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”
61-year-old female with a 12 mm flat elevated polyp in the caecum removed by EMR. What’s your diagnosis?
The smoking gun?
Signet ring changes in gastric and colorectal biopsies
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”
Some thoughts on resilience.
As a biologist first, with medicine as my second career I often think of resilience as it applies to the natural world. If humans were wiped out by a meteorite or a new pandemic tomorrow it wouldn’t take very long for vegetation to engulf our cities and erase the superficial evidence of centuries of modern … Continue reading “Some thoughts on resilience.”

The nomadic digital pathologist
I often use a “cars and roads”analogy to explain certain aspects of #digitalpathology . Large high throughput scanners can be compared to fast cars, but without good quality roads linking large cities (hospitals) they can gather dust in the garage.In this article, I explain that you don’t necessarily need a Porsche or a Lamborghini to … Continue reading “The nomadic digital pathologist”
