ABSTRACT
Inflammatory pseudotumor uncommon parasite colon, the amoeboma cecal is a rare complication of intestinal amebiasis . Its clinical symptoms are nonspecific and a diagnosis problem. We report a case of a 61 years old patient, who had the right flank pain associated to a dysentery syndrome, the physical examination revealed a mass of the right flank. The abdominal scan showed an extra luminal tissue process of the right colon. The colonoscopy objective an extrinsic compression of the right colon obstructing the colonic lumen. The evolution was marked by the occurrence of an occlusive syndrome and the patient was operated urgently and a right colectomy was performed. Histological examination was in favor of a cecal amoebome. The postoperative course was uneventful and the evolution one year is favorable. The amoebome is difficult to diagnose, its radiological and endoscopic appearance can simulate colon cancer and lead to improper surgical treatment. Positive serology is the diagnosis and allows to initiate effective medical treatment. The amoebome should be considered in a process without extrinsic evidence confirming neoplasia, the diagnosis confirmed by serology avoids surgery
