## TL;DR

This paper presents a rare case of severe muscle infection in a healthy young woman following a Group C Streptococcus infection.

## Contribution

The novelty lies in the rare occurrence of multifocal pyomyositis in an immunocompetent individual after toxic shock syndrome.

## Key findings

- The patient developed extensive bilateral pyomyositis after a Group C Streptococcus infection.
- The case highlights the potential severity of pyomyositis even in immunocompetent individuals.
- Toxic shock syndrome preceded the onset of pyomyositis in this case.

## Abstract

Pyomyositis is a bacterial infection deep within the muscles, often leading to multiple intramuscular abscesses. While historically linked with tropical regions, its incidence in temperate zones has been increasing, primarily due to factors such as immunosuppression. Typically, it manifests as a subacute infection, although when caused by Group C Streptococcus and resulting in toxic shock syndrome, it can lead to poorer outcomes. Here, we report a rare case of extensive multifocal bilateral pyomyositis in an immunocompetent young woman, preceded by toxic shock syndrome.
