Figure 2 Intraepithelial lymphocytes and Marsh classification. A: Schema of the intraepithelial distribution of the intraepithelial lymphocytes (top, side and bottom, see text); B: Marsh 0, normal villous architecture with en-face cut (HE, × 100); C: Marsh I (HE, × 100); D: Marsh IIIA (HE, × 100); E: Marsh IIIB (HE, × 100); F: Marsh IIIC (HE, × 100). Marsh-Oberhuber classification is often shortened as Marsh.
