Acute lower gastrointestinal bleeding due to low-grade mucinous neoplasm of appendix

Abstract

Introduction

Lower gastrointestinal tract (GIT) bleeding originating from the appendix is rare and may be difficult to diagnose.

Patients and methods

In this case report, we present an 88-year-old male patient who was admitted with hematochezia due to appendiceal bleeding. A colonoscopy revealed bleeding in the appendix orifice so an appendectomy was performed, and bleeding did not recur in the postoperative period.

Results

The results of the microscopic examination showed low-grade mucinous neoplasm (LGMN) of the appendix.

Conclusion

It should be kept in mind that bleeding may originate from the appendix in patients presenting with GIT bleeding. Our patient is the first to present with an acute lower GIT bleed who was diagnosed as having LGMN in the appendectomy specimen.
