Abstract
We report a case of phlegmonous gastritis that followed an episode of acute pharyngitis. A 21-year-old man visited our emergency room because of intense epigastric pain. Fourteen days before the visit, he had symptoms of a sore throat and high fever. He was diagnosed with acute pharyngitis and treated with antibiotics. Although the symptoms of acute pharyngitis were relieved, epigastric pain began 5 days before the emergency visit. Computed tomography showed diffuse gastric wall thickening, and emergent esophagogastroduodenoscopy revealed diffusely spreading hyperemic mucosa with multiple erosions. He was admitted with a diagnosis of acute phlegmonous gastritis and was treated with antibiotics. The antibiotic treatment was effective and resulted in resolution of his clinical symptoms and normalized C-reactive protein concentrations. On hospital day 29, he was discharged. However, he was re-admitted because of recurrence of phlegmonous gastritis 5 days after discharge and 15 days after finishing the antibiotics. Cultures of gastric biopsies and juice were both positive for Streptococcus constellatus/milleri. Antibiotic treatment was effective, and he recovered without recurrence. A possible association between upper respiratory infections and subsequent phlegmonous gastritis has been reported, and this case supports causality. However, further studies are needed to evaluate causality and pathogenesis.
