Review Question - QID 210950

A 38-year-old man presents to the clinic for complaints of abdominal pain and diarrhea. He reports a long-standing history of the symptoms except for the time when he attempted a carbohydrate-free diet 5 years ago. The pain is described as stabbing, diffuse, 8/10, and is especially worse following food intake. Recently, he noticed some numbness and tingling of his feet but denies any bloody stool, nausea, vomiting, fevers, weight loss, or focal neurological deficits. What histopathological findings would you expect to find in this patient?
