case_images: Enhanced abdominal computed tomography (CT) showed irregular thickening of ascending colon wall and proximal intestinal bowel dilation (Figure 1), suggesting malignant right-sided colonic obstruction.
case_images: (A) Endoscopy revealing a narrowed intestinal lumen (red arrow). (B) Prior to placement of SEMS (C) successful stent placement relieving intestinal obstruction (D) x-ray showing location of stent and significant relief of intestinal obstruction.

case_images: SEMS was placed through endoscopy (Figure 2) and bowel obstruction was relieved.
case_images: (A) Coronary angiography revealing 80% and 90% stenosis in the middle and distal left anterior descending branch of the heart (red arrow) (B) stenosis alleviated after placement of 2 stents (red dotted arrow).

case_images: Consecutively, coronary angiography revealed 80% and 90% stenosis in the middle and distal left anterior descending branch of the heart (Figure 3A) respectively and were subsequently alleviated by two coronary stents (Figure 3B).
case_images: (A) A 6.5 cm x  5 cm tumor infiltrating the subserosal layer (red arrow). The previously placed stent can be observed (red dotted arrow) (B) histologic findings of right colonic adenocarcinoma following hematoxylin and eosin stain. Immunohistochemical positivity of (C) MLH1(+) (D) MSH2 (E) MSH6 (F) PMS2 (B-F, magnification x200).

case_images: The tumor size was 6.5 x 5 cm (Figure 4A), infiltrating into the subserosal layer. Postoperative pathological examination revealed highly to moderately differentiated adenocarcinoma (Figure 4B), and 1 positive lymph node (1+/29). Immunohistochemistry findings revealed MLH1(+), MSH2(+), MSH6(+), PMS2(+) (Figures 4C-F).
