Artificial Intelligence versus immunohistochemistry

Pathologists often use immunohistochemistry (IHC) to confirm what we already know, or strongly suspect from the H&E slide. AI can now assist us in a similar way such as identifying a tiny focus of cancer in a gastric biopsy, for which we might use a cytokeratin immunostain for confirmation. Like IHC it will allow us … Continue reading “Artificial Intelligence versus immunohistochemistry”

Despite these concerning features, both are from benign conditions. The first (Figure 1A) is from a fundic gland polyp in a patient on long-term proton pump inhibitor therapy. The gastric gland epithelial cells have exuberant cytoplasmic vacuolation which can be demonstrated using anti-H+ ATPase antibody immunohistochemistry and ABPAS to be parietal cells and to lack … Continue reading “Signet ring changes in gastric and colorectal biopsies”
