Abstract：
UNASSIGNED: Gastric teratoma is an extremely rare tumor, representing <1% of all pediatric teratomas, and commonly manifests as a palpable abdominal mass. Upper gastrointestinal tract bleeding in newborns and infants is rare and is mostly caused by a benign lesion.
UNASSIGNED: We present a 3-month-old boy who presented with recurrent attacks of hematemesis, vomiting, and melena which on work up revealed a gastric teratoma.
UNASSIGNED: Owing to the unique characteristics and the extreme rarity of this entity, accurate preoperative diagnosis has remained elusive.
