title: Amoeboma of colon mimicking colonic carcinoma.
abstract: Entamoeba histolytica is a major cause of diarrhea in the developing countries and it can present with a wide range of gastrointestinal symptoms depending on the phase of the infection. We describe a case of 65-year-old male patient presented with abdominal pain and vomiting. On the clinical and radiological examination provisional diagnosis of colonic carcinoma was suspected. After resection of perforated caecal growth, histopathological sections showed numerous trophozoites of E. histolytica in a background of abundant necrosis. This case revealed differentiation between amoeboma and carcinoma is critical.
