the ovaries and fallopian tubes,unlike placental site trophoblastic tumor,requiring a histopathological biopsy and immunohistochemistry for further diagnosis.CASE SUMMARY A 29-year-old woman with irregular vaginal bleeding and elevated serum chorionic gonadotropin(β-hCG)levels presented similar symptoms to ectopic pregnancy.Transvaginal ultrasound revealed abnormal echoes of the left adnexa.Postoperatively,the pathology of the left ovary and fallopian tube was reported as ETT.The patient was followed up with regular hCG measurements and ultrasounds.The blood hCG values showed an upward trend 3 mo after the operation and then chemotherapy was prescribed.The current health status is normal.CONCLUSION For women of childbearing age with elevated serumβ-hCG levels,practitioners should consider ETT and be alert to the poor prognosis of the disease.After surgery,the patient’s condition should be closely observed to prevent recurrence and metastasis.Postoperative chemotherapy is only helpful for treating the disease to a certain extent.
