Ameboma of Colon Simulating Colonic Adenocarcinoma

Hanish Kataria et al. Int J Appl Basic Med Res. 2018 Jan-Mar.

Abstract

Amebiasis is common in tropical and developing countries with variable symptoms. Ameboma of the colon occurs rarely due to the annular growth of granulation tissue and can present as mass lesion simulating colonic carcinoma in elderly individuals. Due to diagnostic dilemma or in case of complications, for example, acute intestinal obstruction, perforation, or bleeding per rectum, the patient requires urgent surgical exploration and final diagnosis is made on histopathological examination.

Keywords: Adenocarcinoma; ameboma; colon.
