# Recurrent Reactive Infectious Mucocutaneous Eruption (RIME) in a Pediatric Patient Triggered by Mycoplasma pneumoniae and Enterovirus Coinfection

## TL;DR

A 10-year-old boy developed a rare skin and mucous membrane condition caused by a co-infection of two viruses, which was initially mistaken for a more severe disease.

## Contribution

This case highlights a rare co-infection and unusual urethral manifestation associated with RIME in a pediatric patient.

## Key findings

- The patient exhibited fever, cough, oral ulcers, and conjunctival injection.
- The condition involved severe mucositis with urethral involvement.
- The eruption was linked to a co-infection by Mycoplasma pneumoniae and enterovirus.

## Abstract

Reactive infectious mucocutaneous eruption (RIME) is an underrecognized condition often misdiagnosed as Stevens-Johnson syndrome (SJS). We present a case of a 10-year-old boy who presented with fever, cough, painful oral ulcers, and conjunctival injection that progressed to severe mucositis with urethral involvement. This case is notable both for the unusual urethral manifestation and for its association with a rare co-infection by Mycoplasma pneumoniae and enterovirus, attributable to RIME.
