Although gastrointestinal manifestations in adults are potential prognostic factors for the disease severity, there are limited data on such cases and their standard management in the pediatric population. Case presentation: We herein report an 8-year-old girl case with a 1-year history of epilepsy, who presented bilateral conjunctivitis and progressively widespread bullous, pruritic eruption based on erythematous skin after administering carbamazepine. A diagnosis of carbamazepine-induced TEN was made, and the drug was immediately discontinued. The genetic screening result showed that the patient was positive for the HLA-B*15:02 allele. Then, her condition got worse by developing gastrointestinal involvement, including hematemesis and severely watery bloody diarrhea. Comprising of intravenous immunoglobulin and appropriate dose of systemic steroid raised a favorable outcome in this case. Multidisciplinary care of mucocutaneous involvement, supplemental nutrition, and fluid replacement was also critically warranted. This report aims to contribute to the current literature on TEN-related gastrointestinal manifestations in pediatrics and highlight the need for further investigations in determining the optimal treatment in such cases. Conclusion: In conclusion, we have reported successful treatment of the TEN-related gastrointestinal manifestations in pediatrics, which should be critically considered in patients with SJS/TEN. Since it may significantly contribute to the illness's poor prognosis, further investigations in determining the standard management in such cases are necessary.
