Abstract: Mycoplasma pneumoniae-induced rash and mucositis (MIRM) is a distinct emerging clinical entity typically affecting adolescents and adults after a respiratory infection from Mycoplasma pneumoniae. Other known mucocutaneous complications include Stevens-Johnson syndrome, erythema multiforme, and toxic epidermal necrolysis. We present the case of a 24-year-old male patient who developed fever and cough followed by a rapidly evolving mucocutaneous syndrome characterized by oral mucositis, bilateral conjunctivitis, and vesiculobullous skin lesions affecting the palms, soles, and trunk with no evidence of skin detachment. These findings meet the proposed diagnostic criteria for MIRM. This case highlights the importance of recognizing MIRM as a distinct diagnostic entity to guide targeted antimicrobial therapy and avoid unnecessary morbidity associated with misdiagnosis and inappropriate treatment. Early differentiation from Steven-Johnson syndrome and toxic epidermal necrolysis is critical for optimal patient outcomes.
