title: Ameboma: a colon carcinoma-like lesion in a colonoscopy finding.
abstract: Ameboma is a rare complication of amebic colitis presenting as a mass of granulation tissue with peripheral fibrosis and a core of inflammation related to amebic chronic infection. The initial presentations are usually obstruction and low gastrointestinal bleeding. The most common sites are the ascending colon and the cecum. It may mimic colon carcinoma, Crohn's disease, carcinoma of the colon, non-Hodgkin's lymphoma, tuberculosis, fungal infection, AIDS-associated lymphoma and Kaposi's sarcoma in colonoscopy findings. The therapeutic strategy should be combined with antibiotics for invasive dysentery and eradication of luminal cysts.
