Coronavirus-disease-2019-associated Stevens-Johnsons syndrome in a 15-year-old boy: a case report and review of the literature.

Background: Stevens-Johnson syndrome (SJS) is a life-threatening condition characterized by high fever and severe mucocutaneous lesions, often triggered by drugs or infection. During the coronavirus disease 2019 pandemic, there was a marked increase in Stevens-Johnson syndrome cases, but relatively few cases were reported in children. The present article reports a pediatric case of Stevens-Johnson syndrome due to coronavirus disease 2019 infection and provides a review of the most relevant literature.

Case presentation: A previously healthy 15-year-old Han Chinese boy from China presented to the hospital with oral ulcers, conjunctival hyperemia, and widespread maculopapular rash. He had a history of fever 9 days prior and tested positive for coronavirus disease 2019 infection. Upon admission, his rash and mucosal lesions worsened, with the development of blisters on the fingertips of both hands, ocular pain, photophobia, and erosive lesions on the genital mucosa with exudation. He was diagnosed with Stevens-Johnson syndrome and received treatment with methylprednisolone, intravenous immunoglobulin, and dermatological and mucosal care. The patient's condition was managed, and the dosage of high-dose intravenous methylprednisolone was tapered down, followed by a transition to oral prednisolone. He was discharged without sequelae.

Conclusion: We should be aware that coronavirus disease 2019 infection is associated with the development of Stevens-Johnson syndrome in children and may lead to a wide spectrum of dermatologic presentations. Although Stevens-Johnson syndrome is a relatively rare condition, given its potentially serious consequences, it is crucial to identify it as early as possible and to take appropriate preventive and therapeutic measures to reduce complications and improve the quality of life for patients.
