Gastric immature teratoma arising from the lesser curvature of the stomach: A rare case report

Immature gastric teratoma is an uncommon germ cell tumor of the stomach. A 6-month-old male child was born through full-term vaginal delivery. After 1 month presented with a history of abdominal distension and palpable mass along with a history of Malena for the past 10 days. Computed tomography scan showed the presence of a large well-defined multilobulated solid cystic lesion with multiple calcifications in the abdominopelvic region. Radiological findings were suggestive of germ cell tumors. The exploratory laparotomy findings showed a large tumor mass with variegated consistency arising from the lesser curvature of the posterior wall of the stomach. The total excision of mass and primary closure of the gastric wall was done. Histopathology of excised specimens showed immature teratoma of the stomach. The child is still on follow-up regularly visited as outpatient, doing well day-to-day activity. We report a very rare case of immature gastric teratoma in an infant on the basis of clinicoradiological and pathological findings.
