PLE-7900

A 65-year-old hypertensive male has developed food fear over the last three months. According to his daughter, he has also lost a considerable amount of weight. No changes in bowel movement were noted. The patient is hysterically screaming in the emergency room because of his diffuse abdominal pain. However, on physical examination, you only noted minimal tenderness in the epigastric area. At this point, do you strongly suspect anything?
