Gastric teratoma is a rare tumour accounting for less than 1% of all teratomas in pediatric age groups. We present a case of gastric teratoma in 33-month-old male infant who presented with abdominal pain for 2 months. Ultrasound of abdomen revealed a multi-cystic mass with mixed echogenicity arising from the lesser curvature of stomach. The mass was excised completely and sent for histopathological examination. Histopathology confirmed mixed germ cell tumour (gastric mature teratoma and yolk sac tumour). Serum AFP (alpha fetoprotein) and extensive sampling of the lesions can help in identification of other germ cell component.
