Figure

  • Fig. 1 Colonoscopic findings. (A) Focal erythema with tiny erosion is noted at periappendiceal area. (B) Diffuse erythema with granular mucosal change is noted from rectum to descending colon. (C, D) Multiple, variable sized, sessile polyp with whitish exudate on the top of polyp is noted at rectum.

  • Fig. 2 Histologic findings the lamina propria show an intense infiltrate of lymphocytes, plasma cells, eosinophils and neutrophils. (A) There is evidence of glandular distortion and crypt abscess (arrow). (B) The crypt has ruptured and is spewing its mucinous contents into the surrounding lamina propria (star) (A: H&E, ×10 and B: H&E, ×20).

  • Fig. 3 Histologic findings. (A, B) Mucosal surface show abundant inflammation in the lamina propria and is covered by inflamed granulation tissue and necrotic debris (A: H&E, ×4 and B: H&E, ×10).

  • Fig. 4 Colonoscopic findings. (A, B) Six month later, previous inflammation and cap polyposis are disappeared and changed to fibrotic scar.
