lesser curvature of the stomach and anterior to the pancreas, suggesting either a gastric or retroperitoneal teratoma. The infant was taken to the operating room. The mass was easily

separated from the pancreas posteriorly but was attached to the posterior superior aspect of the stomach at the esophagogastric junction. It was dissected free. The pathology demonstrated

mature adipose tissue, cartilage, bone, bone marrow, smooth muscle, gastric mucosa, brain, choroid plexus, but also foci of immature brain and skin; diagnosed as a congenital immature

teratoma. The gastric resection line was free of tumor. Teratomas are well-known neoplasms arising from totipotential cells with a capacity to differentiate along all three germ

lines—ectodermal, endodermal and mesodermal.1 Gastric teratoma is a very rare condition comprising less than 1% of all childhood teratomas and less than 2% of all neonatal abdominal masses.1

The most common teratomas of childhood are sacrococcygeal (65%), gonadal (20%), mediastinal (10%), intracranial and cervical (5%). Unlike childhood teratomas in other locations, which have

a female predominance of 68%, gastric teratomas occur overwhelmingly in males.2 This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your
