摘　　要：BACKGROUND Recently reported cases of pyogenic liver abscess associated with colonic cancer in the absence of underlying disease,have included a small number of cases of gastric heterotopia(GHT).GHT is a congenital anomaly composed of ectopic gastric mucosa and can occur anywhere in the gastrointestinal tract but is more frequently encountered in the cervical esophagus.However,it is rarely observed in colon.Furthermore,most reported cases of GHT of the colon involved the rectum,and GHT involving the colon proximal to the rectum is rare.CASE SUMMARY An 83-year-old male patient presented with fever and a diagnosis of pyogenic liver abscess.Colonoscopy was performed for colon cancer workup and revealed a 1.0 cm sized polyp at the transverse colon.The polyp was removed by endoscopic mucosal resection by monopolar electrocauterization using a snare.Pathological examination revealed GHT.After administering intravenous antibiotics,the patient recovered well.CONCLUSION GHT in the colon could affect the development of pyogenic liver abscess by enabling hematogenous propagation of Klebsiella pneumoniae through mucosal damage.However,more study is needed due to the lack of cases.
