# Capnocytophaga sputigena Tonsillitis in a Patient With Acute Myeloid Leukemia

## TL;DR

This paper describes a rare case of tonsillitis caused by Capnocytophaga sputigena in a patient with acute myeloid leukemia.

## Contribution

The novelty lies in the rare presentation of tonsillitis caused by C. sputigena in a leukemia patient.

## Key findings

- C. sputigena can cause tonsillitis in immunocompromised patients.
- Managing C. sputigena infections presents unique clinical challenges.
- The case highlights the importance of considering rare pathogens in leukemia patients.

## Abstract

Capnocytophaga sputigena is a gram-negative facultatively anaerobic, capnophilic bacterium typically residing in the human oropharyngeal flora. This opportunistic pathogen can cause a wide range of infections, from bacteremia to septic abortion. However, it is exceedingly rare for a patient to present with tonsillitis due to C.
sputigena. Herein, we discuss the presentation, hospital course, and clinical trajectory of a patient experiencing complications of tonsillitis related to C. sputigena in the context of acute myeloid leukemia. Additionally, we delve into the treatment approaches and challenges in managing this particular pathogen.
