“…The differential diagnosis of a calcified mass in the left upper abdominal quadrant of a neonate includes mesoblastic nephroma, congenital neuroblastoma, pancreatoblastoma and phaeochromocytoma 8. In this infant, because the kidney was normal on sonography and the abdominal mass appeared separate from it, mesoblastic nephroma was easily excluded.…”

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.

Gastric teratoma is a very rare tumour during infancy and childhood, usually benign and predominantly affects males. We present two infants, one male and a female, 7 and 6 months of age respectively, who presented with distension of the upper abdomen with palpable mass. The 2nd child had feeding problem for 2 days. Imaging studies showed both the tumours arising from the posterior walls of the stomach. In both the patients, the tumours could be completely excised. The histology had shown features of mature teratoma. Both the children are on regular follow up for 12 months and 36 months, respectively and are doing well.

“…Gastric teratomas are very rare, accounting for less than 1% of all teratomas in infants and children (Grosfeld et al, 1976). For unknown reasons, there is a male preponderance with 90% of cases reported in boys and mostly seen in infants (Gupta et al, 2000;Sharma et al, 1994;Matias and Huang, 1973;Gore and Fernbach, 2002;Wildbrett et al, 2012;Sharma et al, 2010). Clinically, the majority present with abdominal distension and a palpable abdominal mass, but there are reports of gastric teratomas presenting with upper gastrointestinal bleeding (Shadi et al, 1996;Hirugade et al, 2001;Haley et al, 1986).…”

“…In grade 1, the immature neuroectodermal tissue is confined to one site in a slide, whereas in grades 2 and 3, the immature tissue is found in less than 4 and more than 4 fields per slide, respectively. Most of the gastric teratomas are con-sidered to be benign but there are reports of malignant gastric teratoma and malignant gastric teratomas have also been reported (Gupta et al, 2000;Sharma et al, 1994;Matias and Huang, 1973;Gore and Fernbach, 2002;Bourke et al, 1997;Balik et al, 1990;Curtis et al, 2008, Saha, 2010. The recommended therapy for gastric teratomas is total surgical excision.…”
