Backgound: The gold standard test for evaluation of intestinal malabsorption is biopsy. The various yet similar, abnormal mucosal architecture patterns in intestinal malabsorption makes it difficult for the pathologist to report its etiological cause
Methods-We analyzed the clinical presentation, endoscopic and histological features of 328 consecutive patients with complaints suggestive of malabsorption syndrome. The spectrum of disease in these patients were studied and divided into four groups on the basis of histologic features and correlated with clinical/endoscopic findings
Results: Group1 were entities usually associated with a diffuse severe villous abnormality and crypt hyperplasia ,all 57 cases were of  celiac disease (17.3%), Group 2 were entities usually associated with a variable villous abnormality and crypt hypoplasia, included 7 cases-malnourished 5(1.5%) and post chemotherapy 2(0.6%), Group 3 were entities usually associated with a nonspecific variable villous abnormality, usually not flat included 252 biopsies- Tropical sprue 16(4.8%), nonspecific duodenitis/jejunitis/ileitis 212 (64.6%), peptic duodenitis 16(4.8%), intestinal tuberculosis 8 (2.43%), and in Group 4 were entities associated with variable villous abnormalities illustrating specific diagnostic changes included 12 cases-giardiasis 2 (0.6%), Crohn’s disease 8 (2.4%), intestinal lymphangiectasia 1 (0.3%), lymphoma 1(0.34%).
