# Double Trouble: Leishmaniasis and Cytomegalovirus Colitis in an Immunocompromised Host

## TL;DR

A 73-year-old immunocompromised man had rare co-occurrence of leishmaniasis and cytomegalovirus colitis after a kidney transplant.

## Contribution

This case report highlights the unusual coexistence of two rare infections in an immunocompromised patient.

## Key findings

- A gastric ulcer with fungal organisms was found in a post-transplant patient.
- Histopathology revealed cytomegalovirus colitis with superimposed leishmaniasis.
- The patient's immunocompromised state likely contributed to the rare infections.

## Abstract

Leishmaniasis is endemic in several areas of the world. It is a chronic protozoan disease transmitted through the bite of the Phlebotomus fly. Unusual localizations of visceral leishmaniasis are extremely rare and are described in immunocompromised patients. We present a case of a 73-year-old man, postliving nonrelated kidney transplant who complained of melena, fatigue, and weight loss. Gastroscopy showed a large ulcer at the lesser curvature of the stomach, and biopsies demonstrated severe ulceration with superimposed fungal organisms. Colonoscopy showed a polyp in the transverse colon, and histopathological examination revealed cytomegalovirus colitis with superimposed leishmaniasis.
