Abstract

Mucosa-associated lymphoid tissue lymphoma (MALT lymphoma) accounts for approximately 5% of non-Hodgkin lymphomas, and the gastrointestinal (GI) tract is the most common site of involvement. The stomach and small intestine are the most common sites of involvement in the GI tract. Colonic MALT lymphoma is a rare condition that comprises only 2.5% of MALT lymphomas and less than 0.5% of all colon cancers. They usually present as colon mass or polyps. In this case report, we present a case of colonic MALT lymphoma diagnosed on random colon biopsies which is very rare.

Highlights

Mucosa-associated lymphoid tissue (MALT) lymphoma, which is referred to as extranodal marginal zone lymphoma, is a form of non-Hodgkin lymphoma (NHL) that predominantly involves the gastrointestinal tract [1,2]

Summary

Introduction

Mucosa-associated lymphoid tissue (MALT) lymphoma, which is referred to as extranodal marginal zone lymphoma, is a form of non-Hodgkin lymphoma (NHL) that predominantly involves the gastrointestinal tract [1,2]. We report a case of incidentally diagnosed colonic MALT lymphoma in an asymptomatic patient during screening colonoscopy who ended up getting colectomy with no recurrence. A 54-year-old female with a past medical history of hypertension underwent screening colonoscopy that revealed mild left-sided diverticulosis but was otherwise unremarkable. How to cite this article Nagra N, Singhvi A R, Singhvi G (March 27, 2020) Mucosa-associated Lymphoid Tissue Lymphoma of Colon: A Case Report and Literature Review of Rare Entity. Repeat colonoscopy was performed after the biopsy results, random biopsies were taken from the rest of the colon, and there was no involvement of the left side. Subsequent imaging and colonoscopy one year later did not reveal any recurrence
