The necessity of surveying the lamina propria at every level from the muscularis mucosae to the epithelium, in order to obtain an accurate estimate of plasma cell frequency is demonstrated. The relative accuracy of counting smaller areas of lamina propria is tested and the ratio of epithelium to lamina propria area established.
