Histopathological findings. (A) High-power magnification of duodenum showing histologic features of chronic active duodenitis. There is a manifestation of chronic active colitis with crypt distortion, basal lymphoplasmacytosis and crypt abscess (H&E stain, ×200). (B) High-power magnification of duodenum after infliximab treatment. Note the decreased density of inflammatory cell infiltrates in lamina propria as well as decreased active inflammation compared to those of prior medical treatment. Instead of prominent inflammatory cell infiltrates, subepithelial fibrosis is also noted (H&E stain, ×200).
