Gastric Adenocarcinoma in a 16-Year-Old Female

Background: Primary gastric adenocarcinoma commonly occurs in the elderly in the sixth to seventh decade of life but is exceedingly rare in children and adolescents, accounting for only 0.05% of pediatric gastrointestinal malignancies. Because of the nonspecific clinical presentation, gastric adenocarcinomas in children and adolescents are often metastatic when they are discovered. Case Report: We describe a case of gastric adenocarcinoma in a 16-year-old female who was diagnosed early and successfully treated with surgery and chemoradiation by volumetric modulated arc technique. Conclusion: The possibility of gastric adenocarcinoma should be considered in children and adolescents with persistent nonspecific symptoms of vomiting and upper abdominal pain so that the diagnosis can be made at early stages and radical treatment can be offered.
