Histopathology Artifacts Quiz
This is a tie breaker slide and I found this one quite difficult myself when I had a sneak preview. In other words I got it wrong. If you look very closely there is an amorphous substance in the lumen. This is retained barium after the patient had a barium meal. And if you looked real closely you will also have seen this oval looking structure which isn't an ovum of a worm but the seed of a plant. So the answer is retained barium and a plant seed. You can give yourself a mark for each part of the answer. One for barium and one for plant seed.
