Gastric teratoma: A series of 7 cases

BackgroundGastric teratoma is a rare entity comprising less than 1% of germ cell tumors of childhood. We present a series of seven gastric teratomas with a review of literature.ObjectiveTo study the demographic profile, clinicopathological features and follow-up data of gastric teratomas.MethodsWe did a retrospective analysis of 7 cases of gastric teratomas more than 15 years and studied their demographic profiles, clinicopathological features and follow-up data.ResultsWe came across 7 cases of gastric teratomas out of which 5 were mature and 2 were immature. One case of immature teratoma came back with recurrence and another one had an unusual finding of presence of renal and pulmonary tissues, which has not been reported earlier.ConclusionOurs is the second largest case series of gastric teratomas in the pediatric age group and 2 out of 7 of our cases had immature elements. We also take this opportunity to report a case of gastric teratoma with the unusual histological finding of immature renal and pulmonary tissues, which has not been described previously.
