Complete resolution of obstructive colonic amebic pseudotumor with conservative treatment: A case report and literature review.

INTRODUCTION

Entamoeba histolytica is a well-known cause of infectious colitis, it has a worldwide distribution. Presentation ranges from mild diarrhea to occasionally frank dysentery and may spread to involve extra intestinal sites such as the liver, lung, and other organs, in the form of amebic abscesses.

CASE PRESENTATION: Herein, we report a case of amebic pseudotumor wherein the diagnosis was revealed after 2 months of diarrhea.

DISCUSSION: Colonic amebiasis, may rarely form a segmental mass called amebic pseudotumor in patient untreated or inadequately treated during the course of proven amebic colitis. Due to the rarity of colonic amoebic pseudo tumor it is usually discovered incidentally during surgical interventions. However if discovered earlier it responds well to medical treatment and usually resolves within few weeks.

CONCLUSION

So surgical intervention is reserved for complications of this entity manifested by fulminant colitis or colonic perforation.
