Phlegmonous Gastritis: A Case Report of Successful Early Antibiotic Treatment.

Phlegmonous gastritis (PG) is a rare and serious bacterial infection of the gastric submucosa. Diagnosis is often delayed due to nonspecific symptoms, but if recognized early, PG may be treated successfully with medical therapy alone. We describe a case of a 47-year-old patient admitted with gastrointestinal symptoms and sepsis. He was found to have beta-hemolytic streptococcus bacteremia with a purulent gastric ulcer on endoscopic evaluation, consistent with the diagnosis of PG. Though surgical evaluation is often required in cases of PG, our patient quickly improved with parenteral antibiotic therapy. This case highlights an uncommon source of sepsis and demonstrates the success of antibiotic monotherapy with early recognition.
