Gastric heterotopia of colon found cancer workup in liver abscess: A case report

Figure 1 Abdominal computed tomography images showing the pyogenic liver abscess. A and B: Axial and coronal images showing a ca. 2 cm × 2.5 cm sized, ill-defined, low attenuation nodular lesion in liver segment 6.

Figure 2 Colonoscopy during cancer workup. A: Colonoscopy revealed about 1.0 cm sized, semi-pedunculated polyp at the transverse colon; B: The polyp was removed by endoscopic mucosa resection by monopolar electrocauterization using a snare; C: The polyp was successfully removed.

Figure 3 Histology showed that the excised tissue was consistent with heterotopic gastric tissue with intestinal metaplasia, fibrosis, and vascular and nervous tissue proliferation. HE (× 100).
