In lymphocytic gastritis, the lamina propria and pit epithelium are infiltrated by large numbers of small mature T lymphocytes. Abundant T lymphocytes typically permeate the surface epithelium. A diagnosis can be rendered when 30 or more lymphocytes are observed per 100 consecutive epithelial cells, and performing the counts in biopsies from the gastric corpus is recommended.
