## TL;DR

This paper discusses a rare condition called MIRM caused by Mycoplasma pneumoniae and highlights the need for better understanding and treatment strategies.

## Contribution

The paper presents a case of MIRM and emphasizes the importance of raising awareness about its management due to limited scientific evidence.

## Key findings

- MIRM is a distinct clinical condition from other similar diseases.
- Severe oral mucositis can follow an M. pneumoniae infection.
- Treatment strategies vary depending on disease severity.

## Abstract

Mycoplasma pneumoniae-induced rash and mucositis (MIRM) is a rare clinical pathology distinct from erythema multiforme major and Stevens-Johnson syndrome. We present a case of a patient who developed severe oral mucositis following an M. pneumoniae respiratory tract infection. We aim to raise awareness of MIRM, its varying presentations, and its management, particularly in light of the limited scientific evidence and the variability in treatment strategies depending on disease severity.
