Figure 1 Legends for micrographs. A: Microscopic enteritis (ME), normal villi with pathological increase of T lymphocytes, HE × 10; B: ME with immunohistochemistry for CD3 × 10; C: ME; evident pathological number of T lymphocytes in the superficial epithelium of villi. CD3 immunohistochemistry × 40; D: This diagram is representative of the phases of ME, in addition to the Marsh I ("infiltrated") and Marsh II ("infiltrated-hyperplastic") lesions, it is important to note that a histologically normal-appearing mucosa is a part of the ME spectrum, and that its underlying pathological connotations should therefore not be overlooked nor ignored.
