Duodenal mucosa showing almost diffuse villous atrophy as the intestinal villi are significantly shrunken or partially flattened (moderate/marked atrophy). The crypts (glands at the base of the villi) become deeper as the body tries to compensate for lost villi. There is a pathological increase in these lymphocytes within the epithelial lining. No evidence of specific granulomas. No evidence of atypia or malignancy.
History of chronic diarrhea with iron deficiency anemia and weight of loss. Duodenal endoscopic biopsy to rule out celiac disease.
Fragments of collective size 6x5 mm.
