Reactive Infectious Mucocutaneous Eruption: A Rising Enigma

Area of Science:

• Pediatric Infectious Diseases
• Dermatology
• Immunology

Background:

• Reactive infectious mucocutaneous eruption (RIME) is a rare condition primarily affecting children.
• It typically follows a respiratory infection, frequently Mycoplasma pneumoniae.
• RIME is characterized by severe mucositis with minimal skin lesions.

Purpose of the Study:

• To present a pediatric case of RIME.
• To emphasize diagnostic challenges and treatment strategies.
• To highlight the importance of early recognition and management.

Main Methods:

• Case report of a nine-year-old male with severe oral mucositis and urinary retention.
• Etiological investigation including respiratory secretions analysis and serology for Mycoplasma pneumoniae.
• Treatment with azithromycin, intravenous immunoglobulin, and methylprednisolone.

Main Results:

• Mycoplasma pneumoniae identified as the causative agent.
• Patient presented with severe oral mucositis, penile lesion, cutaneous lesions, and conjunctival hyperemia.
• Successful clinical improvement following treatment with azithromycin, IVIG, and methylprednisolone.

Conclusions:

• RIME requires careful differentiation from Stevens-Johnson syndrome, often presenting with a better prognosis.
• Early recognition and supportive care are crucial for optimal patient outcomes.
• Multidisciplinary management is essential for addressing the complexities of RIME.
