Abstract
Background
Teratomas originating from the stomach are extremely rare and account for less than
1% of all cases of teratomas. This site of occurrence has unique diagnostic and management
issues.
Methods
A single centre case-record review of gastric teratomas presenting between January
2000 and April 2017 was performed.
Results
Thirteen children were found to have gastric teratomas. Presenting features were abdominal
distension in 12 (92%) and palpable abdominal mass in 9 (69%). At operation, 8 (61%)
were exogastric tumors. The tumor was excised with partial gastrectomy (n = 7, 54%), total gastrectomy (n = 1, 8%), partial gastrectomy and limited transverse colectomy (n = 2, 15%), and excision of small part of serosa (mucosal sparing) (n = 3, 23%). Histopathologically, these were identified as mature gastric teratomas in
8 (61%). Three (23%) children died postoperatively.
Conclusion
Gastric teratomas are rare, with the majority described as exogastric. Partial gastrectomy
is always needed, but occasionally complete gastrectomy is necessary. Overall survival
is >75% in our experience.
