Figure 2

Pathological findings. (a) Gross appearance of resected specimens. Severe stenosis and ulceration are present at the ileocecal region. (b) Low-magnification image of the area surrounded by the yellow frame. Phlebitis is found in the submucosa beneath the normal mucosa away from the main lesion (hematoxylin/eosin (HE) stain). (c) Low-magnification image of the area surrounded by the orange frame (HE stain). (d) Magnified image of the area surrounded by the green frame. Lymphocytic phlebitis is present but the arteries are not infiltrated (HE stain). (e) Elastica van Gieson stain. (f) Magnified image of the area surrounded by the blue frame. In the middle part of the lesion, there was no phlebitis. There were only ulcers and fibrosis (HE stain).
