A Rare Case of an Advanced Gastric Adenocarcinoma in a Teenage Syrian Boy.

In this report, we describe a case of a gastric cancer in young age group with delayed diagnosis and poor prognosis. We report a rare case of a 16-year-old teenager with an advanced moderately differentiated gastric adenocarcinoma without any relevant history. He presented mainly with dysphagia, postprandial vomiting, and eventually hematemesis. On exploratory laparotomy, the tumor was in advanced stage, the excision was not performed, multiple biopsies and a feeding jejunostomy were done, and the patient was referred to receive a palliative therapy. Reporting such cases introduces a better understanding of the relation between gastric cancer and young ages.
