Background

Yolk sac tumor (YST) is a malignant entity that often occurs in girls less than 3 years of age and is the most frequent type of primary extragonadal germ cell tumor.

Case

We describe the case of an 11-month-old girl who was referred to our center for vaginal bleeding with evidence of a uterine mass on ultrasonography. Preoperative investigations confirmed YST of the uterine cervix without metastasis.

After 4 cycles of systemic chemotherapy, the patient was treated with laparoscopic trachelectomy (fertility-sparing surgery) without perioperative complications.

Summary and Conclusion

After 12 months of follow-up, no residual mass was seen.

The laparoscopic technique for trachelectomy for uterine cervix YST seems to be feasible and safe in children under 1 year of age.

11个月大女童宫颈卵黄囊瘤腹腔镜气管切除术：最年轻病例

背景

卵黄囊瘤 (YST) 是一种恶性肿瘤，常发生于 3 岁以下的女孩，是最常见的原发性性腺外生殖细胞肿瘤。

案件

我们描述了一个 11 个月大的女孩的案例，她因阴道出血被转诊到我们的中心，超声检查显示子宫肿块。术前检查证实子宫颈 YST 无转移。

经过4个周期的全身化疗后，患者接受了腹腔镜宫颈切除术（保留生育能力的手术），没有出现围手术期并发症。

总结与结论

随访 12 个月后，未见残留肿块。

子宫颈 YST 宫颈切除术的腹腔镜技术对于 1 岁以下儿童似乎是可行和安全的。
