The diagnosis of celiac disease (CD) is based upon histological findings in duodenal or jejunal biopsy specimens. In recent years it has been seen that the development of CD lesion in the small bowel is a dynamic process which may present in various histological forms. At one end of the spectrum is a mucosa with normal architecture and an increase in intraepithelial lymphocytes; at the other end is the classical flat mucosa. Histological features supporting the diagnosis of CD are architectural changes of the villi and/or crypts, an increase in lamina propria cell density, and an increase in intraepithelial lymphocytes counts. Exact histological classification of the histological findings is required for diagnostic purposes and for monitoring of CD patients. This has become possible by using a modified Marsh classification. We present both the histological presentation of CD and the modified Marsh classification, and the most important differential diagnoses.
