Ameboma of colon simulating colonic adenocarcinoma

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.

Amebic colonic stricture: An unusual presentation

“…The majority of amebomas occur in the cecum, usually present as a mass and masquerade as malignancy. [2] Similarly, amebic stricture has also been reported in colon but occurs very rarely. [45] The most frequent sites are the cecum, ascending colon, and rectum.…”

“…[1] Colonic amebiasis is usually diagnosed clinically; however, it may masquerade as malignancy and can lead to a diagnostic dilemma. [2] Hereby, we present a case of a stricture in the transverse colon secondary to amebiasis which was managed surgically. To our knowledge, this is the first case report of amebic stricture in transverse colon.…”
