A case of gastric teratoma associated with incarcerated left inguinal hernia in a newborn

Abstract

Gastric teratoma is a very rare tumor. Only 46 cases have been reported in the Japanese liturature. We reported a case of 1 day-old male infant with gasric teratoma and the incarcerated left inguinal hernia. The prenatal diagnosis was intestinal atresia with ultrasonography. At operation the tumor was arising from the posterior gastric wall. Tumor was removed with the muscular layer of the stomach. Histological diagnosis was benign teratoma including immature neural tissue cells. A year after surgery, he was healthy and asymptomatic. We performed prenatal ultrasonography, but could not diagnose gastric teratoma. We discussed clinical presentation, surgical treatment and significance of prenatal diagnosis of the gastric teratoma with relevant liteatures.
