장기간의 임상 경과중 대량의 하부 장관 출혈을 일으킨 아메바성 대장염

We report a case of atypical form of amebic colitis causing massive lower intestinal bleeding. Recurrent hematochezia lasting for more than 20 years and recent massive rectal bleeding were unusual manifestations of amebic colitis. The macroscopic finding of amebic colitis of the patient at sigmoidoscopy was not diagnositic and led to the patients receiving the therapy with steroid enema. Only sigmoidoscopic biopsies established the diagnosis and appropriate treatment with metronidazole resulted in complete resolution of the hematochezia during 6 months of follow-up.
