Background/Introduction: Gastric teratoma is an extremely rare tumor, almost
exclusively benign, accounting for < 1% of all teratomas in infants and children.
Purpose/Aim: This work aimed to study the clinical presentation, investigation modalities, intraoperative findings, histopathological types, and surgical outcome of gastric teratoma in children.
Methods: A retrospective study was performed from 1993 to 2013 in two pediatric institutes.
Results: There were eight patients with gastric teratoma and all of them were male. Seven (87.5%) patients presented in infancy, out of which four (50%) patients were neonates, while one (12.5%) patient was a toddler. The manifestations were as follows: a palpable abdominal mass in seven (87.5%), abdominal distension in five (67.5%), anemia in four (50%), respiratory
distress in three (37.5%), gastric outlet obstruction with recurrent vomiting in three (37.5%), and abdominal pain, anorexia, and melena in one (12.5%) each. Ultrasonography showed a solid cystic mass with mixed echogenicity in all the patients, while calcification was seen in
seven (87.5%) cases. Computed tomography, which was performed in four (50%) patients, clinched the preoperative diagnosis. A growth was present on the posteroinferior wall near the greater curvature in seven (87.5%) cases, while in one (12.5%) patient, it was arising from the lesser curvature. Excision of the tumor was performed in all patients. Histopathology was
mature type in six (75%) cases, and immature Grade 1 and 2 in one (12.5%) each. Complications were seen in five (62.5%) cases, and one (12.5%) mortality was observed in our series. All other patients were doing well in the postoperative period.
Conclusion: Gastric teratoma is almost always benign and has predilection for male sex. It commonly presents as a palpable abdominal mass. Complete surgical excision is curative. Close observation is recommended for Grade 2 and 3 immature teratomas. The prognosis is excellent. |
