Intestinal findings. Abdominal CT scan showed localized thickening of the intestinal wall (arrows) (a). Endoscopic study revealed multiple ovoid punched-out ulcers at the terminal ileum (b). HE staining of a biopsy of the terminal ileum showed the presence of ulcer-associated granulation tissues with vascularization and infiltration of cells (original magnification ×100) (c), which were strongly positive for lysozyme (d) (original magnification ×100). Positive stains for CD13, CD14, and CD33 are not shown.
