An Uncommon Cause of Peritonitis: Perforation of Undiagnosed Gastric Cancer

Gastric cancer, while common, rarely presents as an acute surgical emergency, with perforation occurring in less than 5% of cases. This report details a 53-year-old male who presented with abdominal pain and vomiting, leading to a diagnosis of perforated gastric adenocarcinoma confirmed by imaging and subsequent total gastrectomy. The case underscores the challenges of diagnosing perforated gastric cancer, which often mimics benign conditions. Effective imaging, especially CT scans, is crucial for timely diagnosis and management. Given the high mortality associated with surgical interventions, further research is needed to establish standardized treatment guidelines for this rare complication.
