A 10-year-old Hispanic girl with no prior medical conditions or known allergies came to the oral and maxillofacial surgery clinic for evaluation of painless oral lesions of 6 months’ duration. Before her appearance at the clinic, she was seen at an urgent care center with symptoms of sore throat, erythema, and painless swelling of the oral lesions. After administration of nonsteroidal anti-inflammatory drugs, her symptoms improved, and she was discharged home with outpatient follow-up at our clinic.
