BACKGROUND
Persistent elevation in beta-human chorionic gonadotropin (-hCG) following a pregnancy is concerning for gestational trophoblastic neoplasia (GTN). However, the differential diagnosis should remain broad during the evaluation process.
CASE
A 34-year-old G3P3 presented with elevated -hCG four months after cesarean delivery with bilateral tubal ligation. The patient was treated with methotrexate for a presumed new ectopic pregnancy. Due to persistent -hCG elevation, she received actinomycin-D for GTN treatment. After completing chemotherapy, her -hCG increased. The patient underwent a laparoscopic hysterectomy with unplanned left oophorectomy due to its nodular appearance at the time of surgery. Pathology confirmed a dysgerminoma of the ovary and benign uterus.
CONCLUSION
Although dysgerminomas are uncommon, they should be considered when -hCG levels remain elevated despite therapies for more common pathologies.
背景
妊娠后β-人绒毛膜促性腺激素（β-hCG）持续升高提示妊娠滋养细胞肿瘤（GTN）。然而，在评估过程中鉴别诊断范围应保持宽泛。
病例
一名34岁经产妇（G3P3），剖宫产及双侧输卵管结扎术后4个月出现β-hCG升高。患者因推测为新的异位妊娠接受甲氨蝶呤治疗。由于β-hCG持续升高，她接受放线菌素-D治疗GTN。化疗结束后，她的β-hCG升高。患者接受了腹腔镜子宫切除术，术中因左侧卵巢呈结节状外观而意外切除左侧卵巢。病理证实为卵巢无性细胞瘤和子宫良性病变。
结论
尽管无性细胞瘤并不常见，但当针对更常见病因进行治疗后β-hCG水平仍持续升高时，应考虑该病。
