Immature teratoma of the stomach in the neonate is extremely rare.1(,)2 This report outlines a case of giant immature teratoma of the stomach, which was detected by prenatal ultrasonography in the third trimester as an echogenic mass contiguous with the stomach bubble. It increased from 4.5 cm in diameter to 7 cm between 34 and 37 weeks gestation. The baby was delivered by elective caesarean section at 37 weeks gestation. Neonatal imaging highlighted a differential diagnosis of nephroblastoma, neuroblastoma, pancreatoblastoma and teratoma. The infant underwent surgical excision of the abdominal mass on the 10th day of life. Histology revealed grade III immature gastric teratoma arising from the posterior wall of stomach, outlining the unknown implications of such a designation in an extraovarian site. The infant made a good postoperative recovery and is currently well 9 months later, without adjuvant therapy, and with no evidence of recurrent disease.
新生儿胃未成熟畸胎瘤极为罕见。本报告概述了一例巨大的胃未成熟畸胎瘤病例，该病例在孕晚期通过产前超声检查发现为与胃泡相邻的强回声肿块。在妊娠34至37周期间，其直径从4.5厘米增大至7厘米。婴儿在妊娠37周时通过择期剖宫产分娩。新生儿影像学检查突出了肾母细胞瘤、神经母细胞瘤、胰腺母细胞瘤和畸胎瘤的鉴别诊断。婴儿在出生后第10天接受了腹部肿块的手术切除。组织学检查显示为起源于胃后壁的III级未成熟胃畸胎瘤，凸显了这种在卵巢外部位的病变的未知影响。婴儿术后恢复良好，9个月后目前状况良好，未接受辅助治疗，也没有疾病复发的迹象。
