Abstract: Introduction: Gastric teratoma in neonatal period, accounts for less than 1 % of all teratomas with less than 200 cases being reported in literature. It is an extragonadal germ cell tumors composed of all the 3 layers ? ectoderm, mesoderm, endoderm. Stomach is an unusual site, with presentation seen as early as infancy. Case Presentation: Day of life 9, full term, male child was referred with chief complaint of gross abdominal distention gradually increasing from birth, with a visible epigastric lump and left inguinal hernia. It was a huge mass occupying epigastric and left hypochondriac region measuring 10*8*5 cm, well defined, variegated surface, moving with respiration. CT scan reported a solid, cystic mass (10.5 ? 7.8 ? 6.2cm), occupying mainly left upper quadrant, containing septations with coarse calcifications. The diagnosis of intrabadominal mass was established, considering the differentials of mesenteric cyst, teratoma, gastric lymphoma. The tumor was en-bloc resected, along with the part of the gastric wall. Postoperative course was uneventful. On histo-pathological examination, it was an immature grade 2 teratoma and complete remission was seen by en-masse resection. Conclusion: Gastric teratoma is a rare neoplasm, with resection being it?s, the-line of management, owing to its benign course. Given the rarity of this case, this case report underscores the importance of considering it in its differentials.
