Figure 1

Representative hematoxylin and eosin (H&E) and immunohistochemical staining of inflammatory fibroid polyp (IFP). (a) Coronal (yellow arrow on mass). (b) Axial CT scan with contrast revealed ileocolonic intussusception measuring in maximum longitudinal axis about 7.4 cm. (c) Gross examination revealed a large pedunculated polypoid mass measuring 7.5 cm with attached stalk measuring 5 cm, located at the ileocecal valve. (d) Submucosal mass characterized by spindle cells embedded in a loose myxoid matrix (H&E; 2x). (e) Heavy inflammatory infiltrate with eosinophils and mast cells are observed (H&E; 20x).
