摘要：

畸胎瘤是先天性胚胎源性肿瘤，发生于胎盘者罕见。现报告1例胎盘成熟性畸胎瘤，患者为23岁女性，产前超声检查发现一界限清晰、有包膜的混合回声团通过一带状结构与胎盘胎儿面相连，内探及后伴声影的多发强回声斑，考虑为胎盘畸胎瘤。此后定期超声复查，混合回声团大小及回声均未见明显变化，孕40+5周经阴道分娩一女活婴。胎盘顺利娩出，肉眼观察胎盘边缘可见一黄色组织，经产后病理证实为胎盘成熟性畸胎瘤。通过本例，总结胎盘畸胎瘤的特点，提高对该病的认识，以期为临床诊疗提供参考。

Abstract:

Teratoma is a congenital embryogenic tumor, and its occurrence in the placenta is rare. A case of mature teratoma of the placenta is reported here. The patient was a 23-year-old woman. Prenatal ultrasound examination revealed a well-defined, encapsulated mixed-echo mass connected to the fetal surface of the placenta through a band-like structure. Multiple strong-echo spots with posterior acoustic shadows were detected inside, and placental teratoma was considered. Subsequently, regular ultrasound re-examinations were conducted, and no obvious changes were found in the size and echo of the mixed-echo mass. At 40+5 weeks of gestation, a live female infant was delivered vaginally. The placenta was delivered smoothly. A yellow tissue was observed at the edge of the placenta with the naked eye, and it was confirmed as a mature teratoma of the placenta by postpartum pathology. Through this case report, the characteristics of placental teratoma are summarized to improve the understanding of this disease, with the hope of providing a reference for clinical diagnosis and treatment.
