Caecal amoebic colitis mimicking a colorectal cancer

Intestinal Entamoeba Histolytica infection in the UK is rare but it can lead to colitis, abscess formation, colonic perforation and rarely amoeboma. Although most patients are asymptomatic, it can present with a wide range of gastrointestinal symptoms depending on the phase of the infection. We present a case of amoebic colitis that caused diagnostic uncertainty by mimicking a colonic carcinoma.
