Differential Diagnosis for Diffuse Atrophic Mucosa with Patches of Erythematous Mucosa in Stomach

  • Single Most Likely Diagnosis
    • Chronic atrophic gastritis: This condition is characterized by the thinning of the stomach lining, leading to atrophy of the gastric mucosa, which can cause diffuse atrophy and patches of erythematous mucosa due to inflammation.
  • Other Likely Diagnoses
    • Helicobacter pylori infection: H. pylori is a common cause of chronic gastritis, which can lead to atrophic changes and erythematous patches in the stomach mucosa.
    • Autoimmune gastritis: This condition involves the immune system attacking the stomach lining, leading to atrophy and inflammation, which can present with diffuse atrophy and erythematous patches.
    • Gastric mucosal atrophy due to long-term use of proton pump inhibitors (PPIs): Long-term use of PPIs can lead to atrophic changes in the stomach mucosa.
  • Do Not Miss Diagnoses
    • Gastric cancer: Although less likely, gastric cancer can present with atrophic changes and erythematous mucosa, making it crucial not to miss this diagnosis due to its severe consequences.
    • Lymphoma: Gastric lymphoma can cause atrophic changes and inflammation in the stomach mucosa, and missing this diagnosis could have severe implications.
  • Rare Diagnoses
    • Menetrier's disease: A rare condition characterized by large folds in the stomach lining, which can lead to atrophy and erythematous changes.
    • Zollinger-Ellison syndrome: A rare disorder that causes excessive acid production, leading to atrophic changes and inflammation in the stomach mucosa.
    • Eosinophilic gastritis: A rare condition characterized by an accumulation of eosinophils in the stomach lining, leading to atrophy and inflammation.
