- Figure 1.
Abdominal computed tomography (CT) findings. Horizontal (A) and coronal (B) views by CT before conservative treatment. Abdominal CT showed air and fluid collection (arrow) in the mesenteric side of the ascending colon (arrowhead). Three weeks later, CT (horizontal view; C) showed a reduction in the abscess size, but the abscess and fistula formation in the ascending colon remained (arrow).

Contrast enema and colonoscopy findings. A: Contrast enema showed the abscess and fistula formation in the ascending colon (arrow). B: Colonoscopy revealed a fistula in the ascending colon (arrowhead).
- Figure 3.
Macroscopic findings in the resected specimen. A: View of the serous side. B: View of the mucosaI side. The scarred abscess (arrow) was attached to the lateral wall of the ascending colon in which the fistula was located (arrowhead). No evident diverticulum was observed. C: The boundaries of the tumour in the resected specimens were not clear (the dotted line indicates an example). The fistula between DF and the ascending colon was detected (arrow).

Histological and immunohistological features of the tumour. A: The boundary (dotted line) between the tumour (asterisk) and the ascending colon was unclear (×40). M: Mucosa; SM: submucosa; MP: muscularis propria. B: Haematoxylin and eosin staining showed the proliferation of spindle-shaped cells in collagenous stroma (×100). C: Immunohistological staining for β-catenin showed the focal staining of cell nuclei (×100).
