Autoimmune Atrophic Gastritis
Differential Diagnosis
- Helicobacter associated chronic gastritis can result in antral atrophy with or without intestinal metaplasia that is indistinguishable from the atrophic body mucosa of autoimmune gastritis
- Endocrine cell hyperplasia is not typical of Helicobacter
- Clinicopathologic correlation with knowledge of the location of the biopsy is necessary for the distinction
