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

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 <i>Mycoplasma pneumoniae</i> and enterovirus, attributable to RIME.
